Working with Data Acquisition Toolbox

You can execute Data Acquisition Toolbox functions from the MATLAB command line, through MATLAB applications, or in Simulink models using dialog boxes.

The toolbox provides functions for creating device objects that are directly associated with your hardware. These objects include base properties that apply to all supported hardware, such as sample rate, trigger settings, and channel properties. They also include device-specific properties that let you access the specific features and capabilities of your hardware.

Using Device Objects

Device objects provide a gateway to the hardware's functionality and enable you to control the behavior of your acquisition. For example, you can execute any supported analog input task via an analog input object created in MATLAB or Simulink.

The toolbox supports three device objects: analog input, analog output, and digital I/O. Data Acquisition Toolbox automatically performs A/D and D/A data conversions for receiving or sending data.

Analog Input

The analog input functions let you acquire signals from your hardware. You can create an analog input object, add channels to the object, acquire data to memory, read data into the workspace, and preview the most recently acquired data.

Analog Output

Analog output functions let you send signals out to your hardware. You can create an analog output object, add channels, queue data sets to be output, and generate analog signals.

Digital I/O

Digital I/O functions enable you to generate or read digital signals using your hardware. You can create digital I/O objects, add lines, send data to the hardware, and read data into the workspace.

Channels and Lines

Data Acquisition Toolbox channels and lines are mapped to your hardware's channels and lines. The toolbox supports an unlimited number of channels/lines, enabling you to use as many as your hardware permits.

 

Setup for a data acquisition and analysis session. Data Acquisition Toolbox enables MATLAB or Simulink to interface with the data acquisition boards, such as sound cards.
