Performing Limit Checks
If limit lines are active, the R&S Spectrum Rider 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 Spectrum Rider shows a "Pass" message in the measurement diagram.
As soon as one single value (i.e. one pixel) is outside of the limits, the R&S Spectrum
Rider 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 Spectrum Rider beeps each time
a limit is violated.
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.

Working with Channel Tables
Almost all transmission systems divide their assigned frequency ranges into channels.
Each channel corresponds to a specific frequency. To keep the handling of such sys-
tems simple, you can use channel tables instead of entering frequencies manually.
The R&S Spectrum Rider already comes with an assortment of channel tables that you
can use without doing anything. If you want to test transmission standards that are not
listed, you can also build channel tables manually with the "Channel Table Editor" of
the R&S InstrumentView software package that is delivered with the R&S Spectrum
Rider. To use one of the edited channels, you have to copy the channel table to the
R&S Spectrum Rider.
For more information on channel table, see
Chapter 4.8, "Managing Datasets"
