IF Bandwidth
The FieldFox converts the received signal from its source to a lower intermediate
frequency (IF). The bandwidth of the IF bandpass filter is adjustable. Reducing
the IF receiver bandwidth reduces the effect of random noise on a measurement.
However, narrower IF bandwidths cause longer sweep times.
How to set IF BW
 Press BW 2.
 Then
 Then choose from the following:

Smoothing

Trace smoothing averages a number of adjacent data points to smooth the peak-
to-peak noise values on a displayed trace. The number of adjacent data points
that are averaged is known as the smoothing
specifying a percentage of the X-axis span.
Trace smoothing does NOT significantly increase measurement time.
Smoothing is used in Group Delay measurements, although it can be used with
any NA format EXCEPT Polar or Smith Chart. Learn more about NA Mode
formats, including Group Delay, on page 23.

Single or Continuous Measure
This setting determines whether the FieldFox measures continuously or only
once each time the
power or to allow you to save or analyze a specific measurement.
This setting can be changed at any time without affecting calibration accuracy.
How to set Single or Continuous
 Press Sweep 3.
