The testing of aerospace microwave components has always been an important subject in the field of testing. The parameters of microwave components are related to the overall performance of the radar system. Microwave components have become more complex in terms of structure, model, and test method, and have stricter requirements than before in terms of test efficiency and test accuracy. The microwave component automatic test system is an innovation for multi-channel microwave component testing. The design of the microwave test adapter chassis is compatible with the testing of multiple types of microwave test components. The FPGA-based control signal board is designed to complete the control of the test components signal output and real-time monitoring of the power supply system of the test system. In the microwave component automatic test system, the central computer is the main controller, which unifies all parts of the test system. The design of the automatic test software and the addition of data compensation meet the high requirements of test rate and test accuracy.
