4 CALibration Subsystem

CALibration[1]|2[:ALL]?

This query is identical to CALibration[1]|2[:ALL], however, unlike the
NOTE
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:
– Zeroing the power meter (CALibration:ZERO:AUTO ONCE), and
– 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 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?
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.
