In satellite TT&C station,manually monitoring spectrum of downlink IF signal is a low effective way and it has no automatically spectrum dealing way. To solve the problems,the paper designs and implements a multi-spectrums monitoring system based on a switch matrix and two spectrum analyzers. First,the paper introduces the hardware structure of the system. Then,the paper introduces the design framework of system software. Next,to implement the functions of the system,the paper designs some dealing algorithms about spectrum monitoring. The algorithms are monitoring spectrum in real time based on SCPI,detecting abnormal signal based on critical line,recording and replaying spectrum based on trace data,and a fast automatically capturing telecommand. At last,it is illustrated that the system satisfies the requirements of spectrum monitoring by experiments. According the actual application,the system can run stably and reliably,and the algorithms are practical and effective.
