Description
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.
Files contained in the dataset are:

Notes
The results reported in the example refer to the data that have been assigned in the MATLAB script unc_zx.m. Other input data can be used accessing to the variables in the script according to the instructions explained in the help section of the script.
The experimental results that refer to the characterization of the cross talk between adjacent and non-adjacent channels of a commercial DAQ board have been obtained with the set-up described in the paper: A. Carullo,
S. Corbellini, A. Vallan and A. Atzori, Uncertainty Issues in Multi-Channel Data Acquisition Systems, in Proceedings of IEEE 2020 I2MTC Conference, May
