[0002] Professional test and measurement instruments, with their increasingly complex functions and parameters, come in a wide variety of forms, including those with touchscreen displays, non-touchscreen displays, and touchscreen displays with knobs. These instruments are designed to help users quickly and accurately set and adjust parameters.

[0003] During the invention process, the inventors discovered shortcomings in existing technologies: When using a touchscreen display in test and measurement instruments, users need to continuously click virtual buttons to observe the effects of parameter changes. The number and speed of clicks for large-scale coarse or fine adjustments are difficult to control, leading to inconvenience and a high risk of error. If the test and measurement instrument uses multiple physical buttons and knobs without a touchscreen, operation is cumbersome, knobs cannot be reused or maximized, and the range of parameter types controlled by a single knob is limited.

[0020] Furthermore, based on the click operations and / or touch measurement commands in the test measuring instrument, the test measurement scenario required by the user is obtained, including: based on the click operations and / or touch measurement commands of the test measuring instrument used to select the first target alternative setting parameter for configuring the currently unpaired knob in the menu setting function of the target direction measurement line in the currently active target function window, the single-window parameter appending setting scenario required by the user is obtained; the current adjustment parameter matching the test measurement scenario is obtained, and a pairing relationship is established between the current adjustment parameter and the first knob and / or the second knob in the test measuring instrument, including: obtaining the first target alternative setting parameter as the current adjustment parameter, and obtaining the most recently paired knob; among the first knob and the second knob, selecting the target knob that is not the most recently paired knob to establish a pairing relationship with the current adjustment parameter.

[0021] Furthermore, based on the click operations and / or touch measurement commands in the test and measurement instrument, the test and measurement scenario required by the user is obtained, including: based on the click operations and / or touch measurement commands of the test and measurement instrument used to configure the second target alternative setting parameters in the menu setting function of the target direction measurement line in the currently active target function window, the single-window virtual keyboard parameter setting scenario required by the user is obtained; the current adjustment parameters matching the test and measurement scenario are obtained, and a pairing relationship is established between the current adjustment parameters and the first knob and / or the second knob in the test and measurement instrument, including: obtaining the target pairing knob matching the second target alternative setting parameters, and establishing a pairing relationship between each virtual key in the virtual keyboard and the target pairing knob; wherein, the virtual key required by the user is identified among all virtual keys by rotating the target pairing knob to generate operation description information, and the virtual key for user confirmation input is identified by pressing the target pairing knob.

A pairing relationship is established between the first priority parameter and the first knob, and a pairing relationship is established between the second priority parameter and the second knob. If yes, the pairing relationship between the current adjustment parameter and the first knob and / or the second knob in the test measuring instrument is completed.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0032] It should also be noted that, for ease of description, the accompanying drawings show only the parts relevant to the invention and not all of them.

Furthermore, the order of the operations can be rearranged. The process can be terminated when its operation is completed, but it may also have additional steps not included in the drawings.

[0033] The terms "first" and "second," etc., used in the specification, claims, and drawings of this invention are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units may include steps or units not listed, but rather steps or units not listed.

[0034] Example 1

[0035] Figure 1 This is a schematic diagram of a test and measuring instrument according to Embodiment 1 of the present invention. This embodiment is applicable to situations where the test and measuring instrument sets and adjusts parameters, such as... Figure 1 As shown, the system may include: a display screen 110, a first knob 120 and a second knob 130, and a controller 140 connected to the display screen 110, the first knob 120 and the second knob 130 respectively.

[0036] The first knob 120 and the second knob 130 are used to listen to the user's pressing operation and feed back the listened pressing operation to the controller 140.

[0037] The controller 140 is used to obtain the test and measurement scenario required by the user based on the pressing operation, and to obtain the screen display content matching the test and measurement scenario and send it to the display screen 110 for display; to obtain the current adjustment parameters matching the test and measurement scenario, and to establish a pairing relationship between the current adjustment parameters and the first knob 120 and / or the second knob 130.

[0038] The first knob 120 and the second knob 130 are also used to listen to the user's rotation operation and feed back the operation description information matching the rotation operation to the controller 140;

[0039] The controller 140 is also used to determine the adjustment value of the target adjustment parameter based on the operation description information fed back by the first knob 120 or the second knob 130, and to feed back the updated display content according to the adjustment value to the display screen 110 for updating and display.

[0040] The first knob can be a button on the test instrument, which can be used to select and adjust parameters by pressing and rotating. Specifically, the first knob is located above the second knob, and the first knob has a higher priority than the second knob. When the test instrument receives the parameter to be adjusted, it will use the first knob for control.

[0041] Understandably, the second knob is also a button on the test instrument, which can be used to select and adjust parameters by pressing and rotating it. Specifically, the second knob is located below the first knob, and the second knob has a lower priority than the first knob.

[0042] The test and measurement scenario can be any scenario requiring the measurement of different parameters, including single-window measurement scenarios, single-window parameter appending settings scenarios, single-window virtual keyboard parameter settings scenarios, and multi-window parameter settings scenarios. The currently adjusted parameter can be the parameter that needs to be adjusted using the first knob and / or the second knob. The operation description information can be a statistical description of the step value and rotation speed of the first knob and / or the second knob during the adjustment of the current parameter. The adjustment value can be a numerical value calculated using the currently adjusted parameter, the step value, and the rotation speed.

[0043] Specifically, the test and measurement instrument can be an oscilloscope; there is no limitation here.

[0044] For example, the controller listens for user clicks on the first and second knobs and sends the detected clicks back to the controller. Suppose the cursor measurement function is selected by clicking the first knob. The controller can then obtain the single-window measurement scenario requested by the user and send the screen display content matching the test measurement scenario to the display screen for presentation.

[0045] Furthermore, the current adjustment parameters matching the single-window measurement scenario are obtained. Assuming there are two current adjustment parameters (current adjustment parameter 1 and current adjustment parameter 2), pairing relationships can be established with the first knob and the second knob respectively. For example, current adjustment parameter 1 is paired with the first knob, and current adjustment parameter 2 is paired with the second knob.

[0046] Accordingly, once the pairing relationship is established, the first knob is rotated to adjust the current adjustment parameter 1, and the operation description information matching the rotation operation is fed back to the controller. Similarly, the second knob can be adjusted to further determine the current adjustment parameter 2.

[0047] Finally, the controller uses the operation description information to determine the adjustment value corresponding to the current adjustment parameter 1 and the adjustment value corresponding to the current adjustment parameter 2, and then feeds back the updated display content to the display screen for updating and display.

[0048] Optionally, it also includes a first indicator light pair matched with the first knob and a second indicator light pair matched with the second knob; wherein the first indicator light pair and the second indicator light pair respectively include a horizontal adjustment indicator light and a vertical adjustment indicator light; the first indicator light pair and the second indicator light pair are respectively connected to the controller; the controller is further configured to, after establishing a pairing relationship between the current adjustment parameter and the first knob and / or the second knob, obtain a target indicator light that matches the measurement line direction or parameter type of the current adjustment parameter from the indicator light pair matched with the paired knob of the current adjustment parameter, and trigger the lighting of the target indicator light.

[0049] The first indicator light pair can be used to indicate the adjustment of the first knob, and may include a horizontal adjustment indicator light and a vertical adjustment indicator light. When the first knob is adjusted, either the horizontal or vertical adjustment indicator light can be turned on. The second indicator light pair can be used to indicate the adjustment of the second knob, and may include a horizontal or vertical adjustment indicator light. When the second knob is adjusted, either the horizontal or vertical adjustment indicator light can be turned on. The horizontal adjustment indicator light can be used to indicate a horizontal parameter adjustment of the first knob and / or the second knob. The vertical adjustment indicator light can be used to indicate a vertical parameter adjustment of the first knob and / or the second knob. The measurement line direction can describe the direction of the measurement line for the currently adjusted parameter, and may include a horizontal or vertical direction. The parameter type can describe the type of parameter, and may include horizontal and vertical parameters.

[0050] Specifically, horizontal parameters can include time units (s / ms / us / ns / ps / fs, etc.), frequency units (GHZ / MHZ / kHz / Hz / mHZ, etc.), percentages (%), and bit rate units (bps, etc.). Furthermore, vertical parameters can include voltage units (V / mV / μV / nV, etc.), current units (A / mA / μA, etc.), power units (kW / W / mW, etc.), unknown type units (U / mU, etc.), and all-numeric types. These parameters include, but are not limited to, waveform attributes, graphic image attributes, function attributes, and object attributes.

[0051] Continuing the previous example, since the current adjustment parameter 1 is paired with the first knob, the current adjustment parameter 2 is paired with the second knob. Assuming the parameter type of the current adjustment parameter 1 is a horizontal parameter, adjusting the current adjustment parameter 1 will activate the corresponding horizontal adjustment indicator light. If the parameter type of the current adjustment parameter 2 is a vertical parameter, adjusting the current adjustment parameter 2 will activate the corresponding vertical adjustment indicator light.

[0052] The advantage of this setup is that by activating the corresponding horizontal or vertical adjustment indicator light when adjusting the current parameter, it becomes clearer whether the parameter type being adjusted matches the indicator light, thus making parameter adjustments more convenient for the user.

[0053] Optionally, the display screen is specifically a touch display screen; the touch display screen is further configured to respond to the user's touch measurement command and send the touch measurement command to the controller; the controller is further configured to respond to the touch measurement command, obtain the test measurement scenario required by the user, and obtain screen display content matching the test measurement scenario and send it to the display screen for display.

[0054] The touch display allows users to select the appropriate function on the test instrument via touch. Touch measurement commands are generated by the user selecting a function on the touch screen and can be sent to the controller.

[0055] In this embodiment, the corresponding test and measurement scenario can be selected not only by pressing the first knob and / or the second knob, but also by using the touch measurement command on the touch display.

[0056] The advantage of this setup is that the user's required measurement and testing scenarios can be obtained through the touch screen. In addition to selecting the test and measurement scenarios by pressing the first knob and / or the second knob, the touch screen can also be used to enrich the operation methods for selecting measurement and testing scenarios, allowing users to complete the selection of test and measurement scenarios in a more diversified way.

[0057] The technical solution provided in this invention includes a measurement and testing instrument comprising a display screen, a first knob, a second knob, and a controller. The first and second knobs are used to monitor user click operations and provide feedback to the controller. The controller is used to acquire the user's required test and measurement scenario based on the click operations, acquire the screen display content, and send it to the display screen for display; acquire the current adjustment parameters and establish a pairing relationship; the first and second knobs monitor rotation operations and provide operation description information to the controller; the controller is also used to determine the adjustment value of the target adjustment parameter based on the operation description information and provide feedback to the display screen for updated display. This invention solves the problems of limited adjustable parameter types, difficulty in controlling the number of clicks and click speed for large-scale coarse or fine adjustments, and inconvenient operation, improving operational flexibility and parameter adjustment efficiency.

[0058] Example 2

[0059] Figure 2a This is a flowchart illustrating a dual-knob parameter adjustment method according to Embodiment 2 of the present invention. This embodiment is applicable to the setting and adjustment of parameters in a test and measuring instrument. The method in this embodiment can be executed by the controller in the test and measuring instrument.

[0060] Accordingly, the method specifically includes the following steps:

[0061] S210. Based on the click operation in the test and measurement instrument, obtain the test and measurement scenario required by the user, and obtain the screen display content matching the test and measurement scenario and send it to the display screen for display.

[0062] S220. Obtain the current adjustment parameters that match the test and measurement scenario, and establish a pairing relationship between the current adjustment parameters and the first knob and / or the second knob.

[0063] S230. Based on the operation description information fed back by the first knob or the second knob, determine the adjustment value of the target adjustment parameter, and feed back the updated display content according to the adjustment value to the display screen for updating and display.

[0064] Optionally, it also includes: responding to a touch measurement command in the test and measurement instrument, obtaining the test and measurement scenario required by the user, and obtaining screen display content matching the test and measurement scenario and sending it to the display screen for display.

[0065] Understandably, the test and measurement instrument can select the corresponding test and measurement scenario not only by pressing the first knob and / or the second knob, but also by using touch measurement commands on the touch display.

[0066] Optionally, after establishing the pairing relationship between the current adjustment parameter and the first knob and / or the second knob in the test measuring instrument, the method further includes: acquiring a target indicator light that matches the measurement line direction or parameter type of the current adjustment parameter from the indicator light pair matched with the paired knob of the current adjustment parameter, and triggering the illumination of the target indicator light.

[0067] Specifically, the target indicator light may include a horizontal adjustment indicator light and a vertical adjustment indicator light.

[0068] For example, suppose the current testing and measuring instrument has two current adjustment parameters, namely current adjustment parameter 1 and current adjustment parameter 2. Current adjustment parameter 1 can be paired with the first knob, and current adjustment parameter 2 can be paired with the second knob. Assuming current adjustment parameter 1 is a horizontal parameter, adjusting current adjustment parameter 1 will illuminate the corresponding horizontal adjustment indicator light. Similarly, if current adjustment parameter 2 is a vertical parameter, adjusting current adjustment parameter 2 will illuminate the corresponding vertical adjustment indicator light.

[0069] Optionally, based on the click operation and / or touch measurement command in the test measuring instrument, the user's required test measurement scenario is obtained, including: based on the click operation and / or touch measurement command used by the test measuring instrument to activate the cursor measurement function in the target function window, the user's required single-window measurement scenario is obtained; the current adjustment parameters matching the test measurement scenario are obtained, and a pairing relationship is established between the current adjustment parameters and the first knob and / or the second knob in the test measuring instrument, including: obtaining the horizontal measurement line adjustment parameters and the vertical measurement line adjustment parameters matching the single-window measurement scenario; according to the preset adjustment parameter priority, obtaining the first priority parameter and the second priority parameter in the horizontal measurement line adjustment parameters and the vertical measurement line adjustment parameters respectively; establishing a pairing relationship between the first priority parameter and the first knob, and establishing a pairing relationship between the second priority parameter and the second knob.

[0070] The target function window can be a window in the test and measuring instrument where functions can be selected. The test and measuring instrument can select functions in this target function window by touching the display screen or by pressing the knob.

[0071] The cursor measurement function allows for parameter measurement within a test and measurement instrument using horizontal or vertical measurement lines. Specifically, it can measure the amplitude and period of the waveform under test. The single-window measurement scenario involves measuring parameters within a single window of the test and measurement instrument. Adjusting parameters using the horizontal measurement line involves moving the horizontal line to measure the current adjustment parameter. Similarly, adjusting parameters using the vertical measurement line involves moving the vertical line to measure the current adjustment parameter.

[0072] Understandably, parameter adjustment priorities can be determined by the frequency of use of multiple adjustment parameters in the test window of the measuring instrument. Specifically, a higher priority indicates a higher frequency of user adjustment of the current parameter, and a lower priority indicates a lower frequency of user adjustment. For the adjustment parameter with the highest priority, the pairing relationship between that parameter and the first knob is first determined, and then the pairing relationships between other adjustment parameters and the second and / or first knobs are determined sequentially.

[0073] The first priority parameter can be the highest priority adjustment parameter among multiple adjustment parameters in the test window of the test instrument. The second priority parameter can be the second highest priority adjustment parameter among multiple adjustment parameters in the test window of the test instrument.

[0074] like Figure 2b The diagram shows the structure of the parameter adjustment interface in a single-window measurement scenario controlled by a pair of knobs in a test measuring instrument. The first knob 101 is located on the far right of the instrument, the second knob 102 is below it, and the display screen is in the middle. The cursor measurement function can be selected by pressing the knobs or touching the display screen.

[0075] Furthermore, after selecting the cursor measurement function on the test instrument, the horizontal measurement line adjustment parameter 201 and the vertical measurement line adjustment parameter 202 can be determined. The control system pairs the first knob 101 to monitor the time parameter (unit: time) of the horizontal measurement line 201, and simultaneously illuminates the corresponding horizontal direction indicator light. Similarly, the pairing of the second knob 102 monitors the voltage parameter (unit: voltage) of the vertical measurement line 202, and simultaneously illuminates the corresponding vertical direction indicator light.

[0076] Accordingly, based on the setting relationship between the horizontal and vertical measurement line adjustment parameters, it can be seen that by rotating the first knob 101 to change the value of the time parameter of the horizontal measurement line 201, the horizontal measurement line 201 can be moved along the X-axis; by rotating the second knob 102 to change the value of the voltage parameter of the vertical measurement line 202, the vertical measurement line 202 can be moved along the Y-axis.

[0077] The advantage of this setup is that by using a pair of knobs to adjust parameters through a test measuring instrument, the pair of knobs can be reused and maximized, improving user convenience and operational efficiency.

[0078] Optionally, based on the click operation and / or touch measurement command in the test measuring instrument, the user's required test measurement scenario is obtained, including: based on the click operation and / or touch measurement command of the test measuring instrument used to activate the menu setting function of the target direction measurement line in the target function window, the user's required single-window parameter setting scenario is obtained; the current adjustment parameter matching the test measurement scenario is obtained, and a pairing relationship is established between the current adjustment parameter and the first knob and / or the second knob in the test measuring instrument, including: obtaining all alternative setting parameters matching the single-window parameter setting scenario as the current adjustment parameter, and obtaining the quantity value of the current adjustment parameter; when the quantity value is greater than 2, according to the preset adjustment parameter priority, the first priority parameter and the second priority parameter are obtained respectively from all the current adjustment parameters; a pairing relationship is established between the first priority parameter and the first knob, and a pairing relationship is established between the second priority parameter and the second knob.

[0079] The menu setting function describes a specific setting function within the menu of the test and measuring instrument. Users can select the corresponding function from the menu by pressing a knob or touching the display screen on the test and measuring instrument. The all-option setting parameters can be viewed within the current single-window parameter setting scenario, allowing access to all adjustable alternative setting parameters corresponding to the target window. Furthermore, it allows for the counting of the number of currently adjustable parameters among all alternative setting parameters.

[0080] Understandably, when the current adjustment parameter value is determined to be 1, a matching relationship between the current adjustment parameter and the first knob can be directly established, and the corresponding target indicator light (which can be a horizontal adjustment indicator light or a vertical adjustment indicator light) can be matched according to the measurement line direction or parameter type of the current adjustment parameter. The value of the current adjustment parameter can be adjusted by rotating the first knob.

[0081] In an optional implementation of this embodiment, when the number of current adjustment parameters is determined to be 2, the current adjustment parameters can be set as current adjustment parameter 1 and current adjustment parameter 2. First, it is necessary to determine the priority of the adjustment parameters corresponding to the current adjustment parameters. Assuming that current adjustment parameter 1 has a higher priority (i.e., current adjustment parameter 1 is the first priority parameter) and current adjustment parameter 2 is the second priority parameter, further, current adjustment parameter 1 can be paired with the first knob, and current adjustment parameter 2 can be paired with the second knob.

[0082] In this embodiment, when the number of current adjustment parameters is determined to be greater than 2, it is assumed that there are 4 current adjustment parameters, namely current adjustment parameter 1, current adjustment parameter 2, current adjustment parameter 3 and current adjustment parameter 4.

[0083] Furthermore, based on the preset adjustment parameter priorities, the first priority parameter can be determined as the current adjustment parameter 3, the second priority parameter as the current adjustment parameter 1, and the adjustment parameter priority corresponding to the current adjustment parameter 2 is higher than that of the current adjustment parameter 4. A pairing relationship can be established between the first priority parameter (i.e., the current adjustment parameter 3) and the first knob, as well as a pairing relationship can be established between the second priority parameter (i.e., the current adjustment parameter 1) and the second knob.

[0084] Optionally, based on the click operation and / or touch measurement command in the test measuring instrument, the user's required test measurement scenario is obtained, including: based on the click operation and / or touch measurement command of the test measuring instrument used to select the first target alternative setting parameter of the currently unpaired knob in the menu setting function of the target direction measurement line in the currently active target function window, the user's required single window parameter appending setting scenario is obtained; the current adjustment parameter matching the test measurement scenario is obtained, and a pairing relationship is established between the current adjustment parameter and the first knob and / or the second knob in the test measuring instrument, including: obtaining the first target alternative setting parameter as the current adjustment parameter, and obtaining the most recently paired knob; among the first knob and the second knob, selecting the target knob that is not the most recently paired knob to establish a pairing relationship with the current adjustment parameter.

[0085] The first target alternative setting parameter can be any of the adjustable parameters among all the alternative setting parameters corresponding to the target window, excluding the first priority parameter and the second priority parameter. The single-window parameter appending setting scenario can be a scenario where other adjustable parameters are being adjusted.

[0086] Continuing the previous example, once it's confirmed that the adjustments to current adjustment parameter 3 and current adjustment parameter 1 are complete, the adjustments to current adjustment parameter 2 and current adjustment parameter 4 need to be made next. Since current adjustment parameter 3 and current adjustment parameter 1 are the first priority parameter and the second priority parameter, respectively, the first target alternative setting parameter is selected from current adjustment parameter 2 and current adjustment parameter 4.

[0087] Furthermore, since the priority of the adjustment parameter corresponding to the current adjustment parameter 2 is higher than that of the current adjustment parameter 4, the current adjustment parameter 2 is selected as the first target candidate setting parameter. Then, the most recently paired knob is retrieved, specifically, a pairing relationship is established between the current adjustment parameter 1 and the second knob. Next, among the first and second knobs, a target knob that is not the most recently paired knob is selected to establish a pairing relationship with the current adjustment parameter 2, thus establishing a pairing relationship between the current adjustment parameter 2 and the first knob. Similarly, a pairing relationship is established between the current adjustment parameter 4 and the second knob.

[0088] like Figure 2cThe diagram shows the structure of the parameter adjustment interface in a single-window parameter setting scenario controlled by a pair of knobs in a test and measurement instrument. The first knob 101 is located on the far right of the instrument, the second knob 102 is below it, and the display screen 2 is in the middle. The cursor measurement function can be selected by pressing the knobs or touching the display screen. The single-window parameter setting scenario is window 3, which can retrieve the currently adjusted parameters matching the test and measurement scenario, namely, currently adjusted parameter 301, currently adjusted parameter 302, and currently adjusted parameter 303 (here, the parameter priority corresponding to currently adjusted parameter 301 can be set to the highest, the parameter priority corresponding to currently adjusted parameter 302 to the second highest, and the parameter priority corresponding to currently adjusted parameter 303 to the lowest). The number of currently adjusted parameters is determined to be 3. Since the number is greater than 2, based on the adjustment parameter priority, the first priority parameter is currently adjusted parameter 301, and the second priority parameter is currently adjusted parameter 302. A pairing relationship can be established between currently adjusted parameter 301 and the first knob, and a pairing relationship can be established between currently adjusted parameter 302 and the second knob. Furthermore, after determining that the current adjustment parameter 301 and the current adjustment parameter 302 have been adjusted, the pairing relationship between the current adjustment parameter 303 and the first knob is then established, and the current adjustment parameter 303 is adjusted by the first knob.

[0089] Specifically, pressing the knob or clicking the waveform function menu on the touch display screen 2 will open window 3. The control system assigns the frequently used time base parameter 301 (unit: time) to the first knob 101 for monitoring based on fixed priority, and simultaneously illuminates the corresponding horizontal directional indicator light on the first knob 101; it also assigns the displacement parameter 302 (unit: time) to the second knob 102 for monitoring, and simultaneously illuminates the corresponding horizontal directional indicator light on the second knob 102. Rotating the first knob 101 changes the value of the time base parameter 301, and pressing the first knob 101 resets the value of the time base parameter 301. Similarly, rotating the second knob 102 changes the value of the time base parameter 302, and pressing the second knob 102 resets the value of the time base parameter 302. Click on the extended parameter 303 (unit of measurement: unknown type) in the pop-up window 3. The control system will switch the monitoring target of the first knob 101 to parameter 303. The horizontal directional indicator light corresponding to the first knob 101 will turn off and the vertical directional indicator light will turn on. The value of parameter 303 can be changed by rotating and pressing the first knob 101.

[0090] The advantage of this setup is that different parameters can be adjusted by using a pair of knobs alternately on the test instrument. This allows the pair of knobs to be reused and maximized, and also enables the adjustment of multiple parameters, thus enriching the testing functions of the test instrument.

[0091] Optionally, based on the pressing operations and / or touch measurement instructions in the test measuring instrument, the test measurement scenario required by the user is obtained, including: based on the pressing operations and / or touch measurement instructions of the test measuring instrument used to configure the second target alternative setting parameters in the menu setting function of the target direction measurement line in the currently active target function window, the single-window virtual keyboard parameter setting scenario required by the user is obtained; the current adjustment parameters matching the test measurement scenario are obtained, and a pairing relationship is established between the current adjustment parameters and the first knob and / or the second knob in the test measuring instrument, including: obtaining the target pairing knob matching the second target alternative setting parameters, and establishing a pairing relationship between each virtual key in the virtual keyboard and the target pairing knob; wherein, the virtual key required by the user is identified among all virtual keys by rotating the target pairing knob to generate operation description information, and the virtual key for user confirmation input is identified by pressing the target pairing knob.

[0092] The second target alternative setting parameter can be an alternative setting parameter that can be adjusted via a virtual keyboard during the adjustment of the current setting parameter. The virtual keyboard can be a keyboard that allows adjustment of the second target alternative setting parameter by rotating a knob and / or pressing a button. Specifically, rotating the knob traverses each number, symbol, or deletion operation on the virtual keyboard. When a parameter is selected on the virtual keyboard, pressing the knob selects that parameter. After the current parameter adjustment is complete, the virtual keyboard exits.

[0093] In a single-window virtual keyboard parameter setting scenario, selecting a parameter to be adjusted will activate (or trigger) a pop-up window, allowing for more accurate parameter adjustments.

[0094] like Figure 2d The diagram shows the structure of the parameter adjustment interface in a single-window virtual keyboard parameter setting scenario controlled by a pair of knobs in a test measuring instrument. The first knob 101 is located on the far right of the test measuring instrument, the second knob 102 is below it, and the display screen 2 is in the middle. The cursor measurement function can be selected by pressing the knobs or touching the display screen. The single-window parameter setting scenario is window 3, which can retrieve the currently adjusted parameters matching the test measurement scenario, namely current adjustment parameter 301 and current adjustment parameter 302. The single-window virtual keyboard parameter setting scenario corresponding to current adjustment parameter 301 is window 4. Window 4 includes a virtual keyboard display screen 401, a virtual number 1 key 402, a virtual number 2 key 403, and a confirmation virtual key 404.

[0095] In the test and measurement instrument, by pressing the knob or clicking the waveform function menu setting function on the touch display screen 2, a pop-up window 3 appears. The control system assigns the time base parameter 301 (unit of measurement: time) that is frequently used by the user to the first knob 101 for monitoring according to a fixed priority, and at the same time illuminates the horizontal direction indicator light corresponding to the first knob 101; it assigns the displacement parameter 302 (unit of measurement: time) to the second knob 102 for monitoring, and at the same time illuminates the horizontal direction indicator light corresponding to the second knob 102.

[0096] Furthermore, when the time base parameter 301 of the pop-up window 3 is clicked to bring up the virtual keyboard window 4, the control system switches the monitoring target of the first knob 101 to the first virtual key 402 of the virtual keyboard window 4. By rotating the first knob 101 clockwise by one unit, the control system switches the monitoring target of the first knob 101 to the second virtual key 403 of the virtual keyboard window 4. Then, by rotating it counterclockwise by one unit, the control system switches the monitoring target of the first knob 101 back to the first virtual key 402 of the virtual keyboard window 4.

[0097] Similarly, rotating the first knob 101 allows switching the monitoring target to any virtual key. When a virtual key is selected, pressing the first knob 101 displays the corresponding parameter value in the input box 401. Finally, rotating the first knob 101 switches to the virtual keyboard's confirmation button 404, and pressing the first knob 101 confirms the selection. This updates the parameter value in the input box 401 to the time base parameter 301, closes the virtual keyboard window 4, and the control system switches the monitoring target of the knob 101 back to the time base parameter 301.

[0098] The advantage of this setup is that by using a pair of knobs to alternately control the virtual keyboard with the test instrument to adjust the parameters, the selection of parameters can be determined more accurately, avoiding multiple adjustments for larger parameters, thereby improving the accuracy and efficiency of parameter adjustment.

[0099] Optionally, based on the click operation and / or touch measurement command in the test measuring instrument, the user's required test measurement scenario is obtained, including: based on the click operation and / or touch measurement command of the test measuring instrument used to activate the menu setting function of the target direction measurement line in multiple target function windows, the user's required multi-window parameter setting scenario is obtained; the current adjustment parameters matching the test measurement scenario are obtained, and a pairing relationship is established between the current adjustment parameters and the first knob and / or the second knob in the test measuring instrument, including: obtaining all candidate windows matching the multi-window parameter setting scenario as current window parameters, and obtaining the quantity value of the current window parameters; according to the preset window priority, the first priority window parameter is obtained from all current window parameters, and the horizontal measurement line adjustment parameters and vertical measurement line adjustment parameters matching the first priority window parameters are obtained; according to the preset adjustment parameter priority, the horizontal measurement line... The adjustment parameters and vertical measurement line adjustment parameters are obtained by acquiring the first priority parameter and the second priority parameter, respectively. A pairing relationship is established between the first priority parameter and the first knob, and a pairing relationship is established between the second priority parameter and the second knob. It is determined whether the number of remaining current window parameters is less than 1. If not, the second priority window parameter is acquired from all current window parameters, and the horizontal measurement line adjustment parameter and vertical measurement line adjustment parameter that match the second priority window parameter are acquired. The process returns to execution and, according to the preset adjustment parameter priority, the first priority parameter and the second priority parameter are acquired from the horizontal measurement line adjustment parameter and the vertical measurement line adjustment parameter, respectively. A pairing relationship is established between the first priority parameter and the first knob, and a pairing relationship is established between the second priority parameter and the second knob. If yes, the pairing relationship between the current adjustment parameter and the first knob and / or the second knob in the test measuring instrument is completed.

[0100] In this scenario, multiple windows are selected for parameter setting, where the number of target windows whose parameters are to be adjusted is multiple. All candidate windows can be multiple target windows displayed on the screen for parameter adjustment. Window priority refers to the order of priority for each window. The first priority window parameter is the parameter of the current window with the highest priority. The second priority window parameter is the parameter of the current window with the second highest priority.

[0101] Understandably, when there are multiple values ​​for the current window parameter in all candidate windows, it is necessary to adjust them according to the priority of each window parameter in order to complete the adjustment of different parameters in each window, thereby realizing the measurement and adjustment of multiple current window parameters.

[0102] like Figure 2eThe diagram shows the structure of a test measuring instrument where a pair of knobs control the parameter adjustment interface of multiple windows according to window priority. The first knob 101 is located on the far right of the instrument, and the second knob 102 is below it. The middle section is the display screen 2 (current window parameter 2, i.e., window 2). The cursor measurement function, as well as the horizontal measurement line adjustment parameters 201 and 202, can be selected by pressing the knobs or touching the display screen. The current window parameter 3 (window 3) is located in the upper right corner of the display screen, and the current window parameter 4 (window 4) is located in the lower right corner.

[0103] Furthermore, based on the click operations and / or touch measurement commands of the test measuring instrument used to activate the menu setting function of the target direction measurement line in multiple target function windows, the user's required multi-window parameter setting scenario is obtained. Specifically, in Figure 2e The system displays multiple windows with multiple functions activated, including waveform cursor measurement in window 2, waveform calculation in window 3, and waveform calculation in window 4. The control system pairs the parameters monitored by the first knob 101 and the second knob 102 according to fixed window priorities or user-defined priorities. The rotation of the first knob 101 and the second knob 102 controls the movement of the horizontal measurement line adjustment parameter 01 or the vertical measurement line adjustment parameter 202, respectively.

[0104] Correspondingly, the waveform position in window 2 or window 3 can be moved. This allows the test instrument to adjust parameters across multiple windows using a pair of knobs. Thus, when controlling multiple windows and parameters, the pair of knobs can not only control parameters within the same window according to priority, but also control parameters in different windows separately, offering extremely high operational flexibility.

[0105] Optionally, determining the adjustment value of the target adjustment parameter based on the operation description information fed back by the first knob or the second knob includes: obtaining initial adjustment parameters, wherein the operation description information includes clockwise rotation, counterclockwise rotation, the step value of adjusting the first knob and / or the second knob, and the rotation speed; calculating a step coefficient based on the rotation speed of the first knob and / or the second knob, and multiplying the step coefficient by the step value to calculate a weighted step value; determining whether the first knob and / or the second knob are rotated clockwise, and if so, adding the weighted step value to the initial adjustment parameters to obtain the adjustment value of the target adjustment parameter; if not, subtracting the weighted step value from the initial adjustment parameters to obtain the adjustment value of the target adjustment parameter.

[0106] The initial adjustment parameter can be the initial value of the current adjustment parameter. The step value can be the actual scale value of the current adjustment parameter when the knob is rotated. The rotation speed can be the speed at which the user rotates the knob. The step coefficient can be a weighting coefficient describing the step value, which can be calculated based on the rotation speed; specifically, the greater the user's rotation speed, the larger the corresponding step coefficient. The weighted step value can be the final step value obtained by weighting the actual step values.

[0107] Understandably, by adjusting the knob coarsely and finely, the target adjustment value can be achieved accurately and quickly, thereby improving the efficiency of parameter adjustment.

[0108] For example, suppose the current adjustment parameter 1 is adjusted using the first knob. First, the initial adjustment parameter A corresponding to the current adjustment parameter 1 needs to be obtained. The control system receives the operation description information of the first knob, which is clockwise rotation, step value B, and rotation speed a.

[0109] Specifically, the step coefficient b can be calculated based on the rotation speed of the first knob. Next, the weighted step value b*B can be calculated. Then, it needs to be determined whether the first knob is rotating clockwise. Since the operation description information of the first knob indicates that it is rotating clockwise, the adjustment value of the target parameter can be calculated as A+b*B.

[0110] Alternatively, assuming the first knob is rotated counterclockwise, the adjustment value of the target adjustment parameter can be calculated as Ab*B.

[0111] The advantage of this setup is that by acquiring the operation description information corresponding to the knob, the adjustment value of the target adjustment parameter can be calculated based on the initial adjustment parameter of the current adjustment parameter. When the target adjustment parameter corresponding to the current adjustment parameter is large, the target adjustment value can be quickly reached by weighting the step values ​​through the rotation speed, thereby improving the efficiency of parameter adjustment.

[0112] The technical solution provided by this invention obtains the user's required test and measurement scenario based on the click operation in the test and measurement instrument, and sends the screen display content matching the test and measurement scenario to the display screen for display; obtains the current adjustment parameter matching the test and measurement scenario, and establishes a pairing relationship between the current adjustment parameter and the first knob and / or the second knob; determines the adjustment value of the target adjustment parameter based on the operation description information fed back by the first knob or the second knob, and feeds back the updated display content according to the adjustment value to the display screen for updating display. By using a pair of knobs to adjust parameters in the test and measurement instrument, or using a pair of knobs alternately to control different parameter adjustments, or using a pair of knobs alternately to control the virtual keyboard to achieve parameter adjustment, a pair of knobs can not only control parameters in the same window according to priority order, but also control parameters in different windows separately. The operation flexibility is very high, realizing the reuse and maximization of a pair of knobs, enabling the adjustment of multiple parameters, enriching the testing functions of the test and measurement instrument, thereby improving the accuracy of parameter adjustment, operational efficiency, and user convenience.
