2.8.6 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.
