The following examples show how to perform various calibrations in CAT and NA modes.

About Calibration Settings A calibration session that is performed using the front-panel is completely separate from a calibration session that is performed programmatically. Therefore, calibration settings that are made remotely (such as setting the cal kit and connectors) can NOT be observed from the front-panel user interface. Alternatively, calibration settings are that are made from the FieldFox front panel (user interface) can NOT be queried programmatically. |
Guided Calibration (separate topic)
ECal (separate topic)
Note: To Cal a VVM mode measurement, perform a Cal in CAT or NA mode, then switch to VVM mode.

To perform a 1-port cal on port 2, replace all the ‘1’ arguments with ‘2’.
