[0002] Tunable filters can improve communication quality and enhance electromagnetic compatibility between internal communication system devices and other subsystems. They also offer continuously adjustable frequency. Tunable filters can be divided into the filter body and the DC voltage transmission (or mechanical transmission) and control system.

Each tunable narrowband filter has its own unique mapping between frequency and encoded voltage (or angle).

[0036] S5. Send the coded data acquisition instruction corresponding to the current frequency point to the multi-coupler;

[0037] S6. Determine whether the collection of coded data corresponding to all frequency points is completed. If not, adjust to the next frequency point and return to step S3; if so, complete the collection of coded data for the adjustable filter.

[0038] From the above description, it can be seen that the beneficial effects of the present invention are:

[0039] The present invention provides a fully automatic coding data acquisition method for an adjustable filter, which specifically includes sending a radio frequency switch path setting selection instruction and a channel number selection instruction to a multi-way coupler; obtaining the center frequency and bandwidth parameters set by a vector network analyzer; sending a voltage step instruction or an angle step instruction to the multi-way coupler and simultaneously obtaining the position of a bandpass filter waveform; judging whether the position of the bandpass filter waveform is at the center position, and if not, again sending the voltage step instruction or the angle step instruction to the multi-way coupler until the bandpass filter waveform is at the center position; sending a coding data acquisition instruction corresponding to the current frequency point to the multi-way coupler; judging whether the coding data acquisition corresponding to all frequency points is completed, and if so, completing the coding data acquisition of the adjustable filter. Compared with the traditional multi-coupler debugging (manual collection of coding data) method, the fully automatic coding data collection method and system in the present invention solves the original technical problems, and the debugging is fully automatically controlled by the computer, and the test data is fully automatically processed by the software, which improves the testing and debugging efficiency.

[0040] Furthermore, in step S4, the method for determining whether the position of the bandpass filter waveform is at the center position is:

[0044] As can be seen from the above description, the above method serves as a basis for determining whether the position of the bandpass filter waveform is at the center. In other words, if the difference between the left and right insertion loss values ​​is less than a first preset threshold, and the first preset threshold is set to a relatively small value, then once the difference is less than the relatively small value, it can be determined that the left and right insertion loss values ​​are nearly identical.

[0045] Further, it is determined whether the difference is less than a first preset threshold. If so, it is determined that the position of the bandpass filter waveform is at the center position, specifically:

[0055] S5. Send the coded data acquisition instruction corresponding to the current frequency point to the multi-coupler;

[0056] S6. Determine whether the collection of coded data corresponding to all frequency points is completed. If not, adjust to the next frequency point and return to step S3; if so, complete the collection of coded data for the adjustable filter.

[0067] As can be seen from the above description, based on the above judgment, further combined with the size of the left-end insertion loss value and the right-end insertion loss value, that is, if the left-end insertion loss value and the right-end insertion loss value are both not greater than the second preset threshold, it can be further determined that the position of the bandpass filter waveform is at the center position.

[0068] Furthermore, when the processor executes the computer program, the following steps are specifically implemented: the second preset threshold is 2dB.

[0069] Please refer to Figure 1 、 Figures 3 to 5 , embodiment 1 of the present invention is:

[0070] The present invention provides a fully automatic encoding data acquisition method for an adjustable filter, comprising the following steps:

[0071] S1, the multi-coupler f0 code acquisition system sends the RF switch path setting selection instruction and the channel number selection instruction to the multi-coupler;

[0072] In this embodiment, the multi-coupler is provided with 5 channels, namely channel 1#, channel 2#, channel 3#, channel 4# and channel 5#. Channel 1# is used to be electrically connected to the RF routing controller, channel 2# is used to be electrically connected to the voltage (angle) controller, channel 3# is used to be electrically connected to the channel number selector, channel 4# is used to be electrically connected to the voltage (angle) data storage device, and channel 5# is used to be electrically connected to the f0 encoding manager on the PC side.

[0073] A vector network analyzer is used to view the filter's bandpass filtering waveform; an RF routing controller is used to control the device's RF switch path. A channel selector is used to select the device channel. A voltage (angle) controller controls the filter's internal varactor diode's internal bias DC voltage (or the mechanical transmission angle of the internal distributed parallel plate capacitor) to control the equivalent capacitance of the varactor diode (or distributed parallel plate). This changes the capacitance and, in turn, the resonant frequency according to the operating voltage step (or angle step), achieving filter tuning. A voltage (or angle) data memory stores encoded data. PC software: f0 (filter center frequency) encoding manager enables editing and processing of collected data.

[0074] S2, the multi-coupler f0 code acquisition system obtains the center frequency and bandwidth parameters set by the vector network analyzer; specifically, Figure 3As shown, in this embodiment, the multicoupler f0 code acquisition system is hosted by a PC host, which establishes a communication connection with a vector network analyzer. The vector network analyzer has a GPIB port, and the PC host connects to the GPIB port of the vector network analyzer via a GPIB-USB acquisition card. The PC host is connected to the automatic test port of the multicoupler via a serial cable. The P1 port of the vector network analyzer is connected to the radio port of the multicoupler, and the P2 port of the vector network analyzer is connected to the antenna port of the multicoupler.

[0075] The function of the multi-coupler f0 coding acquisition system is to send operation instructions to the multi-coupler, including RF switch path setting instructions, channel number selection instructions, voltage step (or angle step) instructions, and data acquisition instructions. The multi-coupler returns the response status of each instruction to the f0 coding acquisition system.

[0076] The interactive data between the multi-coupler f0 coding acquisition system and the vector network analyzer includes: according to the protocol of the instrument programming instruction set, the f0 coding acquisition system sends specific test instructions to the vector network analyzer, and the vector network analyzer sends the actual test data of the multi-coupler's insertion loss (IL) indicator to the f0 coding acquisition system.

[0077] S3, sending a voltage step command or an angle step command to the multi-coupler and simultaneously obtaining the position of the bandpass filter waveform;

[0078] S4, determining whether the position of the bandpass filter waveform is at the center position; if not, sending a voltage step command or an angle step command to the multicoupler again until the bandpass filter waveform is at the center position, and then proceeding to step S5;

[0079] The method for determining whether the position of the bandpass filter waveform is at the center position in step S4 is as follows:

[0080] According to the center frequency and bandwidth parameters obtained in step S2, the corresponding left-end insertion loss value and right-end insertion loss value are obtained;

[0081] Calculate the difference between the left-end insertion loss value and the right-end insertion loss value;

[0082] Determining whether the difference is less than a first preset threshold;

[0083] If so, it is determined whether both the left and right insertion loss values ​​are less than a second preset threshold. If both the left and right insertion loss values ​​are less than the second preset threshold, it is determined that the position of the bandpass filter waveform is at the center. The second preset threshold is 2 dB.

[0084] The above method serves as a basis for determining whether the bandpass filter waveform is at the center. Specifically, if the difference between the left and right insertion loss values ​​is less than a first preset threshold, and the first preset threshold is set to a relatively small value, then once the difference is less than this relatively small value, it can be determined that the left and right insertion loss values ​​are nearly identical. Based on this determination, further combining the magnitude of the left and right insertion loss values, that is, if both the left and right insertion loss values ​​are less than or equal to a second preset threshold, it can be further determined that the bandpass filter waveform is at the center.

[0085] S5. Send the coded data acquisition instruction corresponding to the current frequency point to the multi-coupler;

[0086] S6. Determine whether the collection of coded data corresponding to all frequency points is completed. If not, adjust to the next frequency point and return to step S3; if so, complete the collection of coded data for the adjustable filter.

[0087] The PC interface of the multi-coupler f0 code acquisition system is as follows: Figure 5 As shown, the software cooperates with the hardware to implement the following functions:

[0088] Instrument Settings: Sets the communication port between the PC and the instrument, sends instrument data exchange commands, and performs single operations. Device Settings: Sets the communication port between the PC and the device (multicoupler), sends interactive commands, and performs single operations. Center Frequency f0 Settings: Sets the start and end range and frequency increment of the filter center frequency to be acquired. Bandwidth Settings: Sets the actual known bandwidth m of the filter. Channel Settings: Sets the acquisition channel number and the number of interference channels, and supports locking. Automatic Acquisition: When the Center Frequency f0 option is set to Continuous Acquisition, automatic acquisition supports single-frequency acquisition or continuous multi-frequency acquisition.

[0089] "Instrument Data" displays data transmitted back by the instrument (including information such as insertion loss and its mark frequency value, which is fixed during acquisition), along with information such as the channel number being tested, center frequency f0, and number of interfering channels. This data can be directly copied to Excel for direct editing or summary analysis. "Device Data" displays data transmitted back by the device in the "Device Data" column.

When the processor 2 executes the computer program, the following steps are implemented:

[0093] S2. Obtain the center frequency and bandwidth parameters set by the vector network analyzer;

[0095] S4, determining whether the position of the bandpass filter waveform is at the center position; if not, sending a voltage step command or an angle step command to the multicoupler again until the bandpass filter waveform is at the center position, and then proceeding to step S5;

[0096] S5. Send the coded data acquisition instruction corresponding to the current frequency point to the multi-coupler;

[0097] S6. Determine whether the collection of coded data corresponding to all frequency points is completed. If not, adjust to the next frequency point and return to step S3; if so, complete the collection of coded data for the adjustable filter.

[0100] Calculate the difference between the left-end insertion loss value and the right-end insertion loss value;

[0101] It is determined whether the difference is less than a first preset threshold value. If so, it is determined that the position of the bandpass filtering waveform is at the center position.

[0102] Furthermore, when the processor executes the computer program, the following steps are specifically implemented:

[0103] Determining whether the difference is less than a first preset threshold;

[0104] If so, determine whether the left-end insertion loss value and the right-end insertion loss value are both not greater than the second preset threshold; if the left-end insertion loss value and the right-end insertion loss value are both not greater than the second preset threshold, determine that the position of the bandpass filtering waveform is at the center position.

[0105] Furthermore, when the processor executes the computer program, the following steps are specifically implemented: the second preset threshold is 2dB.
