1. Press [MEAS] key.
2. Select "Meas Mode" softkey.
The R&S Spectrum Rider opens a submenu to select the measurement mode.
3. Select the "Spectrogram" menu item.
The R&S Spectrum Rider starts the spectrogram result display.
By default, the spectrogram result display consists of two windows. The upper window
shows the measured spectrum as a trace line. The lower window shows the measure-
ment results in a spectrogram. The chronological information in the spectrogram is
restricted by the internal memory of the R&S Spectrum Rider. The R&S Spectrum
Rider stores 1024 frames or spectrums that have been measured in its memory. As the
height of the display is smaller, some of the data becomes invisible after a time.
