Application Note: Signal Monitoring, Surveillance, And Real-Time Spectrum Analysis

RF signal monitoring and surveillance applications have special equipment requirements that often go well beyond the typical radio receiver or spectrum analyzer. The Real-Time Spectrum Analyzer (RTSA) has many superior capabilities for signal monitoring and surveillance. In this application note, we review the basic challenges of intercepting and analyzing signals. Starting with overt compliance monitoring and advancing to the intercept of low probability of detection covert signals, RTSA technology for triggering, capturing and analyzing SIGnal INTelligence (SIGINT) is explained.
