Simulink Data Acquisition

Build models to acquire and generate analog and digital data

The Data Acquisition Toolbox™ block library provides a set of blocks for performing analog and digital signal generation and acquisition in Simulink® models.

Blocks

Analog InputAcquire data from multiple analog channels of data acquisition device
Analog OutputOutput data to multiple analog channels of data acquisition device
Analog Input (Single Sample)Acquire single sample from multiple analog channels of data acquisition device
Analog Output (Single Sample)Output single sample to multiple analog channels of data acquisition device
Digital Input (Single Sample)Acquire single sample from multiple digital lines of data acquisition device
Digital Output (Single Sample)Output single sample to multiple digital lines of data acquisition device

Perform Live Acquisition, Signal Processing, and Generation

Perform Live Acquisition, Signal Processing, and Generation

Use the Analog Input block to acquire live analog data from a data acquisition device into Simulink. The acquired data is processed in Simulink and uses the Analog Output block to output data to a data acquisition device. It shows how a Simulink model can communicate with different subsystems in the same model. In this case, the data acquisition device used is from National Instruments®.

Perform Spectral Analysis on Live Data

Perform Spectral Analysis on Live Data

This example shows how to use the Analog Input block to acquire live signals from a data acquisition device into Simulink. The block uses a National Instruments(R) USB-6211 as the input device. The Simulink model uses a spectrum estimator to output a power spectrum estimate of a time-domain input using Welch's method of averaged modified periodograms.
