A number of requirements must be fulfilled before measurement uncertainty analysis of signals from transducers is justified. These requirements include good measurement system design practices such as adequate low- and high-frequency response and data-sampling rates, appropriate anti-aliasing filter selection,1 proper grounding and shielding, and many more. Numerous textbooks contain procedures for performing uncertainty analysis2 to assign accuracy bounds to measured data. These bounds can easily be established if the measurement system operates in a fixed environment. However, many testing e...
