Abstract
According to high resolution SAR/GMTI satellite subsystem antenna subsystem SAR antenna secondary power supply (hereinafter referred to as secondary power supply) multi-channel output, low output voltage, large current pulse load and a series of characteristics, this automatic test system through VEE software to the secondary power program in-depth development and improvement, and through the GPIB line control hardware equipment instrument, the realization of secondary power multi-channel simultaneous monitoring output waveform, multi-frequency special, command automatic switch machine, etc. test efficiency and reliability. Through the analysis and optimization of the test items of the secondary power supply, the automatic test system has designed a general programmable program, and can be applied to a variety of secondary power modules and single machine, the compatibility is very strong. At present, this automatic test system has been applied to the test of multiple types of SAR antenna secondary power supply, the test quality is 100% correct, the efficiency is greatly improved, and the results are remarkable.
