What is the Number One Item That Causes EMC Problems at the Board Level?
There are many “rules” for laying out a printed wiring board (PWB) to minimize generation of EMI from a board. These cover a wide range of issues that are important. Some more than others, but all can be important. But, if you were to ask what the number one item on the hit parade would be, what would you say? What are the important factors to consider when laying out a … [Read more...]
UNECE Regulation 10: Electrical/Electronic Sub-Assembly Radiated Emissions Testing (Annexes 7 and 8) and Radiated Immunity Testing (Annex 9)
In this installment in the series of blogs on UNECE Regulation 10, Revision 5, Amendment 1 (8 October 2016), hereafter referenced as R10.05, we will look at radiated emissions and immunity testing of Electrical/Electronic Sub-Assemblies (ESAs). ESA RADIATED EMISSIONS (Annexes 7 and 8) Like the vehicle radiated emissions testing annexes, R10.05 has separate … [Read more...]
Oh How I Hate to Commutate!
My favorite Sophomore in Engineering, Roger, and his group, made a small crane for their engineering project. It had many EMC issues. One issue they had was noise from permanent magnet DC motors. I am so glad Roger cares about this issue, because I have modeled a few permanent magnet DC motors, and I can explain how to design it so that then so they are … [Read more...]

UNECE Regulation 10: Worst-Casing
Before applying for a new Type Approval, or extension of an existing certificate, the applicable tests must be agreed with the Technical Service. A later blog in this series will cover the subject of approval extensions, so for this post we will consider new approvals. Where a manufacturer has multiple variants and/or configurations, worst-casing can significantly reduce … [Read more...]
UNECE Regulation 10: Conformity of Production
In this second blog in the series on Type Approval to UNECE Regulation 10, Revision 5 we will cover the subject of Conformity of Production (CoP) and explain why it is a critical part of the Type Approval process. The requirement for CoP is a fundamental element of the 1958 Agreement and the procedure is set out in Schedule 1 therein. Approval Authorities are required to … [Read more...]
New Application Note! Integrated Circuits (ICs) and Component EMC Testing
Sponsored by AR RF/Microwave Instrumentation In every product sector, emerging technologies (IoT,5G, drones, automobiles, and others) rely increasingly on efficient electronic components for critical operation. There is a growing concern on their performance and co-existence in the presence of an electromagnetic environment. By following the techniques outlined in this … [Read more...]
