The range is from 0 to 10, where "0" corresponds to the left side of the bargraph
and "10" corresponds to the right side of the bargraph.
You can also select the level range that the bargraph covers. In the default state, the
bargraph covers 100 values of the unit you have selected (e.g. 100 dB
µ
V).

Performing Frequency Scans
Compared to single frequency measurements, frequency scans perform a measure-
ment on a particular set of receive frequencies. The scan measures only those fre-
quencies that are defined in the frequency range. The space between the receive fre-
quencies is not considered in the measurement.
The R&S Spectrum Rider shows the results for a frequency scan in a graphical result
display. The horizontal axis in that display represents the frequency spectrum covered
by the scan. The vertical axis represents the power levels.
The power levels for each frequency contained in the scan are represented by a verti-
cal line at the receive frequencies that have been measured. This type of display
emphasizes the fact that the scan measures single receive frequencies only and not
the frequencies between those receive frequencies.
1. Press [MEAS] key.
2. Select "Freq Scan" softkey.
The R&S Spectrum Rider shows the scan result display. See
