Making Basic Measurements Using Spectrum Analyzer Mode

Measuring low-level Signals Using Attenuation, Video Bandwidth, and Video Averaging

3.To set the number of samples, use the number/units keypad. For example, press VID AVG OM OFF (so that ON is underlined), 25 (Hz). Turn

video averaging off and on again by pressing VID AVG ON OFF (OFF),

VID AVG OM OFF (ON).

The number of samples equals the number of sweeps in the averaging routine.

During averaging, the current sample appears at the left side of the graticule. Changes in active functions settings, such as the center frequency or reference level, will restart the sampling. The sampling will also restart if video averaging is turned off and then on again.

Once the set number of sweeps has been completed, the spectrum analyzer continues to provide a running average based on this set number.
