Calibration Subsystem - HP E4418B Programming Manual

CALibration Subsystem

CALibration Subsystem
CALibration Subsystem
The CALibration command subsystem is used to zero and calibrate the
power meter. It is also used to set the reference calibration factor for the
power sensor which is being used.
The numeric suffix of the CALibration program mnemonic in the
CALibration commands refers to a channel, that is CALibration1 and
CALibration2 represent channel A and channel B respectively. If you are
using the single channel HP E4418B power meter the CALibration2
commands are irrelevant and cause the error "Header suffix out of range."
Zeroing and calibration of the power meter is recommended:
The CALibration commands, with the exception of RCFactor, are all
overlapped commands, that is, the power meter can continue parsing and
executing subsequent commands while initiated. Refer to "Using the
Operation Complete Commands", on page 1-89 to determine when the
commands are complete.
