–
If "Limit Check" is enabled, the limits are checked, no matter if the limit lines
are displayed.
–
The limit check can even be enabled, if no limit lines are defined. In this case,
the info field displays "No limit defined!" and the limit check always passes.
●
Limit lines are defined for a particular trace format. However, the limit check is per-
formed irrespective of the current trace format. The info field indicates the correct
"PASS"/"FAIL" state and limit violations are visualized on the trace (if any).

Limit Fail Beep
Activates or deactivates the fail beep. The fail beep is a low-tone acoustic signal that is
generated each time the analyzer detects an exceeded limit. No fail beep can be gen-
erated if the limit check is switched off.
Note:
In contrast to the R&S
ZNB, the R&S
ZNBT does not have a built-in audio
device and loudspeaker. To hear these sounds, connect a USB audio device to the
R&S
ZNBT or operate it via remote desktop.

Check" is selected.
