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 time since last calibration is greater then 1000 minutes.

The 0|OFF parameter is only required for the query response and is ignored in the

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 zeroed before calibration using the CALibration:ZERO:AUTO ONCE
