Hello Group, I have a question on the new CISPR22 ammendment that becomes effective 10-2010. It requires free space emission measurements above 1GHz. This is typically done with ferrite absorber on the chamber floor. How does one address this issue when testing on a 10 meter OATS? Are there any site modifications needed? The OATS uses a mesh (chicken wire) for the ground plane instead of solid metal panels. Please also advise if there is any new site validation requirements to do testing above 1GHz. In the past, if NSA is passing below 1GHz, the site would be valid for testing above 1GHz. Thanks, Tim Pierce TAP Engineering & Associates
