I'm currently reading about EMC standards, ACMA/FCC/CE compliance. I'm just looking at the description of "AS/NZS 61000.6.3-2012" haven't bought it yet. It says:
"Adopts IEC 61000-6-3, Ed.2.1 to specify emission requirements in the frequency range 0 Hz to 400 GHz for electrical and electronic apparatus intended for use in residential, commercial and light-industrial environments."
Seems pointless even buying it for me given that the frequency range goes to 400Ghz! I haven't looked, but I'm sure a spectrum analyser with that kind of bandwidth would cost as much as a house. Can anyone shed some light on this? How can a standard intended for the broadest category of consumer goods require testing to such high frequencies? It would make most useless trinkets economically nonviable to develop, yet there's so much stuff on the market. Confused!
