GPIB Interface

Communicate with instruments using the VISA-GPIB interface

GPIB is a standardized interface that allows you to connect and control multiple devices from various vendors. Communication is established through a VISA-GPIB object, visadev, which you create in the MATLAB® workspace. For information about creating the VISA-GPIB object, see Get Started with GPIB Interface.

You can write and read both binary and text data. For examples of both, see Write and Read GPIB Data.
