Data acquisition is the sampling of the real world to generate data that can be manipulated by a computer. Sometimes abbreviated DAQ or DAS, data acquisition typically involves acquisition of signals and waveforms and processing the signals to obtain desired information. The components of data acquisition systems include appropriate sensors that convert any measurement parameter to an electrical signal, which is acquired by data acquisition hardware.

Acquired data are displayed, analyzed, and stored on a computer, either using vendor supplied software, or custom displays and control can be developed using various general purpose programming languages such as BASIC, C, Fortran, Java, Lisp, Pascal. Specialised programming languages used for data acquisition include, EPICS used to build large scale data acquisition systems, LabVIEW, which offers a graphical programming environment optimized for data acquisition and MATLAB provides a programming language but also built-in graphical tools and libraries for data acquisition and analysis.

      Fast-UXGA Frame Grabber Series

      The Fast-UXGA frame grabber series is for users who anticipate a demand for extreme I/O requirements or higher bandwidth, complex image processing and real-time fast storage in a cost effective platform. The base Fast-UXGA, is a raw-length PCI board with two (four-mixed) UXGA analog conversion channels using Analog Device's AD9888. The front end data is formatted and preprocessed by a FPGA before being sent to the memory subsection, processor, GigE interfaces or other outputs. Finally, the Fast-UXGA interfaces to the host computer through a PCI-X or 4x PCIe interface for state-of-the-art data acquisition. Options include the addition of multiple (8) Serial ATA (SATA) 150 MB/sec interfaces for continuous high-speed data storage without the usual OS or host bus transfer delays.
