Set Trigger Holdoff

Trigger Holdoff sets the time, after triggering on an event, that the instrument waits before detecting the same trigger event to

start the next acquisition.

Setting the correct holdoff time is important to get a stable trigger. The longer holdoff time for the top waveform causes unstable

triggering. The shorter holdoff set for the bottom waveform only triggers on the first pulse in the burst to remedy the unstable

trigger.

Prerequisite: You have set up a trigger event for a signal.

1. Double-tap the Trigger badge on the Settings bar to open the Trigger configuration menu.

2. Tap the Mode & Holdoff panel.

3. To set a specific holdoff time, tap Time, then tap Holdoff Time and use the assigned multipurpose knob to specify a holdoff

time. Or double-tap the field and use the virtual keypad to enter a holdoff time.

4. To delay the trigger a random amount of time between triggers, tap Random.

Trigger on sequential events (A and B triggers)

Use the A and B Trigger Events to trigger on a second event after a first event occurs.
