Trigger Holdoff
You can use the Trigger Holdoff function to produce a stable display of complex
waveforms. Holdoff is time between when the oscilloscope detects one trigger and
when it is ready to detect another. The oscilloscope will not trigger during the holdoff
time. For a pulse train, you can adjust the holdoff time so the oscilloscope triggers
only on the first pulse in the train.
