Averaging
Trace Averaging helps to smooth a trace to reduce the effects of random noise
on a measurement. The FieldFox computes each data point based on the
average of the same data point over several consecutive sweeps.
Average Count determines the number of sweeps 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 sweeps that have been averaged together to
form the current trace. When the counter reaches the specified count, then a
‘running average’ of the last
N
sweeps 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 Trace Averaging

Scale annotation on the FieldFox screen
Reference Line = red arrow
Ref Level = -40 dB
Ref Position = 1
Scale = 2 dB per division
Averaging is often used to increase the dynamic range of a measurement.
To achieve the highest dynamic range, select NA mode and reduce the IF
Bandwidth setting. Learn more about dynamic range in
