Calibration for NA, CAT, and VVM Modes
Why and When to Calibrate
Before performing an O,S,L Cal, set the Measurement type, Frequency Range,
Power Level, and Resolution of the measurement. The calibration will remain
highly accurate until these settings change, or the physical connection to the
FieldFox changes.
— Disconnect the DUT from the FieldFox.
— If a jumper cable or adapter is required to connect the DUT to the FieldFox,
then connect those components to the FieldFox Out connectors NOW. The
effects of those components will be measured and removed during the
calibration, and only the effects of the DUT will be displayed in the
measurement results. These should be high-quality components!
— In CAT or NA Mode, press Cal 5.
— Then (if necessary) press
— Then using the
and gender of your DUT port to be measured and press Enter. This will
determine the type and gender of Cal Kit to use. For example, if a Type-N
Male connector is used on the DUT port to be measured, then the Type-N
Male standards (OPEN, SHORT, AND LOAD) will ALL be connected in place
of the DUT during the calibration.
— If there is more than one Cal Kit for the selected connector type, press
Kit
Calibration kit definitions are unique to each connector type and connector
sex. They must be correctly applied to obtain the most accurate
calibration.
— Then press
— Press Open, Short, and
— Connect the corresponding standard at the point where the DUT will be
connected, then press Measure.
— Measure each of the three standards. Standards can be measured again at
any time if you feel a standard was not connected securely.
— Press

Normalize

Normalize is used to calibrate a 2-port Insertion Loss measurement (CAT
Mode) and a S21 Transmission measurement (NA Mode). One of these
measurements must be selected before performing a Normalize Cal.
A Normalization Cal is REQUIRED to make accurate 2-port Transmission or
Insertion Loss measurements.
