Controlling the Spectrogram Update
The spectrogram starts running when you enter the spectrogram mode. By default, the
spectrogram is running in a continuous sweep mode.
If you are in single sweep mode, the R&S Spectrum Rider does not add a line to the
spectrogram until you initiate the next single sweep.
You can stop the update of the spectrogram in continuous sweep mode.
1. Press [MEAS] key.
2. Select "Hold" softkey.
Note that in continuous sweep mode, the measurement in the spectrum result dis-
play does not stop. The trace in the upper window still updates continuously but the
spectrogram view stops.
3. Select "Hold" softkey again.
The R&S Spectrum Rider resumes updating the spectrogram.
The spectrogram result display is filled with results until you change a measurement
setting. When a setting is changed, the spectrogram clears the existing result and
starts to fill again.
You can also clear the spectrogram manually.
1. Press [MEAS] key.
2. Select "Clear" softkey.
Couple spectrogram level and range settings to spectrum
Changes in the spectrogram level and range can also be reflected in the spectrum
mode and vice versa.
1. Press [MEAS] key.
2. Select "Settings" softkey.
3. Select "Display" softkey.
4. Select "Couple to Spectrum" menu item to enable the checkbox.
The R&S Spectrum Rider menu item is marked by an [X].
