4.1.3 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 a occupied bandwidth of 99 %. Therefore this is the
default setting. 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 ZVH automatically selects the
measurement parameters so that you can attain the best result.
► Press the MEAS key.
► Press the "Meas Mode" softkey.
The R&S ZVH opens the measurement menu.
► Select the "Occupied BW" menu item.
The R&S ZVH starts to measure the occupied bandwidth.
Two vertical lines show the occupied bandwidth.
