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 Input	Acquire data from multiple analog channels of data acquisition device
Analog Output	Output 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

Topics

Timing in Hardware Interface Models
Determine block execution frequency and relate to real-world time.

Featured Examples

Perform Live Acquisition, Signal Processing, and Generation

Acquire live data in Simulink with the Analog Input block, process that data, and send it to a device with the Analog Output block.

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.
