Selecting a multifunction data acquisition board for a computer-based measurement system

Abstract

Totally automated measurement systems are the norm for manufacturing test, research and any other areas where measurements are made. Measurement automation leads to extensive data sharing, inter-instrument communication, and remote measurement control. Multifunction data acquisition (DAQ) devices meet these measurement needs. Designed to meet the needs of a general-purpose measurement system leveraged with a computer, DAQ devices provide features such as analogue input, analogue output, digital input, digital output, and counter-timer functionality. This paper introduces the basics of a DAQ board and provides the reader with information on how to evaluate a DAQ product for use in a computer-based measurement system.
