Data Acquisition Toolbox provides apps and functions for configuring data acquisition hardware, reading data into MATLAB and Simulink, and writing data to DAQ analog and digital output channels. The toolbox supports a variety of DAQ hardware, including USB, PCI, PCI Express®, PXI®, and PXI Express®devices, from National Instruments™and other vendors.
The toolbox apps let you interactively configure and run a data acquisition session. You can then generate equivalent MATLAB code to automate your acquisition in future sessions. Toolbox functions give you the flexibility to control the 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.
What Is Data Acquisition Toolbox?
Voltage and Current
Get Started with Data Acquisition Toolbox to configure, read, write, queue, and log data from data acquisition (DAQ) hardware. Use analog input and output subsystems of DAQ devices to acquire (foreground or background) and generate both voltage and current signals.
