Ghery, Rob, all Remember that when you apply a standard you are doing so on the basis that the standard covers ALL the product EMC characteristics. IF you design a PC with a 3GHz clock and only apply a standard with a 1GHz limit and then there is a problem with real interference at 3GHz, the

Tim - true enough, and as Engineers we can't disagree from a technical perspective. However, manufacturers are going to test only to what they HAVE to test to, i.e. there is a presumption of conformity with the EMC Directive if the manufacturer applies those standards published in the OJ that

Way back in 2003 this issue was addressed in an ECACB (now ECANB) Technical Guidance Note (TGN 9), which we've been using since then. Basically it states that if a product has the potential to interfere at frequencies above 1GHz, it should be checked using appropriate limits and test methods. It
