Discussion on Regulatory Blind Spots of IEC 61000-4-6 Conducted Susceptibility (C.S.)

In the IEC 61000-4-6 C.S. test, test voltage strength levels such as 1V / 3V / 10V are defined. However, whether these voltage levels—i.e., immunity test voltages—are referenced at the "source" of the generator or at the input of the CDN (after the 6dB attenuator) is unclear. Both interpretations are reflected in the regulatory diagrams, leading to confusion. Here, we clarify and share insights to
