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 Meas Setup
 Then choose one of the following:
 You can also use Run / Hold +/- to toggle between Single and Continuous.

VVM Calibration

CalReady is accurate for most zeroed VVM measurements at frequencies below
about 6 GHz. For the very highest accuracy, especially above 6 GHz, then perform
a QuickCal or Mechanical Cal. Learn more on page 64.

Zeroing

Zeroing, also known as Normalization, or Data/Memory, simply "Zeroes" the
Magnitude and Phase display when
measurements are relative to the measurement that was made when Zero was
pressed.
When an instrument state is saved with Zero ON, the zeroing data is saved with
the state file, similar to how a calibration is saved with a state file.
