EMC Troubleshooting Techniques
Kenneth
Wyatt, Sr. EMC Engr Tuesday, August 24, 2010 Abstract:
Because
time-to-market and budget factors often drive many of today’s high-tech
designs, electromagnetic compatibility (EMC) issues often surface at the
last moment in the design cycle, potentially delaying product introductions.
It's important to be able to troubleshoot these issues quickly and
efficiently. We'll cover simple probing techniques using low-cost
instrumentation to help determine the issues, as well as covering an
efficient troubleshooting philosophy.
Bio:
Kenneth Wyatt, Sr. EMC Engineer, Wyatt
Technical Services, LLC, holds degrees in biology and electronic
engineering and has worked as an product development engineer for 10 years
at various aerospace firms on projects ranging from DC-DC power converters
to RF and microwave systems for shipboard and space systems. For over 20
years, he has worked as a senior EMC engineer for Hewlett-Packard and
Agilent Technologies in Colorado Springs where he provided comprehensive
EMC design and troubleshooting services.
A prolific author and presenter, he has written or presented topics including RF amplifier design, RF network analysis software, EMC design of products and use of harmonic comb generators for predicting shielding effectiveness. He has been published in magazines such as, RF Design, Test & Measurement World, EMC Design & Test, Electronic Design, Microwave Journal, HP Journal and several others.
Kenneth is a senior member of the IEEE
and a long time member of the EMC Society where he serves as their
official photographer. His comprehensive, yet practical, EMC
design, measurement and troubleshooting seminars have been presented
across the U.S., Europe and Asia. Ken may be reached at ken@emc-seminars.com.
