Group, In a large chamber, is emissions testing over 1GHz performed in a "Free Space" setup with absorbers on the floor or it is performed with a reflective floor as has been the method for FCC for years now? What is the current status in this regards? Has a set test setup been established? I am not an expert in CISPR22 or the latest CISPR16 standards. We exclusively use CISPR11 to test ISM equipment which currently state that "Limits are intended to be identical to the limits currently under Consideration for ITE above 1GHz". Are these limits still under consideration and does the test setup require absorbers on the floor? In other words, is emissions testing performed in a Semi-Anechoic Chamber (SAC) or a Fully-Anechoic Chamber (FAC) setup? If floor absorber is required for emissions above 1Ghz, can the same material be used for emissions AND immunity? If not, why? If so, what material do you recommend and where can I buy it? I need to order absorber material for immunity and I would prefer to use something I can also use for emissions if required. Thanks in advance for all replies and any other information that will help me understand the set setup requirements. The Other Brian _________________________
