Abstract:

In order to solve the problems such as low test efficiency, poor test stability and weak test traceability existing in multi-channel microwave module, a quick-plug automatic test system for multi-channel microwave module has been designed. Virtual instrument is adopted as the programming language of the automatic test system software, and functions such as automatic equipment control, instrument test control, data acquisition and analysis processing with multi-channel testing as the core are designed to meet the automatic test requirements of multi-channel microwave module. The verification results show that the test system issues control instructions to the automated equipment through the test software to collaborate with the test system to complete actions such as material retrieval, testing, and material discharge. It controls the combination relationship between the test instrument and the matrix switch according to the designed test process to achieve multi-channel switching testing. The test system can be flexibly applied to various types of microwave module test scene. Compared with the limitation of conventional test system that cannot efficiently complete multi-channel tests, it can significantly improve the test efficiency and quality of multi-channel microwave module.
