EMC Diagnostics and Fixes
This one-day seminar provides the fixes to EMC problems that must
be corrected in the later 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. Although emphasis is on existing equipment
that has a problem, the same principles can be applied to new designs to
avoid the problem.
This seminar is intended for EMC engineers and test technicians who
have to fix EMC problems "after-the-fact." Electrical and mechanical
design engineers that want to learn more about fixing EMC problems will
also find this seminar useful.
