Under ANSI C63.4 2009 you are to test with the absorbers above 1GHz, but if the lab uses ANSI C63.4 2003 you CANNOT use the absorbers. Under ANSI C63.4:2009 the minimum attenuation for the absorbers must be 20dB and cover a 2.4 m by 2.4 m square.

The test lab I use has absorbers on the ground plane meeting the CISPR 16-1-4:2007 VSWR requirement up to 6GHz. ANSI says absorbers are acceptable above 1GHz as long as the setup is meeting the CISPR 16-1-4 requirements. Does this mean I can run an FCC test from 1-40GHz with these absorbers in place?
