CALibration[1]|2[:ALL]?

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

command, it provides a response to indicate whether the calibration has been

successful or not.

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

specified channel. The query 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).

When the calibration sequence is completed, 0 or 1 is entered into the output

buffer to indicate if the sequence was successful. If the result is:

– 0, the calibration has passed

– 1, the calibration has failed

For the 8480 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?.

The 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.
