During consulting assignments, I constantly see engineers struggle to achieve EMC compliance, either emissions or immunity. This not only includes regulatory approval and functionality but also managing an in-house system that may not have been designed to include EMC and safety approvals. They…

We need to maximize the functionality of a product using printed circuit boards while at the same time shrink the physical size along with lower cost of development and production. We are discovering that signal integrity is becoming a greater concern…

There must be a source, path and receptor for an EMC event to occur. If a radiated or conducted problem is observed during compliance testing, how do we quickly locate the source of undesired RF energy? Many engineers will start…
Many electronic products generate electromagnetic interference (EMI). Digital devices may emit undesired RF that could interfere with the operation of other electrical devices and systems located within close proximity. Mixed signal components (digital and analog) are both used on printed circuit…
We attempt to ensure products comply with regulatory requirements, both safety and EMC. With regard to EMC, compliance engineers always seek an elusive 3 dB margin, yet if we are a few dBs over the specification limit does this mean the…
