Why don't you tell us more about it, and see? I have problems at present with the revision of EN 55103-1 in respect of conducted emissions: the methods in EN 55022 don't suit every type of port. What interest me most about ports is the conducted emission of a good Late Bottled Vintage into my glass. (;-) -- OOO - Own Opinions Only.
