ELECTROMAGNETIC COMPATIBILITY SEMINAR SERIES


One-day EMC seminars provide an opportunity to go into more depth, than do multi-day seminars, and cover only a single topic.  Each topic listed below can be presented as a one-day seminar.  These are usually presented in-plant at your location (within the continental US).  Occasionally we also present some of them as public seminars.

Partitioning & Layout of Mixed-Signal PCBs

  Preventing digital logic currents from contaminating low-level analog signals on a mixed-signal PCB can be a difficult problem, especially on boards with multiple ADCs. This one-day seminar looks at the various approaches for dealing with this problem. The advantages as well as the pitfalls of split ground planes are examined.  The presentation concludes that component placement, partitioning, proper PCB topology, and routing didciplin are the keys to success.  Outline of Partitioning & Layout of Mixed-Signal PCBs.
 

EMC Systems Design Workshop

 This one-day workshop discusses the systems approach to EMC design and takes the participants through the EMC design of a product from start to finish  A hypothetical digital product is used as the workshop example. It is desirable, but not required, for participants to have some basis EMC design background.  Outline of EMC Systems Design Workshop.
 

Antenna Theory Simplified

If you would like to understand how antennas work, but lack the time or desire to study the intimidating mathematics normally associated with antenna theory - this course is for you. Circuit theory (instead of field theory) is used to analyize antenna operation.  This produces simple but accurate circuit theory models that gives the participants an intuitive understanding of antenna operation. .  Outline of Antenna Theory Simplified Seminar.

Cabling and Grounding

EMC systems considerations as well as the basic EMC subjects of cabling and grounding are covered.  Emphasis is on applying the systems approach to EMC early in the design.  Cable coupling mechanisms, and the importance of cable shield terminations are discussed.  The purpose of grounding, as well as an EMC grounding philosophy are presented.  Outline of Cabling and Grounding Seminar.
 

Basic Digital Design

The EMC concerns for  digital logic systems operating with clock frequencies up to a few hundred MHz are covered.  Important design parameters and printed circuit board layout features, including the characteristics of different ground structures and various methods of decoupling are discussed.  In addition, models are developed for both differential-mode and common-mode emission mechanisms.  Other topics include transmission line matching and radiation, and the use of an „image planeš to reduce radiated emissions. Outline of Basic Digital Design Seminar.
 

Decoupling & Grounding of High-Speed Digital Circuits

Covers the mechanisms by which digital logic circuits generate power supply noise, and the effectiveness and limitations of the various approaches to decoupling and grounding.  New technology to overcome the limitations of traditional decoupling methods will be discussed.  The characteristics of ground planes, the significance of ground voltage drop, and methods of minimizing it are also discussed.  This seminar duplicates some material found in the Basic Digital Design seminar.  Outline of Decoupling and Grounding of High Speed Digital Circuits Seminar.
 

Common-Mode Filter Design

Explains why common-mode filter design is different than differential-mode filter design.  Filters are designed using the graphical attenuation method.  This graphical method allows the designer to calculate and understand the effects of varying load and source impedances, and to design complex filters one stage at a time.  Another advantage of this method is the ease in which parasitic and complex component characteristics can be handled.  Outline of Common-Mode Filter Design Seminar.

EMC Diagnostics and Fixes

 Discusses fixes to EMC problems that must be corrected in the late stages of a product‚s development.  The speed that the fix can be implemented is emphasized over the cost of the changes.  Diagnostic techniques to determine the necessary solutions are also covered.  Fixes for both radiated and conducted emission problems are presented. Outline of EMC Diagnostics and Fixes Seminar.
 

Workbench EMC Measurements

This seminar covers simple EMC measurements that designers can use in their own lab, without the need for an elaborate EMC test facility.  Measurements can be used to estimate or predict the EMC performance of a product. Outline of Workbench EMC Measurement Seminar.
 

High Frequency Measurement Techniques

Covers proper high frequency measurement techniques and philosophy.  Special attention is paid to high frequency scope probe effects, current probes, and pickup loops.  Proper measurement techniques and inexpensive, easy to build, high frequency probes are described.  About 50% of the class time is spent doing experiments and demonstrations.  The instructor for this course is Doug Smith, author of the book High Frequency Measurements and Noise in Electronic Circuits This seminar is also offered in a two day format, with additional demonstrations and more indepth discussion of the various techniques.  Outline of High Frequency Measurement Techniques Seminar.
