Avoid the Most Common Failures with These 7 Essential EMC Design Rules
A reader recently asked me what the top design rules were that they could implement on their product to maximize the chances of passing FCC and CE testing. There’s no doubt that there are countless ways to fail emissions and immunity tests, but a pattern of failure modes did emerge at my EMC lab.Regardless of the type of product I was testing, be it medical, industrial, … [Read more...]
The First Practical Approach to EMC for Functional Safety (EMC Risk Management)
Keith Armstrong Cherry Clough Consultants Ltd. There are now many standards on Functional Safety (Risk Management) that apply to relevant electronics, including IEC 61508 [1] and the standards developed from it listed in Section II of [2], and ISO 14971 [3]. They all require that EMI be dealt with, but complying with emissions and immunity EMC test standards, even using … [Read more...]

What’s this about CM and DM radiation?
We’ve been discussing loops all along and we are still at it. The last post looked at DM, this time it’s back to CM. These loops are the worst -- big – bad – ugly! Finding the loop may be a problem . . . but where there’s current, there’s a loop. The DM loop is easy, typically a differential pair over a ground plane in a high-speed system, the CM is some … [Read more...]
