Abstract:

A spacecraft multi-RF electrical spectrum automatic monitoring and measuring system has been designed in order to improve the efficiency of spacecraft RF signals monitoring and measuring. RF spectrum is measured by the spectrum analyzer, and the different RF signal channels are switched by the microwave switch matrix equipment. A multi-RF spectrum automatic monitoring and measuring software has been developed to control the whole system and perform read-write operation of data. Automatic monitoring and measuring of 15 RF signal spectrums with frequency range between 50 MHz and 3 GHz is implemented. The efficiency of spacecraft RF signal monitoring is improved significantly, with the time cost reducing from 3min/channel to 10 s/channel and manpower saving from 2 to 1. This system has been applied in testing of Chinese space station.
