CALibration Subsystem 4
U8480 Series Programming Guide 117
CALibration[1][:ALL]
This command causes the U8480 Series to perform a calibration sequence. For 
internal calibration (CALibration:TYPE INTernal), the calibration sequence 
consists of:
1 Zeroing the U8480 Series (CALibration:ZERO:AUTO ONCE) and
2 Calibrating the U8480 Series (CALibration:AUTO ONCE).
This command is not applicable for external calibration as the U8480 Series does 
not have control of the power reference.

This command is identical to CALibration[1][:ALL]?; however, unlike the 
query, it does not provide a response to indicate whether the calibration has 
been successful or not.
CAL This command causes the U8480 Series to perform a calibration
