Performing Limit Checks
Limit violation
Note that a limit check fails only if the signal exceeds the limit line. If the signal level is
the same as the limit value, the limit check passes.
If limit lines are active, the R&S
ZNH automatically checks the trace for limit violations
after each frequency sweep. As long as the signal does not violate the limit line, the
R&S
ZNH shows a "Pass" message in the measurement diagram. When one single
value (i.e. one pixel) is outside of the limits, the R&S
ZNH displays a "Fail" message in
the diagram area and, in addition, sounds a beep.
A limit check relates only to the frequency range defined by the limit line, not the span.
Audio signal
You can turn the acoustic signal that sounds in case of a limit violation on and off.
► Select the "Audio Beep" menu item.
Once selected, the audio beep is active, the R&S
ZNH beeps each time a limit is
violated.
