CALibration[1|2][:ALL]
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.
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:
• Zeroing the power meter (CALibration:ZERO:AUTO ONCE), and
• calibrating the power meter (CALibration:AUTO ONCE).
For the Agilent 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 Agilent 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.
