Abstract

The invention discloses a method and system for testing the phase-shift accuracy of a T / R component based on a trigger function. After each state phase-shift command takes effect, output the measurement synchronous signal to the "external trigger input" port of the vector network analyzer to trigger scanning, monitor the measurement completion signal of the "external trigger ready" port of the vector network analyzer in real time, and send the current vector network analyzer measurement The completion signal is used as the start signal of the next state phase shift instruction. Beneficial effects of the present invention: the number of times of reading the test data of the vector network analyzer by the program control of the industrial computer of the present invention is changed from 64 times to 1 time, which improves the test efficiency.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a method and system for testing the phase-shifting accuracy of a T / R component based on a trigger function. Background technique [0002] Phase shift accuracy is an important index to measure T / R components. At present, it is generally carried out in the way of industrial computer program-controlled state controller and vector network analyzer. The traditional phase-shifting accuracy test system flow is as follows: figure 1 As shown, the program-controlled vector network analyzer inputs the excitation signal to the T / R component, the program-controlled state controller performs a phase-shift operation on the T / R component, the program-controlled vector network analyzer starts scanning, and the program-controlled vector network analyzer obtains a single State shift phasor test data. Repeat to complete the 64-state phase-shift test. [0003] In the above test process, the indust...
