Mike, Nothing in ANSI C63.4 or CISPR 22. This is a known weakness in both committees and it will be worked. Just can't say when. The new version of C63.4 (coming out soon) does not yet address this. There is nothing going on in CISPR SC G to add this to CISPR 22. I would suspect that CISPR SC A is working on something, but I'm not in their working groups, so I can't say for certain.
Right now the guidance is that if a site meets NSA below 1 GHz, you may use it above 1 GHz. There are known problems with this approach, but it's the best we have to work with at this time. Ghery S.

I'm specifically interested in whether or not ANSI C63.4 or CISPR-22 is planning this, and if so, is there any preliminary info? Any help would be greatly appreciated.
