At a former employer, we finally ended up putting resistive load banks in
computer chassis' (as shielding) for testing power supplies. But we found
that power supplies can fail at full load from their own emissions, and
later, installed in working equipment at lower loads, due to passing

Greetings all,
Sorry for the late reply - summer :o)
I have done some work with cell phones and have found that certain

Specifically, I had reason to measure emissions of phones from several
