CALibration Subsystem

CALibration[1]|2[:ALL]

This command is identical to CALibration[1]|2[:ALL]?, however, unlike the

query it does not provide a response to indicate whether the calibration has

been successful or not.

This command causes the power meter to perform a calibration sequence on the

specified channel. The command assumes that the power sensor is connected to

the POWER REF output. The calibration sequence consists of:

1 Zeroing the power meter (CALibration:ZERO:AUTO ONCE), and

2 Calibrating the power meter (CALibration:AUTO ONCE).

For 8480 Series power sensors and N8480 Series power sensors with Option CFT,

the reference calibration factor used during this calibration can be derived from

either an active sensor calibration table or the value entered using

CALibration:RCFactor. The actual value used is the one which was most recently

set. That is, a value entered using CALibration:RCFactor is overridden if a sensor

calibration table is subsequently selected and enabled. Conversely,

CALibration:RCFactor overrides any reference calibration factor previously set

from a sensor calibration table. To determine the currently set reference

calibration factor use CALibration:RCFactor?.

E-Series power sensors and N8480 Series power sensors (excluding Option CFT)

have their sensor calibration tables stored in EEPROM which means that the

reference calibration factor is automatically downloaded by the power meter.
