Real-time spectrum replayer
The Real-time Spectrum Replayer lets you retrieve and replay recorded real-time spectrum analyzer traces in interference analysis
mode. These traces can be played back in the persistent spectrum, persistent spectrogram or persistent RSSI. You can configure
the limit line to create failure points when signals exceed it. The failure points are clearly displayed on the trace timeline for quick
