Example:
If you have configured the A-trigger at last, and the trigger level for C1 is 70 mV, ena-
bling the coupling sets the trigger levels for C1 in the B- and R trigger also to 70
mV. If
the B-trigger and/or R-trigger use another source as the A-trigger, the level remains
unchanged.

Zone trigger
The zone trigger triggers on the intersection or non-intersection of the signal and one
or more zones or masks. The zone can be applied to any active input signal, math
waveform including FFT, and XY-waveform.
You can use the zone trigger, for example, to solve the following tasks:
●
Trigger if a peak in the spectrum occurs: define a zone in the FFT diagram to filter
amplitude peaks. In the same way, you can filter harmonics.
●
Separate rising and falling edges: define a zone around the base or top of the data
signal.
●
Separate read/write cycles: define a zone in the eye diagram.
●
Identify a tube violation of signals with an infrequent non-monotonic edge.
●
Filter events in the history, after acquisition has finished
To document the trigger events, use the actions on trigger. For example, create a
report when the instrument triggers, or save the waveform.
Zone trigger is not available for serial protocol triggers.
Trigger sequence with zone trigger
You can combine the zone trigger with common trigger conditions and use one of the
following trigger sequences:
●
"A
→
Zone"
●
"A
→
B
→
R
→
Zone"
●
"(A OR B)
→
ZoneTrigger"
In a sequence, the zone trigger acts like a filter on previous acquisitions. Previous con-
ditions and then the zone condition must be fulfilled. For example, in an "A
→
Zone"
sequence, the trigger marker is set to the A event, and a corresponding trigger-out sig-
nal is sent when the zone condition is fulfilled.

About trigger zones
A zone is a mask without result box. You can adjust the shape of the zone in the same
way as mask segments, graphically by dragging the corner points, or numerically in the
