Please correct me, if I am wrong (that happens quite often …): * Let one wire (L) pass through a current clamp, and you measure the combination of current mode and differential mode currents
* Do the same with wire N. If L and N are (almost) equal, you either have major part of DM currents or major part of CM current * Let both wire (L and N) pass through a current clamp, and you measure the only CM current (DM is canceled) * When doing conducted emission test by LISN, you actually get what you get. LISN do not see the difference between CM or DM. From LISN measurements, you can’t say if noise is CM or DM.
