I have a problem with the test "Injected current" (under standard 61000-4-6).
The source of disturbance (AM wave modulated), is injected along the 115 Vac power line and propagates along the entire chain of supply (+12 V, +5 V and GND) of PCB. I tried to filter it with a common mode inductors, capacitors and low-pass filters, but without a minimum result. What can I do?
