USB Devices and MATLAB

Many instruments, data acquisition devices, cameras, and other hardware connect to a computer through a USB cable. MATLAB enables you to control and acquire data from these devices using:

• Instrument Control Toolbox
• Data Acquisition Toolbox
• Image Acquisition Toolbox

Interfacing with USB Instruments using Instrument Control Toolbox

Using MATLAB and Instrument Control Toolbox, you can work with any USB instrument that offers remote USB connectivity through VISA software, such as the following:

• Arbitrary Waveform Generator
• Digital Multimeter (DMM)
• Function Generator
• Network Analyzer
• Oscilloscope
• Power Meter
• Power Supply
• Signal Analyzer
• Signal Generator
• Spectrum Analyzer
• Switch

You communicate with these instruments by sending SCPI commands over the VISA-USB interface. Instrument Control Toolbox also provides connectivity through instrument drivers such as:

• MATLAB Instrument Driver
• IVI
• VXI plug&play

You can use these drivers directly from MATLAB to communicate with the instrument over the USB connection, provided that VISA software is installed.

Interfacing with USB Devices using Data Acquisition Toolbox

Through Data Acquisition Toolbox, MATLAB supports many data acquisition devices that connect to the computer via a USB cable, enabling you to work with analog input, analog output, and digital I/O capabilities of these devices directly from MATLAB. See the complete list of supported hardware.

Interfacing with USB Devices using Image Acquisition Toolbox

Through Image Acquisition Toolbox, MATLAB supports many imaging devices and webcams that connect to the computer via a USB cable, enabling you to work with these devices directly from MATLAB. See the complete list of supported hardware.
