EMUE-D6-6-DAQBoardElectricalQuantities

Measuring chains based on a data-acquisition board installed in a personal computer or a micro-controller-based board This example refers to the measurement of the magnitude of an electrical impedance by comparison to a standard resistor. The voltage signals across the impedance and the standard resistor are acquired by means of a multiplexed data-acquisition board. The measurement uncertainty is estimated according to the GUM framework. Experimental results that refer to the cross-talk characterization of a commercial data-acquisition board are also reported.
