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 Cable Rider ZPH 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 Cable Rider ZPH shows a "Pass" message in the measurement dia-
gram. When one single value (i.e. one pixel) is outside of the limits, the R&S Cable
Rider ZPH 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 Cable Rider ZPH beeps each
time a limit is violated.
