Smoothing; Resolution (Number Of Points) - Agilent Technologies FieldFox N9912A User Manual

 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 40.

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.
 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 also takes 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 54.
