Zone Qualified Trigger
The zone qualified trigger feature gives you one or two rectangular areas, Zone 1
and Zone 2, that a waveform must either intersect or not intersect in order for an
acquisition to be displayed and stored in memory.
The zone qualified trigger feature works on top of the oscilloscope's hardware
trigger, which determines the acquisitions whose waveforms are evaluated for
zone intersection.
To set up a zone qualified trigger:
1 Touch the upper-right corner to select the rectangle draw mode.
2 Drag your finger (or connected USB mouse pointer) across the screen to draw a
rectangular zone that the waveform must either intersect or not intersect.
3 Take your finger off the screen (or release the mouse button).
4 In the popup menu, select whether the rectangle is Zone 1 or Zone 2 and
whether it is a "Must Intersect" or "Must Not Intersect" zone.
