Detailed Description
The present invention is further described in detail below with reference to the attached drawings so that those skilled in the art can implement the invention by referring to the description text.
It is to be noted that the experimental methods described in the following embodiments are all conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified.
The vector network analyzer is a kind of electromagnetic wave energy testing equipment, it can measure various parameter amplitudes of single-port network or two-port network, and can measure phase position, the vector network analyzer can use Smith chart to display measured data, it is more convenient for engineering application and debugging.
The vector network analyzer generally has a GPIB interface, can be in communication connection with an upper computer through a GPIB/USB interface conversion card, and generally supports an SCPI protocol, so that the upper computer can control the vector network analyzer through an SCPI instruction.
Based on the above knowledge, as shown in fig. 1, the present invention provides an automatic test method for a vector network analyzer, which is applied to an upper computer, and the automatic test method for the vector network analyzer is described below by taking an example of using the vector network analyzer to test a maximum value and a frequency point of a standing wave at two ends of a radio frequency cable, and a minimum value and a frequency point of an insertion loss at two ends.
The automatic test method of the vector network analyzer comprises the following steps:
s1: sending an instrument initialization instruction to a vector network analyzer, and simultaneously acquiring a test form to be filled in a bookmark mode, wherein the test form at least comprises test result lattices of a plurality of tested objects to be filled in, the test result lattices of the plurality of tested objects are respectively positioned in different rows in the test form, each tested object has a unique serial number, and the serial number of each tested object has a corresponding relation with the row number of the tested object in the test form;
the vector network analyzer supports the SCPI protocol, so that an instrument initialization instruction automatically sent to the vector network analyzer can be set to be the SCPI instruction, the vector network analyzer is initialized through the VXI driving function after receiving the instrument initialization instruction, and if the initialization is successful, a return value is 0.
The bookmark is commonly used for marking a position designated by a user in the word, the position of each cell in the form can be obtained by obtaining a test form to be filled in a bookmark form, the style of the test form is shown in fig. 2, a tested object is a radio frequency cable, each radio frequency cable corresponds to a unique serial number, simultaneously, the test result grid of each radio frequency cable and the serial number of the radio frequency cable are in the same row, the row number of the serial number of the radio frequency cable belongs to the position attribute of the cell, and therefore the row number of the test result grid of the radio frequency cable in the test form can be determined by knowing the serial number of each radio frequency cable through the relation of the bookmark.
S2: a, receiving a serial number of a tested object input by a user, and determining a row of a test result lattice of the tested object according to the serial number of the tested object; or b, receiving a cancel instruction input by a user to terminate the test;
specifically, as shown in fig. 3, the process of receiving the serial number of the measured object input by the user includes: and acquiring the radio frequency cable serial number input by the user through an InputBox function.
In the VBA language, the InputBox function is used for popping up a dialog box, prompting a user to input characters, returning the characters input by the user after the user presses a confirm button for inputting the characters, and returning to be null if a cancel button is pressed.
In the test table, the test result lattice of each radio frequency cable is in the same row with the serial number of the radio frequency cable, so that the serial number of the tested radio frequency cable input by a user is received, and the row of the test result lattice of the tested radio frequency cable can be immediately positioned.
Therefore, if the user inputs the serial number of the tested cable, the serial number is confirmed to be correct, and the confirming button is pressed, the row where the test result grid of the tested radio frequency cable is located can be immediately positioned. However, if the user presses the cancel button, it may indicate that the user has found an error and needs to stop the test, so that when the user returns to null, a jump-out test program may be set to terminate the test.
S3: a, receiving a determination test instruction input by a user, and sending an S parameter switching instruction to a vector network analyzer so that the vector network analyzer automatically completes the test of a tested object and obtains a signal fed back by the vector network analyzer for completing the test of a single tested object; or b, receiving a cancel instruction input by a user to terminate the test;
specifically, as shown in fig. 4, the process of receiving the test instruction input by the user includes: and acquiring a determined test instruction input by a user through the MsgBox function.
In the VBA language, the MsgBox function is used for popping up a dialog box, waiting for a user to click a button, returning an integer value to indicate which button the user clicks, wherein if the user clicks a determined button, the returned integer value is 1, and if the user clicks a cancel button, the returned integer value is 2.
Therefore, when the return value is 1, the S parameter switching instruction can be automatically sent to the vector network analyzer, so that the vector network analyzer automatically completes the test of the radio frequency cable, and a signal fed back by the vector network analyzer and used for completing the test of the single radio frequency cable is obtained; when the return value is 2, a jump-out test program can be set, and the test is terminated.
And the vector network analyzer supports the SCPI protocol, so that an S parameter switching command automatically sent to the vector network analyzer can be set to be an SCPI command, and after the vector network analyzer receives the S parameter switching command, the S parameter S11 and S22 are switched, a standing wave maximum value command is set, and S parameters S12 and S21 are switched, and an insertion loss minimum value command is set.
S4: sending a query instruction to the vector network analyzer to obtain a test result of the object to be tested, and automatically writing the test result of the object to be tested into a test result grid of the object to be tested based on the step S2 a;
specifically, the process of sending the query instruction to the vector network analyzer based on step S3a to obtain the test result of the radio frequency cable includes: and sending a test result query instruction to the vector network analyzer through the viVPrintf writing function, reading the test result through the viVScaf reading function, and adjusting the data format and decimal digits of the test result through the format function.
In the embodiment, the test result display format of the table is 2 decimal places, so that each newly obtained test result is adjusted before filling the table. When the insertion loss test result is less than 1dB, a number 0 is written into the cell before writing into the cell, and for the case that the test result only has a 1-bit decimal, a function str (0) instruction is added, for example: the instrument reads a value of.4, when writing in a cell, firstly writing a number 0 in the cell, and then adding a function str (0) instruction behind the test result, so that the cell displays 0.40. And when the insertion loss test result is greater than 1dB, if the test result only has 1-bit decimal, adding a function str (0) instruction, otherwise, not adding. The processing method for writing the standing wave test result is the same as that for the insertion loss test result.
The process of automatically writing the test result of the radio frequency cable into the radio frequency cable test result grid comprises the following steps: and determining the row number of the radio frequency cable test result grids to be filled through the cell attribute of the test table, and automatically writing the test result of the tested object into the corresponding test result grid of the tested object through setting the range.
Because each radio frequency cable needs to fill in 8 test result grids which belong to different test indexes respectively, and the 8 test result grids are respectively positioned in different columns of the same row in the test table, the method for automatically writing the test result of the radio frequency cable into the test result grid of the radio frequency cable is used for each test result grid once until the 8 test result grids in one row are filled.
And S5, repeatedly executing S2a-S3a-S4 until all the measured objects are measured.
Specifically, the operations S2a-S3a-S4 can be repeatedly executed through the VBA loop statement until all the objects to be tested are tested.
In the embodiment, the upper computer can be connected with the vector network analyzer through the VBA language and the interface conversion card, various instructions are sent to the vector network analyzer through the upper computer, and the automatic test method of the vector network analyzer is implemented through the program preset in the upper computer, so that the automatic input of the test result is realized, the workload of manual input is reduced, the manual input error is avoided, and the test efficiency of the vector network analyzer used by a user is improved. In the test process, the user inputs information each time and has two choices of determining and canceling, so that when the user finds that the test has a problem, the user can stop the test by clicking a cancel button, and the problem is prevented from continuously expanding.
In another embodiment, the steps S1 and S2 further include: a1: a, receiving and storing the total amount of a measured object input by a user; or b, receiving a cancel instruction input by a user to terminate the test;
specifically, as shown in fig. 5, the process of receiving and storing the total amount of the measured object input by the user includes: and acquiring the total amount of the radio frequency cables input by a user through an InputBox function.
The input box function is introduced previously, and only the execution operation of the upper computer after the user clicks to confirm or cancel is described here, because the input box function returns the characters input by the user after the user presses the confirm button, the total amount of the radio frequency cables input by the user can be set and stored, so as to be convenient for the subsequent judgment of whether all the radio frequency cables are tested, and when the user presses the cancel button, a jump-out test program can be set to terminate the test.
The process of determining whether all the objects to be measured have been measured in step S5 includes: and recording the repeated execution times of the steps S2a-S3a-S4, and when the repeated execution times of the steps S2a-S3a-S4 reach the total amount of the measured object, all the measured objects are measured.
The number of times that steps S2a-S3a-S4 are repeatedly executed may be set as a variable, when steps S2a-S3a-S4 are executed once, a self-increment operation is performed on the repeatedly executed variable, the result of each self-increment operation of the repeatedly executed variable is compared with the total number of the radio frequency cables, when the result of the repeatedly executed variable is the same as the total number of the radio frequency cables, it indicates that all the radio frequency cables are tested, and if the result is less than the total number of the radio frequency cables, steps S2a-S3a-S4 are continuously executed repeatedly.
In another embodiment, the steps S1 and S2 further include: a2: a, receiving and storing a test index threshold value input by a user; or b, receiving a cancel instruction input by a user to terminate the test;
the object to be tested is a radio frequency cable, the test result comprises the maximum value and the maximum value frequency point of the standing wave at the two ends of the radio frequency cable, and the minimum value frequency point of the insertion loss at the two ends, so the test index threshold comprises the standing wave index and the insertion loss index.
Specifically, as shown in fig. 6 to 7, the process of receiving and storing the test index threshold value input by the user includes: and obtaining a standing wave index input by a user through an InputBox function, and obtaining an insertion loss index input by the user through the InputBox function. The input box function returns the characters input by the user after the user presses the determining button, so that the standing wave index and the insertion loss index input by the user can be set and stored, whether the test result meets the index requirement or not can be conveniently judged in the following process, and when the user presses the cancel button, a jump-out test program can be set, and the test is terminated.
Step S5 is followed by: a3, comparing the test result of the tested object with the test index threshold value, and displaying the test result which does not meet the requirement of the test index threshold value in a test table by red characters.
If, then, else and End if sentences in the VBA language can be adopted to execute the operation of comparing the test result of the tested object with the threshold value of the test index, and the test result higher than the standing wave index and the test result larger than the insertion loss index are displayed in the test form by using a red font (the color of the original font is black), so that a user can distinguish which radio frequency cables are unqualified at a glance, and the working efficiency is greatly improved.
If the first test result is doubtful, the second test can be carried out, the second test result can be written in the table to cover the first test result, if the first test result is abnormal, the first test result is displayed in red font, and if the second test result is normal, the second test result is still displayed in black font.
In another embodiment, the steps S1 and S2 further include: a4, calling dll driver through GetTickCount function to set the delay time of the vector network analyzer.
In the VBA language, the GetTickCount function returns the number of milliseconds elapsed from the start of the operating system, so that the delay time of the vector network analyzer is set by calling dll drive by using a return value obtained by the GetTickCount function, and the synchronous work of the upper computer and the vector network analyzer can be kept.
