Data acquisition and instrumentation
solutions using MATLAB
The Data Acquisition Toolbox and the Instrument Control Toolbox enable users to connect to hardware and instrumentation and collect, analyze, and model real-world data -even execute entire test procedures -completely in MATLAB. The MathWorks partners with leading providers of measurement systems to ensure that these toolboxes support the most popular data acquisition and instrumentation systems with a consistent yet extensible interface. Some of the market-leading measurement system providers that support the Data Acquisition Toolbox and Instrument Control Toolbox are described here.
IOtech produces the DaqBoard/2000, a high-speed, multifunction, plug-and-play data acquisition board for PCI bus computers. It features a 16-bit, 200-kHz A/D converter; digital calibration; bus mastering DMA; two 16-bit, 100-kHz D/A converters; 40 digital I/O lines; four counters; and two timers. Up to 470 channels of analog and digital I/O can be accessed with one DaqBoard/2000, and up to four boards can be installed into a PC. A 100-pin connector on the DaqBoard/2000 provides access to all the input and output signals and accommodates all I/O with one cable and one PCI slot. The onboard scan sequencer lets users select up to 512 channel/range combinations, while bus mastering enables analog and digital I/O data to flow between the PC and the DaqBoard/2000 without consuming CPU time. IOtech's adapter for the Data Acquisition Toolbox enables users to bring data directly into MATLAB using the DaqBoard/2000. In addition, IOtech's GPIB interface boards work with the Instrument Control Toolbox to enable direct connection with GPIB-compatible instrumentation and devices, including IOtech dataloggers.

Keithley Instruments makes data acquisition boards that provide a wide range of functionality, including analog I/O, digital I/O, and counter/timers for a variety of computer hardware. Multifunction analog I/O boards enable the control of closed-loop processes by switching relays and controlling setpoints. Digital I/O boards enable system integrators and OEMs to control processes, monitor the status of control points, turn power on and off, and meet high-channel-count requirements. Analog output boards enable control and process engineers to control valves, gauges, and other analog devices that require voltage or 4-20mA current. The Data Acquisition Toolbox enables MATLAB users to communicate directly with Keithley data acquisition boards, offering a consistent interface while providing access to the advanced features of each board. Additionally, Keithley GPIB-compatible instruments can be accessed and managed using the Instrument Control Toolbox and a compatible GPIB interface card.

United Electronic Industries offers the PowerDAQ PCI- and PXI-based data acquisition products for acquiring instrument-grade, real-world data directly in MATLAB using the Data Acquisition Toolbox. The PowerDAQ cards plug into the PCI or PXI/compact PXI bus and can digitize analog inputs with instrument-grade quality, generate analog outputs, and work with digital I/O. The MF Series multifunction cards use an onboard DSP to enable simultaneous full-speed operation of analog I/O and digital I/O subsystems. The MFS Series of simultaneous sampling boards dedicate high-precision analog circuitry to each input to guarantee true simultaneous sampling at rates of 2M samples/sec.
