Setting the Resolution Bandwidth
Use
The span and the resolution bandwidth can be set independently. In the de-
fault setting, however, these two parameters are coupled to make operating
the instrument easier. This setting is recommended for many applications
because operating errors are prevented. To make certain measurements, it
may be necessary to set the resolution bandwidth and the span independ-
ently. With the R&S FS300, you can manually set resolution bandwidths from
200 Hz to 1 MHz in a 1, 2, 3, 5, 10 sequence.
