%% Using MATLAB with instruments over GPIB
% MATLAB supports GPIB communication only when you use it with the
% Instrument Control Toolbox. There are many instruments with a GPIB
% interface including oscilloscopes, arbitrary waveform generators (AWGs),
% function generators, and signal analyzers.
% The Instrument Control Toolbox provides a graphical tool that allows you
% to configure, control, and acquire data from your instrument without
% writing code. The tool automatically generates MATLAB code that allows
% you to reuse your work. The code example below was automatically
% generated by the tool. Type "tmtool" at the MATLAB command line to
% launch this tool.
% This code example below shows you how you can communicate with your
% instrument using MATLAB. The "*IDN?" command was used which is a
% typical command for querying an instrument to identify itself. The
% commands you can use will depend on what your instrument supports.
% An Agilent GPIB driver was used here. A list of other GPIB drivers is
% available at:
% The toolbox also supports serial, TCP/IP, UDP and communication
% protocols, IVI and VXIplug&play instrument drivers, and LXI instruments.
% (Not shown here).
%% Automatically generating a report in MATLAB
% Press the "Save and Publish to HTML" button in the MATLAB Editor to
% execute this code example and automatically generate a report of your
% work with the instrument.
%% Automatically generating MATLAB script for your instrument
% To automatically create your own MATLAB script, launch "tmtool". Open the
% "Hardware" node, open the "GPIB" node, scan for GPIB drivers (right click
% on GPIB to do this), and press the "connect" button. Once connected,
% enter your device commands in the right pane, press "Session log" to see
% the code generated, and press "Save Session" to save the code to a
% MATLAB (.m) file.
%% MATLAB script automatically generated for the instrument
% The following MATLAB script was automatically generated by interacting
% with the configuration tool provided by the Instrument Control Toolbox.

% Create a GPIB object.
obj1 = instrfind('Type', 'gpib', 'BoardIndex', 7, 'PrimaryAddress', 10, 'Tag', '');
% Create the GPIB object if it does not exist
% otherwise use the object that was found.
obj1 = gpib('AGILENT', 7, 10);
obj1 = obj1(1)
% Connect to instrument object, obj1.
% Communicating with instrument object, obj1.
data1 = query(obj1, '*IDN?');
% Disconnect from instrument object, obj1.
% Clean up all objects.
