Setting channel bandwidth
The channel bandwidth defines the frequency range around the center frequency, over
which the R&S Spectrum Rider performs the power measurement.
1. Press [MEAS] key.
2. Select "EIRP Settings" softkey.
The R&S Spectrum Rider opens a submenu to select the input parameters for
EIRP settings.
3. Select the "Channel BW" menu item.
The R&S Spectrum Rider opens an input field to specify the channel bandwidth.
4. Enter the channel bandwidth you required.
The R&S Spectrum Rider sets the appropriate span for the channel bandwidth that
you have entered (span = 1.2 x channel bandwidth). This ensures that no incorrect
channel power measurements are made.
The minimum channel bandwidth that you can set is 833 Hz at a span of 1 kHz.
Setting input parameters for EIRP
The input parameters such as antennna gain (dB) , cable loss (dB) and distance
(meter or feet) are taken into consideration during the calculation of EIRP measure-
ment. See
on page 168 and
1. Press [MEAS] key.
2. Select "EIRP Settings" softkey.
The R&S Spectrum Rider opens a submenu to select the input parameters for
EIRP settings.
● "Antenna Gain": Input parameter in dB, value is displayed in dBi in the EIRP
info bar
● "Cable Loss": Input parameter in dB, value is displayed in dB in EIRP info bar
● "Distance": Input parameter in meter or feet, value is displayed in meter or feet
in EIRP info bar
3. Select the required settings.
4. Enter the value according to the selected settings.
Max hold for EIRP
The "EIRP Max Hold" displays the maximum hold value in the EIRP info bar. To reset
the max hold value, do the following:
1. Press [MEAS] key.
2. Select "Reset Max Hold" softkey.
The R&S Spectrum Rider reset the "EIRP Max Hold" value.
