RTSA (Real-Time Spectrum Analyzer) Mode—Option 350 (CPU2 Only)
Record/Playback (RTSA Option)
— Record Interval Sets the amount of time to wait between individual trace 
recordings. Default is MIN, which is to wait 0 seconds (record traces as fast 
as possible). Enter a value in seconds between 0 (no delay) and 10,000 
seconds - about 3 hrs) using the numeric keypad,   arrows, or the rotary 
knob. 
— Segment Count
 Sets the number of traces to record, after which the 
recording will automatically pause. Press Pause/Resume or Record to 
capture another N traces, or Stop to end recording. Default is OFF, which is 
NO limit to the number of traces to be recorded. 
When set, a counter appears in the lower-left corner which counts UP to 
the specified number of recordings. 
Record Source
RTSA can only record one of the four possible traces. The simplest way to use 
Record Playback is to use First Active Trace (default trace).
