What is a data acquisition board? The simplest answer is that it is a basic A/D converter coupled with an interface that allows a personal computer to control the actions of the A/D, as well as to capture the digital output information from a conversion. A data acquisition board is designed to plug directly into a personal computer's bus. All the power required for the A/D converter and associated interface components is obtained directly from the PC bus.

A data acquisition board today is more than a simple A/D function on a board. A data acquisition board can offer measurements of up to 64 channels at a resolution of 16 bits, (one part in 65,536) with data throughput rates up to 20 million samples per second. A data acquisition board often includes discrete digital bi-directional I/O lines, counter timers, and D/A converters for outputting analog signals for control applications.

A data acquisition board designed for high performance will work in a very wide range of test and measurement and control applications. Combined with powerful software, a data acquisition board will turn a personal computer into a powerful measurement system that may be used to automate experiments, construct product test stands, monitor and control production equipment, or be embedded in products ranging from medical monitoring systems to automobile test simulators.
