Calibration - Keysight Technologies FieldFox N9923A Quick Reference Manual

Calibration

Calibration is performed in NA, CAT, and VVM Modes.
A CalReady calibration is automatically applied to
measurements when the FieldFox is powered ON and
when Preset. This calibration sets the reference plane at
the test port connectors.
Calibration should be performed when any of the
following occur:
 The temperature changes significantly.
 The Frequency Range, Resolution, Min Swp Time, or
Power Level is changed.
 When using a phase stable jumper cable or adapter
to connect the DUT to the FieldFox. These should be
high-quality components.
After making measurement settings:
 Press Cal 5 then follow the prompts.
 For highest accuracy with minimum connections for
your setup, perform the Calibration Type that is
recommended by the FieldFox.
 During a QuickCal, press
using a jumper cable or adapter.
