Calready; How To Perform A Calibration - Keysight N9923A User Manual

Calibration for NA, CAT, and VVM Modes
— A THRU standard is used during some calibration steps to connect PORT 1
Calibration Reference Plane is the point (or points) at which the DUT and cal
standards are connected during a calibration. This can be at the FieldFox test
port connectors, or at the end of jumper cables or adapters.

CalReady

Every FieldFox contains a factory calibration that was performed at the port 1
and port 2 connectors, with -15 dBm input power, over the entire frequency
range of the FieldFox using a number of data points that allows reasonable
interpolation over the FieldFox frequency range.
This calibration, known as CalReady, allows you to immediately make
measurements of a DUT that is connected directly at the test ports (PORT 1
and/or PORT 2). CalReady corrects measurements when the FieldFox is turned
ON and when a measurement is created with no other correction in place.
When measuring a DUT using a jumper cable or adapter - NOT a direct
connection to a test port connector – then a QuickCal or Mechanical Cal is
recommended. CalReady can also be used to check the integrity of the jumper
cable that is attached to the test ports.
