5.3 GPIB
5.3.1 Overview
GPIB (General Purpose Interface Bus) allows external control of the 6146/6156 source value settings,
parameter settings, and reading data, making it simple to configure an automated measurement system.
As GPIB signals from the 6146/6156 are electrically isolated inside the unit from the source signal system,
the connection of external devices does not affect the source values.
The remote commands are the same as with USB.
