2. Select "Freq Mode" softkey.
The R&S Spectrum Rider opens a submenu that contains the channel menu items.
3. Select the "Set to Downlink " or "Set to Uplink" menu item.
The R&S Spectrum Rider maps the channel number to the appropriate uplink or
downlink channel table.
Selecting a channel
Entering a center, start or stop frequency is not possible anymore. Instead you select a
channel. The R&S Spectrum Rider then adjusts the center, start and stop frequency
according to the channel table.
1. Press [FREQ] key.
2. Select "Center Frequency" softkey.
The R&S Spectrum Rider opens an input field to select the channel.
3. Enter the channel you want to perform measurements on.
The R&S Spectrum Rider changes the channel according to the channel table.
Channel numbers are assigned to frequencies as follows:
● The first channel is assigned a channel number and a frequency.
● All subsequent channels have ascending numbers.
● The frequency spacing between channels is fixed. It can also be negative, i.e.
the center frequency of the R&S Spectrum Rider decreases with ascending
channel number.
● In transmission systems containing gaps in the frequency range (as in the case
of television, for example), a channel table can comprise multiple ranges.

Using Transducer Factors
The frequency-dependent transducer factor of transducers and antennas can be
directly considered in the measurement result. A transducer factor consists of a
numeric value and a unit. The R&S Spectrum Rider corrects the level values of the
trace by the values of the transducer. At the same time, the unit of the transducer is
assigned to the level axis. When field-strength measurements are performed with the
aid of antennas, for instance, the electrical field strength is directly indicated in dB
µ
V/m
on the R&S Spectrum Rider. A transducer factor can also be used to correct a fre-
quency-dependent attenuation, e.g. of a cable between DUT and RF input of the R&S
Spectrum Rider.
