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 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 have their sensor calibration tables stored in EEPROM

which means that the reference calibration factor is automatically downloaded by

the power meter.
