Controlling GPIB Instruments


This chapter describes specific issues related to controlling instruments that use the GPIB interface. The sections are as follows.
GPIB Overview
Basic features of the General Purpose Interface Bus (GPIB).
Creating a GPIB Object
The GPIB object establishes a connection between MATLAB and the instrument via its GPIB interface.
Configuring the GPIB Address
The GPIB address consists of the board index of the GPIB controller, and the primary address and (optionally) the secondary address of the instrument.
Writing and Reading Data
Interface-specific issues related to writing and reading data with a GPIB object.
Events and Callbacks
Enhance your instrument control application using events and callbacks.
Triggers

Send the GET (Group Execute Trigger) GPIB command to the instrument. This command instructs all addressed Listeners to perform a specified action.

Serial Polls
Execute a serial poll where the Controller asks (polls) all addressed Listeners to send back a status byte that indicates whether it has asserted the SRQ line and needs servicing.
