Qualified Trigger
Qualified arms the trigger on the A event, then fires on the B event. In Normal trigger mode, it automatically
resets after the B event. The options for the B event depend on the type of A event. You may apply additional
Holdoff by time or number of events.
On the Trigger dialog, select Qualified trigger type to display the controls.
Besides an Edge level, the arming ("A") event may be a State, any voltage measured above or below a
threshold Level.
Once you've selected the A and B events on the Qualified dialog, set up the conditions on the respective sub-
dialogs exactly as you would a single-stage trigger.
