Averaging (CAT, NA, Power Meter, Channel Scanner, and Pulse
Measurement Modes Only)
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
—Press BW 2.
Then Average N
where N is the current count setting.
Enter a value using the numeric keypad. Enter 1 for NO averaging.
—Press Enter
.
While Trace Averaging is in process, press Sweep 3
then Restart to restart the averaging at 1.
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
“Increase Dynamic
Range” on page 108
