The electromagnetic spectrum (EM) is filled with complex continuous wave (CW) and modulated RF/Microwave signals, with many of these signals carrying important information such as digital information or location signals (radar). The ability to sense and analyze these signals aids in identifying interference causes and deducing component, device, and system behavior. Real-time spectrum analyzers enable on-the-go sensing and analysis of these signals and can put powerful software analysis tools at an engineer's fingertips.
