5.3 GPIB
5.3.1 Overview
GPIB (General Purpose Interface Bus) allows you to externally set the measurement functions and
parameters on the 6253 and read out the measured data, making it simple to configure an automated
measurement system.
As GPIB signals from the 6253 are electrically isolated inside the unit from the measurement signal
system, connecting external devices does not affect the measured values.
The remote commands are the same as with USB.
