A Multi-channel Spectrum Auto-monitor for Satellite Communications Signal

A multi-channel spectrum on-line auto-monitor method for satellite communications signal is designed, which is different from the traditional single-channel method based on the spectrum analyzer. To realize the novel method, a suitable signal monitoring point is selected firstly, a system architecture of "monitoring point & directional coupler & integrated matrix network & spectrum test unit & monitoring terminal" is built secondly, and a comprehensive testing software is used for testing points selection and testing indicators control. As a result, real-time multi-channel spectrum signal analysis, threshold alarms and continuous sampling process saving is realized. Proven, real-time, and high data accuracy, improve work efficiency, the promotion and practical value.
