Holdoff Function
Holdoff sets the amount of time that the oscilloscope will wait
before re-initializing the trigger circuit. You can use the
holdoff function to stabilize the display of complex waveforms.
With the holdoff function, you can synchronize triggers. The
oscilloscope will trigger on one edge of the waveform, and
ignore further edges until the holdoff time is up. The
oscilloscope will then re-initialize the trigger circuit to wait for
the next edge trigger. This allows the oscilloscope to trigger
on a repeating pattern in a waveform.
Turn the Entry knob
to increase or decrease the trigger
hold off time shown in the Holdoff softkey. To get a stable
trigger on the pulse burst shown on the screen, set the
holdoff time to be slightly less than the period of the pulse
burst.
