Dear Muriel, The Differential- or Common-mode Box design is in the IEEE Transactions on EMC, Vol. 30, No.4, November 1988, pages 553-560. Figure 2 shows the schematic and Figure 3 has an inside picture. The box is very easy to make. It is made from two transformers, two resistors, and a

Dear Muriel Separating CM from DM at the output of a LISN was covered by Michel Mardiguian and Joel Raimbourg in a paper they presented at the IEEE EMC Symposium held in Seattle in August 1999, titled: An alternate, complementary method for characterising EMI filters (Volume 2 of the Symposium
