Data Acquisition Toolbox

Overview

Data Acquisition Toolbox™ provides functions for connecting MATLAB^® to data acquisition hardware. The toolbox supports a variety of DAQ hardware, including USB, PCI, PCI-Express^®, PXI, and PXI-Express devices, from National Instruments, Measurement Computing, Advantech, Data Translation, and other vendors.

With the toolbox you can configure data acquisition hardware and read data into MATLAB and Simulink^® for immediate analysis. You can also send out data over analog and digital output channels provided by data acquisition hardware. The toolbox includes functions for controlling analog input, analog output, counter/timer, and digital I/O subsystems of a DAQ device. You can access device-specific features and synchronize data acquired from multiple devices.

You can analyze data as you acquire it or save it for post-processing. You can also automate tests and make iterative updates to your test setup based on analysis results. Simulink blocks included in the toolbox let you stream live data directly into Simulink models, enabling you to verify and validate your models against live measured data as part of your design verification process.

Key Features

• Support for a variety of industry-standard data acquisition boards and USB modules
• Support for analog input, analog output, counters, timers, and digital I/O
• Direct access to voltage, current, IEPE accelerometer, and thermocouple measurements
• Live acquisition of measured data directly into MATLAB or Simulink
• Hardware and software triggers for control of data acquisition
• Device-independent software interface

Using Data Acquisition Toolbox to acquire an input signal from a data acquisition board directly into MATLAB. The acquired data is displayed simultaneously as a time-domain signal, an instantaneous FFT, and a waterfall plot, making use of MATLAB signal processing and visualization capabilities.
