[0090] Further, the time corresponding to the cursor and the parameter measurement value are displayed simultaneously in the screen.

[0091] Reference Figure 2 , Figure 2 The flowchart of the first embodiment of the cursor measurement method of the present application.

[0092] In the present embodiment, an embodiment of the cursor measurement method is provided. It should be noted that although a logical sequence is shown in the flowchart, in some cases, the steps shown or described herein can be performed in a sequence different from that shown herein.

[0093] In step S10, the angle corresponding to each marker is determined, and a horizontal parameter of each marker in the horizontal direction of the oscilloscope relative to the reference line in the screen is acquired.

[0094] In step S20, a horizontal parameter between the cursor in the screen and the reference line is acquired.

[0095] It should be noted that in the present embodiment, the oscilloscope includes a screen, and each horizontal grid in the screen represents a time base. When the time base decreases, the waveform will be enlarged.

[0096] Specifically, for example, the time base position of the oscilloscope display screen is preset, and a plurality of marks are determined in the horizontal direction of the oscilloscope, and the horizontal parameters of each mark and the reference line of the display screen are determined, and the angles corresponding to each mark are obtained. In addition, the horizontal parameter between the cursor and the reference line is determined after the cursor is opened.

[0097] It should be noted that in the present embodiment, the number of marks is preset to be 2, and in the present embodiment, each mark is not specifically limited, and the mark can be a straight line, a triangular symbol, a line segment, a figure, and a point, etc.

[0098] Step S30, based on the horizontal parameter of each mark relative to the reference line in the display screen, the angles corresponding to the plurality of marks, and the horizontal parameter between the cursor and the reference line, the parameter measurement value of the cursor at the preset target position is obtained.

[0099] It should be noted that in the present embodiment, when the parameter of a specific position needs to be measured, the cursor can be moved to the position, and the parameter at the position is measured according to the preset calculation rule.

[0100] Specifically, for example, as shown in the oscilloscope display screen of Figure 3 After obtaining the horizontal parameter of each mark relative to the reference line of the display screen, the angles corresponding to the plurality of marks, and the horizontal parameter between the cursor and the reference line, the parameter at the target position of the cursor is measured based on the above parameters according to the preset parameter calculation rule.

[0101] It should be noted that in the present embodiment, if the parameter to be measured is an angle, then the parameter calculation rule at this time is:

[0102] ρ=(c-a)*(β-α) / ΔM+α

[0103] Wherein, ρ is the angle at the position of the cursor, c is the horizontal parameter between the cursor and the reference line, a is the horizontal parameter of the mark relative to the reference line of the display screen, α and β are the angles corresponding to the cursor, and ΔM is the relative parameter between each mark. In addition, the parameter to be measured can be other physical quantities besides the angle, such as the period, etc.

[0104] Further, the step of "determining the angle corresponding to each mark, and obtaining the horizontal parameter of each mark relative to the reference line in the display screen in the horizontal direction of the oscilloscope" in the above step S10 comprises:

[0105] In step S101, the first angle corresponding to the first marker and the second angle corresponding to the second marker are determined, and the first horizontal parameter and the second horizontal parameter of the first marker and the second marker relative to the reference line are determined.

[0106] It should be noted that in the present embodiment, two markers are pre-set, including a first marker and a second marker.

[0107] Specifically, for example, the first marker is determined, and the first horizontal parameter of the first marker relative to the reference line of the display screen is obtained; at the same time, the second marker is determined, and the second horizontal parameter of the second marker relative to the reference line of the display screen is obtained, so as to determine the relative parameter between the first marker and the second marker based on the first horizontal parameter and the second horizontal parameter.

[0108] Further, the reference line includes a vertical line based on the first marker, a vertical line based on the second marker, a screen edge of the display screen, a vertical center line of the display screen, and a vertical line at any position on the display screen, and the horizontal parameter includes pixels, distance, time, and proportion.

[0109] In the present embodiment, the reference line is not specifically limited, and the reference line can be a vertical line of the marker, a screen boundary of the display screen of the oscilloscope, a vertical center line in the display screen, and a vertical line at any position on the display screen. In the present embodiment, the horizontal parameter of the reference line is also not specifically limited, and the horizontal parameter is not limited to distance, but can also be pixel, time, and proportion.

[0110] Further, in the above step S10, "obtaining the horizontal parameter of each of the markers in the horizontal direction of the oscilloscope relative to the reference line in the display screen" can further include:

[0111] In step S102, when the marker is not in the display screen, the marker is moved into the display screen, and the horizontal parameter of the translated marker relative to the reference line is determined, so as to obtain the parameter measurement value of the cursor at the preset target position according to the horizontal parameter, the angle, the horizontal parameter between the cursor and the reference line.

[0112] It should be noted that in the present embodiment, when the marker is not in the display screen, the user can translate the marker into the screen by translating the waveform, in which case the horizontal parameter of the translated marker relative to the reference line can be further determined, and then according to the horizontal parameter, the angle of each marker, and the horizontal parameter between the opened cursor and the reference line, the parameter calculation rule

[0113] p = (c-a)*(β-α) / ΔM+α

[0114] Determine the parameter measurement value at the position of the cursor.

[0115] Further, in the step S10, the "obtaining the horizontal parameter of each mark in the horizontal direction of the oscilloscope relative to the reference line in the display screen" can include:

[0116] In step S103, the waveform in the display screen is scaled, the horizontal parameter of the scaled mark relative to the reference line is determined based on the proportional relationship of the waveform of the oscilloscope before and after scaling, and the parameter measurement value of the cursor at the preset target position is obtained according to the horizontal parameter, the angle, and the horizontal parameter between the cursor and the reference line, wherein the proportional relationship is determined according to the first time base position before scaling and the second time base position after scaling of the oscilloscope.

[0117] After the user scales up or down the waveform in the oscilloscope, the horizontal parameter of the scaled mark relative to the reference line can be further determined to determine the parameter measurement value at the position of the cursor according to the horizontal parameter, the angle corresponding to each mark, and the horizontal parameter between the opened cursor and the reference line.

[0118] It should be noted that in the present embodiment, regardless of whether the user performs a translation mark operation, a scaling waveform operation, or various combination operations such as translation scaling and scaling translation, the calculation rule of the parameter measurement value at the position of the cursor follows the following principles:

[0119] ρ=(c-a)*(β-α) / ΔM+α

[0120] In the present embodiment, the time base position of the oscilloscope display screen is preset, the first mark and the second mark are determined in the horizontal direction of the oscilloscope, and the first horizontal parameter of the first mark relative to the reference line of the display screen and the second horizontal parameter of the second mark relative to the reference line of the display screen are obtained, and the angle corresponding to each mark is obtained. In addition, the reference line of the display screen is determined, the first distance between the opened cursor and the reference line is determined, and then the parameter at the target position of the cursor is measured based on the above-mentioned parameters according to the preset parameter calculation rule.

[0121] Compared with the prior art which cannot accurately measure the angle and physical parameters such as period at a specific position in a period, in the present application, two marks are first preset, and then the corresponding horizontal parameters of each mark and the angle corresponding to each mark are obtained, and then the parameter at the target position of the cursor is measured according to the preset parameter calculation rule. Therefore, the present application can accurately measure the physical parameters at any position of the cursor, which not only improves the use efficiency of the oscilloscope, but also improves the user experience.

[0122] Further, based on the first embodiment of the cursor measurement method of the present application, a second embodiment of the cursor measurement method of the present application is provided.

[0123] The main difference between the present embodiment and the first embodiment is that, in the present embodiment, the cursor measurement method of the present application further comprises:

[0124] Step S40, after the waveform in the display screen is enlarged, if the first marker is not in the display screen at this time, the first marker is translated into the display screen by moving the waveform, and a first translation parameter is determined;

[0125] Step S50, based on the first translation parameter, the first horizontal parameter, the second horizontal parameter, the first time base position and the second time base position, a third horizontal parameter and a fourth horizontal parameter of the first marker and the second marker in the screen relative to the reference line are determined;

[0126] Further, the step S30 can comprise:

[0127] Step S301, based on the third horizontal parameter and the fourth horizontal parameter, a first relative parameter between the first marker and the second marker in the screen is obtained, and a parameter measurement value of the cursor at the preset target position is obtained according to the first relative parameter, the horizontal parameter between the cursor and the reference line, the third horizontal parameter and the angle.

[0128] It should be noted that, in the present embodiment, as shown in the oscilloscope display screen of each parameter, Figure 4 the user can enlarge or reduce the waveform by adjusting the time base position of the oscilloscope. In the embodiment, the time base position includes S1 and S2, when the time base position is S1, the first marker and the second marker are both in the display screen, and when the time base position is S2, the first marker and the second marker are not in the display screen.

[0129] Specifically, for example, as shown in the oscilloscope display screen of each parameter, Figure 5 when the first marker M1 is not in the display screen, the time base position at this time is S2, the first marker is translated into the display screen to obtain the first translation parameter x1, as shown in the oscilloscope display screen of each parameter, Figure 5 at this time, the third horizontal parameter a' of the first marker in the screen relative to the reference line is:

[0130] a' = a * S1 / S2 + x1

[0131] wherein a is the first horizontal parameter of the first marker relative to the reference line of the display screen before translation when the time base position is S1. At this time, the fourth horizontal parameter b' of the second marker relative to the reference line is:

[0132] b' = b * S1 / S2 + x1

[0133] wherein b is a second horizontal parameter of the second marker relative to a reference line of the display screen when the time base position is S1. At this time, a first relative parameter AM1 between the first marker and the second marker after the translation is:

[0134] AM1 = b' - a' = S1 * (b - a) / S2

[0135] At this time, a first distance between the cursor and the reference line is c, and a parameter measurement value p1 of the cursor at the preset target position is:

[0136] p1 = (c - a') * (b - a) / AM1 + a

[0137] wherein a is an angle corresponding to the first marker, and b is an angle corresponding to the second marker.

[0138] Further, after the step S50 of "determining third and fourth horizontal parameters of the first marker and the second marker in the screen relative to the reference line, respectively", the method further comprises:

[0139] a step S60 of obtaining a first adjustment parameter and finely adjusting the first marker in the screen according to the first adjustment parameter to obtain a fifth horizontal parameter;

[0140] Further, the step S30 further comprises:

[0141] a step S302 of obtaining a second relative parameter between the first marker after the fine adjustment and the second marker based on the fifth horizontal parameter and the fourth horizontal parameter, and obtaining a parameter measurement value of the cursor at the preset target position according to the second relative parameter, a horizontal parameter between the cursor and the reference line, the fifth horizontal parameter, and the angle.

[0142] It should be noted that in the embodiment, the first marker M1 is translated into the display screen, and the position of the first marker M1 can be further finely adjusted.

[0143] Specifically, for example, as shown in the oscilloscope display screen, Figure 5 the third horizontal parameter a' of the first marker M1 is adjusted according to the first adjustment parameter a to obtain a fifth horizontal parameter a' + a after the fine adjustment, and at this time, a second relative parameter AM2 between the second marker M2 and the first marker M1 after the fine adjustment is:

[0144] AM2 = S1 * (b - a) / S2 - a

[0145] At this time, the angle measurement value of the cursor at the preset target position is ρ2:

[0146] ρ2=(c-a'-Δa)*(β-α) / ΔM2+α

[0147] It should be noted that in the present embodiment, when the user actually uses the oscilloscope, the following situations may occur: all the marks are in the display screen, only one is in the display screen, all the marks are not in the display screen, or the user does not finely adjust the position of the marks but directly calculates the parameters at the position of the cursor. In any case, the parameter calculation rule at the target position of the cursor is universally applicable.

[0148] In the present embodiment, when the first mark deviates from the display screen, the deviated first mark can be translated back to the display screen, and the parameters at the position of the cursor are calculated based on the translation parameters of the first mark, or the cursor is finely adjusted, and the parameters at the position of the cursor are calculated again based on the finely adjusted cursor. The parameter calculation rule at the target position of the cursor is universally applicable. Therefore, the present application realizes flexible calculation of the parameters at the target position of the cursor, thereby improving the efficiency of the user when operating through the oscilloscope and improving the user experience.

[0149] Further, based on the first and second embodiments of the present application, a third embodiment of the present application is proposed.

[0150] The difference between the present embodiment and the above-mentioned second embodiment is that in the present embodiment, the present application further comprises:

[0151] Step S70, after the waveform in the display screen is amplified, if the second mark is not in the display screen at this time, the second mark is translated to the display screen by moving the waveform, and a second translation parameter is determined;

[0152] Step S80, based on the fifth horizontal parameter and the second translation parameter, a sixth horizontal parameter of the finely adjusted first mark relative to the reference line of the display screen is determined, and based on the fourth horizontal parameter and the second translation parameter, a seventh horizontal parameter of the second mark in the screen relative to the reference line is determined;

[0153] Further, the above-mentioned step S30 further comprises:

[0154] Step S303, obtaining a third relative parameter between the fine-adjusted first mark and the translated second mark based on the sixth horizontal parameter and the seventh horizontal parameter, and obtaining a parameter measurement value of the cursor at the preset target position according to the third relative parameter, a horizontal parameter between the cursor and the reference line, the sixth horizontal parameter, and the angle.

[0155] It should be noted that in the present embodiment, the first mark M1 deviating from the display screen has been translated into the display screen by the first adjustment parameter Δa mentioned in the second embodiment, but at this time the second mark M2 is still outside the display screen, so the second mark M2 can also be translated into the display screen by the second adjustment parameter Δb.

[0156] Specifically, for example, as shown in the oscilloscope display screen of each parameter, when the second mark M2 is not in the display screen, the time base position at this time is S2, the second mark is translated into the display screen to obtain a second translation parameter x2, and the seventh horizontal parameter b" of the translated second mark relative to the reference line at this time is: Figure 6

[0157] b″=b′+x2=b*S1 / S2+x1+x2

[0158] At this time, the sixth horizontal parameter a" of the fine-adjusted first mark relative to the reference line is:

[0159] a″=a′+Δa+x2=a*S1 / S2+Δa+x1+x2

[0160] Further, the third relative parameter ΔM3 between the translated second mark and the fine-adjusted first mark is:

[0161] ΔM3=b″-a″=S1*(b-a) / S2-Δa

[0162] At this time, the first distance between the cursor and the reference line is c, and then the angle measurement value ρ1 of the cursor at the preset target position is:

[0163] ρ3=(c-a″)*(β-α) / ΔM3+α

[0164] Further, after the step S80 of "determining the seventh horizontal parameter of the second mark in the screen relative to the reference line based on the fourth horizontal parameter and the second translation parameter", it further includes:

[0165] Step S90, obtaining a second adjustment parameter, and fine-adjusting the second mark in the screen according to the second adjustment parameter to obtain an eighth horizontal parameter;

[0166] Further, the above step S30 further includes:​

[0167] Step S304: Based on the eighth level parameter and the sixth level parameter, obtain the fourth relative parameter between the finely adjusted first mark and the finely adjusted second mark, and obtain the parameter measurement value of the cursor at the preset target position according to the fourth relative parameter, the horizontal parameter between the cursor and the reference line, the sixth level parameter, and the angle.

[0168] It should be noted that, in this embodiment, after the second mark M2 is moved onto the display screen, the position of the second mark M2 can be further finely adjusted.

[0169] Specifically, for example, such as Figure 6 The parameters shown on the oscilloscope display are adjusted according to the second adjustment parameter Δb. The sixth level parameter b” of the second mark M2 is adjusted to obtain the eighth level parameter b”+Δb. At this time, the fourth relative parameter ΔM4 between the first mark M1 and the second mark M2 after fine adjustment is:

[0170] ΔM4=S1*(ba) / S2+Δb-Δa

[0171] It should be noted that, in this embodiment, as Figure 7 After fine-tuning the second marker after translation, the parameters displayed on the oscilloscope screen can be moved to the desired measurement position to measure the relevant physical quantities. At this time, the angle measurement value ρ4 of the cursor at the preset target position is:

[0172] ρ4=(ca″)*(β-α) / ΔM4+α

[0173] Furthermore, the time corresponding to the cursor and the parameter measurement value are simultaneously displayed on the display screen.

[0174] Specifically, for example, such as Figure 8 The oscilloscope display shows the time corresponding to the cursor's position, as well as the specific parameters at the target position obtained according to the parameter calculation rules. This allows users to observe the measurement results on the oscilloscope at any time when measuring parameters at any position on the waveform, thus improving the user experience.

[0175] In the embodiment, when the second mark is offset from the display screen, the offset second mark can be retranslated back to the display screen, and the parameter at the position of the cursor is calculated based on the translation parameter of the second mark, or the second mark after translation is finely adjusted, and the parameter at the position of the cursor is calculated again based on the finely adjusted mark. The parameter calculation rule at the target position of the cursor is also universally applicable. Therefore, the application realizes flexible calculation of the parameter at the target position of the cursor, and simultaneously displays the corresponding time and parameter measurement value at the position of the cursor on the display screen, improves the efficiency of the user when operating the oscilloscope, and improves the user experience.
