Figure 7-2: RF sine wave signal with low S/N ratio with an averaged trace
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.
The RF signal can be distinguished from noise more clearly.
Figure 7-3: RF sine wave signal with low S/N ratio with a smaller video bandwidth
7. By reducing the resolution bandwidth by a factor of 10, the noise is reduced by
10 dB. Set the RBW to 100
kHz.
