Utilizing Reverberation Chambers as a Versatile Test Environment for Assessing the Performance of Components and Systems

Abstract

Electromagnetic reverberation chambers have been used for many years by the Electromagnetic Compatibility (EMC) community to measure the susceptibility and emissions for various electronic components and systems. This presentation describes how statistical processes were used to reduce the uncertainty of these chambers to a level necessary for precision metrology applications. These processes were applied to the calibration of electromagnetic field probes and the assessment of antenna efficiencies. A brief comparison of traditional calibration methods employing transverse electromagnetic (TEM) cells and anechoic chambers to the new statistical reverberant environment will be shown.
