Effect of Broad-banding Amplifiers on E-field Probe Measurements in a Reverberant Cavity

Abstract

Broad-band electric-field probes have gained wide-spread acceptance for use in reverberation chambers in recent years, primarily due to their ease of use. However, recent work with AOD has highlighted situations where E-field probes may return ambiguous results. In particular, the SR may be greatly affected by the wide-band frequency reception of an E-field probe when in the presence of multiple frequencies in a reverberant environment Monte Carlo simulations conducted to examine the effects of multiple frequencies on probe measurements in a reverberant cavity were compared with experimental data that was taken by an E-field probe that was in the presence of an amplifier exhibiting distortion in a reverberation chamber. The experimental results indicate that considerable care should be taken to ensure frequency purity in a reverberant environment when making E-field probe measurements.
