Short summary
Test setups required for different immunity test methods based on ISO 11452-2 (ALSE) and ISO 11452-4 (BCI) are similar. However, lack of knowledge regarding the impedance of the tested component, makes it impossible to find the equivalent current to be injected by the BCI probe and a good match cannot be achieved. In this paper, three approaches are proposed to estimate the termination impedance indirectly by using different current probe.
