Thanks to all who have responded so far. One note of clarification: we are already set up for doing ESD testing in-house, and I agree that's where most of our failures will happen. I also agree that much of the immunity suite will take care of itself on a well designed unit that has low emissions, but I don't think that's true with surge. Maybe EFT, but not surge.
Note: please refrain from replying both to me and to the forum - you only need to reply to the forum. I suspect some, but by no means all, of our "double-posting" complaints stem from people sending 2 replies. Having said that, I am getting 3 of everything this morning! Thanks, Jim Eichner, P.Eng.
