ATI's Practical EMI Fixes course

This four-day course is designed for technician and engineers who need an understanding of EMI and EMI fix methodology. The course offers a basic working knowledge of the principles of the EMI measurements, EMI fix selection, and EMI fix theory. This course will provide the ability to understand and communicate with communications-electronics (C-E) engineers and project personnel relating to EMI and EMI fix trade-offs.

What you will learn:

Basic EMI Technology
The Fundamentals Of EMI Measurements
Source And Victim Hardening
The Working Language Of The EMI Community
Source And Victim Coupling
The Major Tradeoffs In EMI Fix Performance

Course Outline:

EMI Basics and Units. Definitions. Time and frequency.
EMI Measurements. Time domain and frequency domain measurement techniques, antennas and sensors, and current probes.
EMI Fix Theory. Sources and victims, and coupling paths for conducted and radiated EMI, field-to-wire transition and ground loops.
EMI Fix Selection Flowchart. The methodology for victim identification, access point selection, and coupling path identification. Worksheets for frequency domain measurements and fix selections. Discussion of fix installations and an example application.
The EMI Catalog. An introduction to the catalog, including discussion of layout, fix classification and application guidelines.
Conducted EMI Fixes. A discussion of signal filters for conducted EMI fixes, including power line filters, ferrites, and transformers.
Conducted Transient Fixes. Basic types of transient fixes; spark gaps and transorbs. Controlling stray inducted and capacitive coupling. A discussion on motor generators, uninterruptible power supplies and dedicated power supplies.
Ground Loop Fixes. Techniques to correct ground loop induced EMI.

Speaker and Presenter Information

Dr. William G. Duff (Bill) received a BEE degree from George Washington University in 1959, a MSEE degree from Syracuse University in 1969, and a DScEE degree from Clayton University in 1977. Bill is President of SEMTAS. Prior to being President of SEMTAS he worked for SENTEL and Atlantic Research and taught courses on electromagnetic interference (EMI) and electromagnetic compatibility (EMC). He is internationally recognized as a leader in the development of engineering technology for achieving EMC in communication and electronic systems. He has more than 40 years of experience in EMI/EMC analysis, design, test and problem solving for a wide variety of communication and electronic systems. He has extensive experience in assessing EMI at the circuit, equipment and/or the system level and applying EMI mitigation techniques to "fix" problems. Bill has written more than 40 technical papers and four books on EMC. He is a NARTE Certified EMC Engineer. Bill has been very active in the IEEE EMC Society. He served on the Board of Directors, is currently Chairman of the Fellow Evaluation Committee and is an Associate Editor for the Newsletter. He is a past president of the IEEE EMC Society and a past Director of the Electromagnetics and Radiation Division of IEEE.
