Today’s Real-Time Spectrum Analyzers include features and capabilities that go far beyond the basic measurement capabilities of conventional spectrum analyzers. Among these capabilities is the ability to capture and record RF data vs. time for playback and analysis. So, what is RF Capture and Playback? It turns out, the answer is multi-faceted. There are several different ways that today’s real-time analyzers can capture and record RF signals. The captured data can be played back in a number of different ways. Let’s examine the various aspects of RF Capture and Playback.
