Bob Yes I should have tried that approach.
Thanks for pointing it out. I do have another opportunity in a few months.

It would seem to me that if you test the DC input and it passes, then there should be little question about compliance.

We planned to recommend a particular class B power supply with this device. However the noise from our device appears to be pushing through the power supply and limiting the combo to class A. The problem area is in the 5-30 MHz. range. So now I need to resolve if the power supply by itself is the issue or if our device is the culprit. Radiated wise I can achieve class B with this combo.
