Meas Off (Spectrum Analyzer) Measurement
Mode
Trig Slope Controls the trigger polarity. It is set positive to trigger on a rising edge and
negative to trigger on a falling edge.
Trig Delay Controls a time delay during which the analyzer will wait to begin a sweep
after meeting the trigger criteria. You can use negative delay to pre-trigger the instrument
in time domain, but not in swept spans.
Dependencies / Couplings The range of the Video Trigger Level is dependent on the Reference
Level.
Trigger level selection is not available with free run or external
triggering.
