Calibration for NA, CAT, and VVM Modes
Why and When to Calibrate

Preset Calibration (also known as CalReady)

CalReady (Preset calibration) only applies to S11 and Return Loss
measurements. CalReady does not apply to S21 or Insertion Loss
measurements. Also, you can interpolate the S11 calibration, but you
cannot interpolate the S21 calibration or S21 normalization.
Every FieldFox is factory calibrated at the RF Out connector over the entire
frequency range of the FieldFox using a number of data points that allows
reasonable interpolation over the FieldFox frequency range.
This CalReady condition allows you to start using your FieldFox immediately if
you are measuring a device that is directly connected to the RF Out test port.
CalReady applies to the entire frequency range of the FieldFox. It can be used
to check the integrity of the jumper cable.
Cal ON
When measuring a DUT using a jumper cable or adapter - NOT a direct
connection to the RF Out connector – then a QuickCal or O,S,L Cal is
recommended.
Learn how to see when your factory CalReady calibration was performed in
"System Information" on page 22

QuickCal

QuickCal is ideal for a quick and simple calibration of the measurement when
using a jumper cable or adapter to connect the DUT to the FieldFox test ports.
QuickCal corrects for phase shift, time delay, and loss of adapters or jumper
cables.
QuickCal does not require a specific Cal Kit and is a very simple calibration. If
the highest accuracy is required, a mechanical calibration with a high quality
calibration kit is recommended.
If the DUT has 3.5 mm-female or SMA-female connectors, QuickCal is NOT
recommended.
How to perform a QuickCal
Press Esc at any time durign the QuickCal to stop the calibration.
— In CAT, NA, or VVM Mode, press Cal 5.
— Then (if necessary) press
— Press
No Connection
— Disconnect the DUT from the FieldFox.
