I can't answer your first question, but for the second question you
should look at EN 50715, which advises that you should determine the
margin by applying statistical methods to data obtained from
measurements of similar products. It isn't safe to assume 3 dB.

Hi there,
A question came up that I can't answer w/o a copy of Part 47.
Does the FCC report require Quasi-Peak (QP) data, or just Avg and
Peak. When do peak readings trigger the need to report QP? I'm
pretty sure Part 15 has AVG and QP limits listed.
Next was what sort of margin is expected in order to pass CE emissions
requirements (CISPR 16 or 32)? Memory serves that one wants 3dB of
margin, but memories can be imperfect!
