Measuring the Occupied Bandwidth
The proper operation of a transmission network requires that all transmitters adhere to
the bandwidths assigned to them. The occupied bandwidth is defined as the bandwidth
that contains a specified percentage of the entire power of the transmitter.
Numerous standards require an occupied bandwidth of 99 which is also the default set-
ting. If you need another percentage for the occupied bandwidth, you can set values
from 10 % to 99.9 %.
After entering the channel bandwidth, the R&S Spectrum Rider automatically selects
the measurement parameters so that you can attain the best result.
1. Press [MEAS] key.
2. Select "Meas Mode" softkey.
3. The R&S Spectrum Rider opens a submenu to select the measurement mode.
4. Select the "Occupied BW" menu item.
The R&S Spectrum Rider starts to measure the occupied bandwidth.
Two vertical lines show the occupied bandwidth.
