Holdoff. You can use the Trigger Holdoff function to produce a stable
display of complex waveforms, such as pulse trains. Holdoff is the
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.
