EMC Testing above 1 GHz: The Deadline Looms
When first mandated in the 1990s, the stated objective of the EU’s Directive governing EMC was, in broad terms, that commercial and domestic equipment, and certain industrial systems, should neither cause interference or be susceptible to interference. They should not emit radiated or conducted energy at RF frequencies and they should be immune to such emissions, within … [Read more...]
