Abstract
In instrumentation based on an analog-to-digital converter (ADC), the performance of data acquisition (DAQ) device has a direct impact on the performance index of the whole measurement system, so it has an important significance that research the uncertainty analysis of data acquisition board. This paper proposes an automatic measurement system based on DAQ board with automatic uncertainty evaluation of the measurement results according to the "guide to the expression of uncertainty in measurement" and its supplement. Theoretical aspects of the uncertainty analysis in high-speed multifunction data acquisition device and the LabVIEW interface carried out are analyzed and discussed.
