( IEEE Instrumentation & Measurement Magazine , March 2003) Feature Timely publication due to an increase in anechoic chamber installations following FCC-recommended testing of all new electronic equipment for radiated emissions and EM susceptibility. Ideal title to properly understand what the various test facilities can do in terms of electromagnetic testing. Will fill the need for a good specification guide to generate procurement documents, permitting users to develop competitive bids to meet their electromagnetic chamber requirements.
