4 CALibration Subsystem

CALibration[1]|2:AUTO [ONCE|ON|OFF|0|1]

This command calibrates the specified channel when enabled. The
command assumes that an 8480, E- Series or N8480 Series power sensor is
connected to a 1 mW reference signal.
1|ON can only be used with a P- series sensor. When 1|ON is enabled the
calibration is updated if the meter's or sensor's temperature changes by
±
The 0|OFF parameter is only required for the query response and is
ignored in the command.
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.
For 8480 Series power sensors and N8480 Series power sensors with
Option CFT, the reference calibration factor used during this calibration
can be obtained from an active sensor calibration table or the value
entered using CALibration:RCFactor. The actual value used is the one
which was most recently set. For example, a value entered using
CALibration:RCFactor is overridden if a sensor calibration table is
subsequently selected and enabled and CALibration:RCFactor overrides
any reference calibration factor previously set from a sensor calibration
table. To determine the current reference calibration factor, use
CALibration:RCFactor?.
If the power meter is using an 8480, E-Series or N8480 Series power sensor it should be
N O T E
zeroed before calibration using the CALibration:ZERO:AUTO ONCE command.
