Morning folks, A few weeks ago I asked for help finding a quiet MB. Well, I finally have got boards in and tested.
I can't name names on the list, but, the best MB came from a US, Vancouver based company. Two big problems with ALL MB's. Plug in a PS/2 mouse, and the emissions dramatically increase. Also, this happens with the KB too. It would seem that the designers of the boards put a switched mode power supply right next to the connectors: not a smart move in my opinion. Anyway, this leads me to another question where I could do with some guidance: I'm testing a device that basically does HI-Pot testing on electrical equipment. What classification of equipment is this, and what product standard would I use to specify the EMC tests to run? I can only believe that this is light industrial equipment. Thanks, Derek N.
