What we saw: Most of the folks that attended this meeting had a preconceived idea of what the printers in Larrys talk would look like. You know the kind - small devices one hooks to a PC, sits on a desk , plastic case - that kind of thing. Imagine our surprise then when Larry put his first slide up for all to see. This ain't no common printer folks! A  typical configuration consists of two cabinets 5feet high and 11 feet long and 4 feet deep. Typical uses for the printer would be on-demand books, IRS cheques and so on. These types of  Electromechanical devices present many difficult EMC compliance challenges. Several critical challenges were  discussed such as electrostatic discharge sources within the device, standard EN 61000-3-11 (flicker) and the impact on designs, with a short review of radiated emissions reduction techniques. The presentation concluded with a discussion on the relationship of a product organization and EMC. An organizational example is discussed which was the genesis of an inexpensive radiated emissions solution.
