Press the Average softkey.
T
he traces of consecutive sweeps are averaged. To perform averaging, the R&S FSL
automatically switches on the sample detector. The RF signal, therefore, can be more clearly
distinguished from noise.

5. Instead of trace averaging, a video filter that is narrower than the resolution bandwidth can be
selected.
Press the Trace Mode key.
Press the Clear Write softkey.
Press the BW key.
Press the Video BW Manual softkey and enter 10 kHz.
The RF signal can be more clearly distinguished from noise.
