Abstract

We develop methods for assessing the standard uncertainty arising from various combinations of mode-stirring methods used in reverberation-chamber measurements. By use of a straightforward measurement-based technique, the combination of mode-stirring methods that minimizes this component of uncertainty can be clearly identified. We then develop a variance component model that describes this component of uncertainty in terms of physical mechanisms related to the chamber. The model includes the effect on measurement uncertainty of the use of correlated samples and samples having various Rician K factor values. A discussion on ways to minimize these nonidealities is also presented. The techniques presented here allow users to choose the optimal combination of mode-stirring methods for their particular reverberation chamber configuration.
