Abstract

Correlations are an important consideration in the uncertainty analysis of high-frequency electronic systems. We introduce a method to scramble the correlations of a correlated uncertainty analysis and develop a software tool to do this as part of the NIST Microwave Uncertainty Framework. We then compare the results of a correlated uncertainty analysis and the scrambled analysis in estimating the uncertainty in Error-Vector- Magnitude of a modulated signal. This comparison shows that preserving correlations in uncertainties is critical to accurately assessing system performance and uncertainty.
