RE: EN 55022:1998 plus A1:2000

In a previous life I had a similar problem. That is: How to add ferrites to damp emissions that were NOT EUT generated without violating the intent of the emissions specification. In my case I had numerous (~20) shielded cables that went through a patch panel up to the measurement area. The

Hi Derek - Go Reds!! This is not a surprise to me. I have railed at much length a couple of years ago as to the latest FCC changes to the emissions qualification. I am sure you are familiar with it so I won't belabour the point. Fundementally the FCC PC emissions procedure has rendered the EMC
