Averaging; Single/Continuous - Agilent Technologies FieldFox N9923A User Manual

Averaging

Averaging helps to reduce the effects of random noise on a measurement. The
FieldFox computes the displayed value over several consecutive readings.
Average count determines the number of readings to average. The higher the
average count, the greater the amount of noise reduction.
An average counter is shown in the left edge of the screen as Avg N. This shows
the number of previous readings that have been averaged together. When the
counter reaches the specified count, then a „running average‟ of the last N
readings is displayed.
Average count = 1 means there is NO averaging.
This setting can be changed at any time without affecting calibration accuracy.
How to set Averaging
 Press Meas Setup 4
 Then
 Then

This setting can be changed at any time without affecting calibration accuracy.
How to set Single or Continuous
 Press Sweep 3.
 Then choose one of the following:
 You can also use Run / Hold +/- to toggle between Single and Continuous.
