Calibration[1|2]:Auto <Boolean>|Once - HP E4418B Programming Manual

CALibration[1|2]:AUTO <Boolean>|ONCE
This command is used to calibrate the specified channel when ONCE is
selected. The command assumes that the power sensor is connected to a
1 mW reference signal. The 0|OFF parameter is only required for the
query response and is ignored in the command. If 1|ON is selected, it
causes the error -224, "Illegal parameter value" to occur.
For the HP 8480 series power sensors 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 HP E-series power sensors have their sensor calibration tables stored
in EEPROM which means that the reference calibration factor is
automatically downloaded by the power meter.

The power meter should be zeroed before calibration using the
CALibration:ZERO:AUTO ONCE command.
