4 CALibration Subsystem
226 Keysight N8262A 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 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 have their sensor calibration tables stored in EEPROM
which means that the reference calibration factor is automatically downloaded by
the power meter.
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.
