Multi-Day EMC Seminars

These two or three day seminars are similar to the three-day public seminar.  However, they are  presented at your location (within the continental US) and cover the practical aspects of noise and interference control in electronic systems.  Cost effective EMC design, and the importance of the systems approach early in the design are stressed.

Each module listed below is presented in a 1-1/2 hour session. Four modules can be presented in one day.  You, therefore, can pick and choose the modules that are of most interest to your group.  Cabling,  Shielding, and Grounding of Mixed Signal PCBs can be expanded and presented as double sessions (3 hours).

A two day seminar will consist of eight (8) modules, whereas a three day seminar will consist of twelve (12) modules.

 The multi-day seminar notes for each participant are placed in a 3-ring binder and a copy of the book Electromagnetic Compatibility Engineering, by Henry W. Ott is included for each person attending the seminar.

  EMC Training and Product Review:  You may want to consider combining one of our multi-day EMC training sessions with a half- or one-day of EMC consulting.  After learning the important principles of EMC, apply them by  sitting down with the instructor for a one-on-one EMC review of your product.

Product Design Review

* Standard three-day seminar, cabling is presented as a double session.

The above recommendations represents our standard three day offering, however, if  you prefer a different combination of subjects that can be accommodated, just pick any twelve modules from the above listed subjects to form your own customized three day seminar.
