Save the Calibration

After performing any type of calibration, you can save the FieldFox settings
along with the calibration into a STATE (*.sta) file. These settings and
calibration can then be recalled as necessary. To learn how, see
Recalling Files" on page 804

CalReady Properties

There are several factory calibrations (CalReady) on every FieldFox. These can
be selected based on the type of DUT that you measure most often, and the
compromise that you prefer to make between measurement speed versus
measurement accuracy. Remember, CalReady was performed at the test ports.
Therefore, a CalReady calibration is most accurate when the DUT is directly
connected to the test ports. Learn more in
