Ray, Did you consider using Reverberation Chamber (RC) instead of semi-anechoic chamber for pre-compliance? It seems to me that RC technique has become practically applicable for both emission and immunity tests. It's less expensive. Official EMC standards would accept it in a couple of years. "IEC 61000-4-21: Reverberation Chamber" is circulating for comments.
I know little about RC and expect some knowledgeable colleagues to make comments.

I was planning on a 3m shielded room with the possibility of making it semi-anechoic when the budget allows. Our products are large (relative to normal ITE equipment) with the largest that would be tested in the chamber 10ft wide X 6ft long X 3ft high. I have most of the equipment I need to do the tests for EN 55022 and EN 50082. I need a motorized antenna mast that goes from 1-4m and a chamber. If anyone could direct me to a person or company selling the chamber or antenna mast I would greatly appreciate it. Also I would like to get some feedback on the Cassper virtual chamber and if anyone has used it or has comments on the usability of such a system.
