The FCC rules require measurements up to 2 GHz when the base frequency is 108 MHz or greater, but I don't know of an equivalent requirement in EN documents. Perhaps others can shed light.
Gabriel Roy Hughes Network Systems MD --------------------------- snip ------------------------ The EN55022 and EN55011 standards do not show (as far as I have been able to find) emission limits over 1Ghz. Does anyone know how we are to test products with fast clock speeds whos harmonic could cause emissions problems over 1Ghz in Europe? Are newer versions of the standards coming out which may address this? If so, any idea of what the limits might be? Thank you, Brian Kunde LECO Corp.
