Abstract
Measurements results and chamber characteristics are reported for the N P L stadium re-verberation chamber in mode-tuned operation., using a miniature 3-axis electric field sensor. Results are based on the analysis of the measured stirrer data for the magnitude of the electric field, for mechanical wall stirring, at 2.5 Hz and 8.2GHz. The measured probability distributions and various associated sample statistics are compared with theoretical results for ideal chambers, showing excellent agreement. The present study confirms and extends earlier results which were based on the measurement of power density. In addition, total field anisotropy and field inhomogeneity levels are obtained from the field probe data, quantifying the reverberation performance. Some new theoretical results are also derived.
