NOTE:
Press the SINGLE button when you want the oscilloscope to
acquire a single waveform.
Trigger coupling affects only the signal passed to the trigger system.
It does not affect the bandwidth or coupling of the signal displayed
on the screen.
Normal Polarity Sync triggers always occur on negative-going
horizontal sync pulses. If the video waveform has positive-going
horizontal sync pulses, use the Inverted Polarity selection.
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.
