Smoothing; Single/Continuous; Resolution (Number Of Points) - Keysight N9923A FieldFox User Manual

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
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 26.

Single or Continuous Measure
This setting determines whether the FieldFox measures continuously or only once
each time the

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.
Resolution (Number of Data Points)
Data points are individual measurements that are made and plotted across the X-
axis to form a trace. Select more data points to increase measurement resolution.
However, more data points requires more time to complete an entire measurement
sweep.
When the Resolution is changed after a calibration is performed, the cal becomes
interpolated. Learn more on page 62.
