As the computing time for the FFTs was small compared …

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 WebBy continuing to increase the RBW until the RBW is greater than the reciprocal of the pulse width (wider than the null spacing), the whole spectrum of the pulsed signal falls within …
