My latest product went to EMC testing and failed miserably. I run the circuit from 115VAC and a long cord. I will test soon, but my gut says that the noise is comming in on the 115. Has anyone built a circuit(filter) for such a problem? The EMC high freq test is a steel plate driven by a sparking (high power) high freq(>1MHz) noise. I communicate across the 115 and need the low pass filter knee to be around 5KHz. (5k-200k)

I can plunk the values into a calculator and get a filter. But I wanted to know if someone with experience has solved this problem already?

Thank you for your help. Tim
