Effect of resolution bandwidth and video bandwidth on the ...

WebUsing a wide RBW for the carrier-power measurement means that the signal will not have noise-like statistics. It will not have CW-like statistics, either, so it is still wise to set the VBW as wide as possible. But let’s consider some examples to see if the sample-mode bandwidths of spectrum analyzers are a problem. Zero span WebVBW and VBW Averaging.
