Disabling both zones disables the zone qualified trigger feature. When
the zone qualified trigger feature is enabled, at least one zone must be
enabled.
You can press the [Zone] key to disable or re- enable the zone qualified
trigger.
When two non- overlapping zones are used, their conditions are ANDed to
become the final qualifying condition.
When two overlapping zones have the same condition, the zones are ORed.
When two overlapping zones have different conditions, Zone 1 takes
precedence and Zone 2 is not used. In this case, Zone 2 will have no fill
(that is, neither solid nor shaded) to indicate that it is not being used.
The zone qualified trigger feature is incompatible with, and will disable,
the XY and Roll horizontal time modes, the Averaging acquisition mode,
and the Segmented Memory acquisition feature.

Keep in mind that the TRIG OUT signal comes from the oscilloscope's hardware trigger. The
TRIG OUT signal indicates when there is a trigger (acquisition) that is evaluated for zone
intersection, not when an acquisition meets the zone qualification and is plotted on the
oscilloscope's display.
