Hi all, Our experience is that you get pretty much the same levels with either a reverberation chamber, or with high gain antennas in a regular anechoic chamber. It is possible to increase the antenna gain by 3 or 4 dB compared to "traditional methods", and get up to the same levels achieved in a reverberation chamber. Our methods achieve a minimum 3000 V/m, 1-18 GHz in a regular anechoic chamber.

This allows you to get higher E-fields for a test like RS103 than you could get using traditional methods. <snip> Ed Price WB6WSN Chula Vista, CA USA From: Pat Lawler [mailto:[email protected]] Sent: Sunday, April 28, 2013 7:38 AM To: [email protected]<mailto:[email protected]> Subject: [PSES] Mode-stirred, Mode-tuned, Reverb - what's the difference? All, Over the years, I've come across pictures of test chambers with descriptions such as mode-stirred, mode-turned, and reverberation. They seem to look similar, with metal walls and rotating metal paddles. Do these names reference the same basic design, or are they different animals? Which ones are used for which type of RF immunity test?
