Holdoff:
To use Trigger Holdoff, push the HORIZONTAL Menu button and set the Holdoff Time
option by pressing F4. The Trigger Holdoff function can be used to generate 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. During the holdoff time, the
oscilloscope will not trigger. For a pulse train, the holdoff time can be adjusted to let the
oscilloscope trigger only on the first pulse in the train.
