Abstract: The probability density function (PDF) of the error is derived for several frequencies, taking different source impedances of the EUT into consideration. The assumption of a triangular distribution cannot be confirmed. It is shown that the coverage interval is not always correlated to the minima and maxima of the PDF, as it is for the worst case analysis. The phase requirement for the AMN impedance is questionable, since the probability for the circumstance where a problem really occurs is neglectable. Further efforts must be put in the improvement of the measurement model, since the results heavily depend on the assumption of the EUT source impedance.
