RE: Radiated Emission Measurements above 1GHz
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 is important to remember that using harmonized standards only gives the presumption of conformity.

RE: Radiated Emission Measurements above 1GHz
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 authorities may not believe that due diligence had been applied. So I would start asking - what does the product do - and then find standards that may be useful in making your EMC assessment.

RE: Radiated Emission Measurements above 1GHz
Jim and group, The British Standards version of EN 55022:2006 does not have a section 6.2 and only covers radiated emissions 30 - 1000 MHz. I also have a version obtained >from Dansk Standards that consisted of a list of modifications to CISPR 22 that was attached to CISPR 22 Edition 5.2 (Edition 5:2005 consolidated with amendments 1:2005 and 2:2006. It is my understanding that EN 55022:2006 is a modified version of CISPR 22:2005 without its amendments (the Official Journal listing shows EN 55022:2006 as CISPR 22:2005 (Modified)). As it is the amendments that contain the requirements for radiated emissions above 1GHz, EN 55022:2006 does not go above 1GHz. So, my understanding, is that the significant differences between EN 55022:1998 with amendments A1 and A2 and EN 55022:2006 are the removal of the need for ferrite clamps on cables exiting the test site and the modifications to the ISN requirements for measuring the conducted emissions on telecommunications ports.
