Hi,

As you know, the way that the dummy load resistors are wired for an EMC test can actually drastically effect the scan....the common mode noise can radiate off the dummy load wires , and indeed, from the dummy load resistors.

Why did you not choose a more tight layout of the load in DER472, page 65?, ....ie, so as to reduce load current loop areas..because then you would have got a better  (lower) EMC scan.
