Repeatability of computer-corrected network-analyser measurements of reflection coefficients

Abstract
Practical results relating to the accuracy of 100 sets of repeated reflection-coefficient measurements using a computer-corrected network analyser are given. Statistical data based on the above sets of measurements are presented. The results show that measurement accuracies of 1% can be predicted with a confidence level of 99%. A method of dealing with the possible occurrence of ‘rogue’ measurements is discussed.
