I am looking for advice as I prepare for radiated emissions testing above 1 GHz according to the CISPR test method, which becomes mandatory in 2010.
I have an OATS with an all weather fiberglass dome (with a 4m diameter turntable) in which I test ensembles of floor-standing racks of equipment (each rack ~6 ft high, 2000 lbs.) Does anyone have recommendations to share with me as to candidate absorber materials for placement on the floor to meet the CISPR 16-2-3 measurement method for measuring radiated emissions above 1 GHz? I am guessing that important characteristics for absorbers may be: fragility or durability, absorption frequency range, cost, and size. I cannot easily raise my EUT to a height off the floor to clear the absorbers, not can I configure my EUT to place certain chassis higher or lower in the rack. I appreciate your help in advance.
