I’ll try to get some photos tomorrow. And plots.

Can you share some photos or screen captures? Usually there will be a difference between DM and CM current spectral response. Now Line and Neutral from a LISN will like look the same typically.

Right now, the plots of CM and DM currents are almost equal over the whole spectrum (10k – 30MHz). Surprise? In the same setup, using a LISN, the spectrum is quite different regarding peaks and waveform. I know the information from this test is defective, but do you have a first thought anyway?
