–
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).

erated if the limit check is switched off.

In contrast to 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.
