Data Acquisition Toolbox
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 and other vendors.
With the toolbox you can configure data acquisition hardware and read data into MATLAB for immediate analysis. You can also send out data over analog and digital output channels provided by data acquisition hardware. The toolbox’s data acquisition software 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.
