4 CALibration Subsystem
202 N1911A/1912A P-Series Power Meters Programming Guide
CALibration[1]|2[:ALL]
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.
NOTE
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.
