What To Do If a Product Fails in the EMC Lab

Abstract

It is a fact of life that products will fail in the EMC test laboratory once in a while. Regardless of whether designers apply all the design strategies explained in this book or not, sometimes events occur that are outside our control. For example, a subsystem is purchased from a vendor and installed in our system. It works fine in other systems, but there is a problem when installed in our system. A shielded enclosure may not be quite as “tight” as planned, etc. The list of things that can go wrong is endless, and to be effective in the testing phase, laboratory engineers must quickly find the source of the problem and propose one or more solutions.
