video bandwidth (VBW) and the resolution bandwidth (RBW) must be ≥

 

10/1 to maintain the accuracy of the measurement.

11.Return the resolution bandwidth to 1 kHz. Press BW/Avg, 1, kHz.

12.Measure the noise very close to the signal by pressing Marker, 50.0000, MHz (or use the front-panel knob to place the marker). See Figure 1-46.

Note that the marker reads a value that is too high because some of the averaged trace points are on the skirt of the signal response.
