5. To suppress noise spikes, average the trace. In the "Traces" configuration dialog,
set the "Trace Mode" to "Average" (see
The traces of consecutive sweeps are averaged. To perform averaging, the
R&S
FPL1000 automatically switches on the sample detector. The RF signal,
therefore, can be more clearly distinguished from noise.

6. Instead of trace averaging, you can select a video filter that is narrower than the
resolution bandwidth. Set the trace mode back to "Clear/ Write" , then set the VBW
to
10
kHz
manually in the "Bandwidth" configuration dialog.
