Quick Start Guide — Using MATLAB with Agilent U2300A DAQ Devices 1
1 Introduction
MATLAB® Data Acquisition Toolbox is a well known data analysis
software environment and programming language. MATLAB software
enables you to configure, control, and acquire data from the U2300A
Series USB multifunction data acquisition devices. Once data is in
MATLAB, you can analyze and visualize that data using interactive tools
and command- line functions for data analysis tasks such as signal
processing, statistical analysis, digital filtering, and curve fitting. MATLAB
is also used for generating waveforms and developing Test & Measurement
applications.
MATLAB supports the U2300A Series USB multifunction data acquisition
devices using MATLAB, MATLAB’s Data Acquisition Toolbox, and a
software adaptor. The models in the U2300A Series family that are
supported are the U2351A, U2352A, U2353A, U2354A, U2355A, U2356A,
and the U2331A.
In order to use these devices with MATLAB, you need to install MATLAB
and Agilent software components and applications, connect the USB
multifunction DAQ device, install the respective drivers, and verify the
whole operation with the MATLAB example for U2300A Series hardware.
These steps are described in this document.

Launch MATLAB.
1 Click File > Set Path. The Set Path window appears as shown.
12 Quick Start Guide — Using MATLAB with Agilent U2300A DAQ Devices
2 Click Add Folder. The Browse For Folder window appears as shown. Use
this window to locate the AgilentU2300.dll file. The default
MATLAB DAQ Adaptor directory is C:\Program Files\Agilent\
DAQMATLABAdaptor.
3 Click OK. The folder is then added. Click Save and then click Close.
4 Open the MATLAB example program. Change the AgilentU2300 name to
the name of your adaptor by editing the program. Then run the
example program. Your output should look similar to the example
shown below.
5 Once you add the .dll file to the path in the steps above, you need to
register it. (This is a one time step.) You can register the .dll in the
MATLAB Command Window: daqregister(‘C:\Program Files\
Agilent\DAQMATLABAdaptor\U2300 Series\AgilentU2300.dll’)
6 Execute the MATLAB example program called “daqstartup” in the
MATLAB Command Window to confirm that everything is installed
correctly. (You can download this example application at
http://www.agilent.com/find/matlab_u2300A.) Your output should look
similar to the results shown below:
