Calibration Procedures 3
Keysight E3631A Service Guide 51
You can also enter calibration constants from the remote interface. Remote
operation is similar to the local front-panel procedure. You can use a computer to
perform the adjustment by first selecting the required setup. The calibration value
is sent to the power supply and then the calibration is initiated over the remote
interface. The power supply must be unsecured prior to initiating the calibration
procedure. A Keysight BASIC program for calibration over the GPIB interface is
listed at the end of this chapter.
For further details on programming the power supply, see chapters 3 and 4 in the
Keysight E3631A User's Guide.
