When do I use the Sample detector?

The sample detector can be used to measure both CW signals and noise, thus it is useful for making Signal-to-Noise ratio measurements.  However, it is harder to use than peak detector for CW signals, and slower to average for noise.  To measure a CW signal, either the RBW must be significantly wider than a display point or you must carefully tune the analyzer to get the peak of the CW signal.  To measure noise, you must use some form of averaging.
