Re: [10GBASE-T] RE: EMI Discussion

I agree ... we should reference CISPR Class A only.

Take care

Terry, That isn't quite correct as CISPR should also have a class specified. It would probably be good enough to say CISPR Class A without FCC. There is a part of the range where CISPR is 1 dB looser than FCC, but given the variability in measurement results, that isn't a very significant difference. Other than that, CISPR is the more restrictive of the two.

The correct reference should be:

"Meet or exceed FCC Class A/CISPR or better operation."

This is how we stated in 1000Base-T as an objective. It depends on the country.

If CX4 referenced FCC instead of CISPR then that is something that should
get fixed during sponsor Ballot. The FCC reference is not proper for
something that is on track to be approved at ISO, as we assume that all of
our amendments are.
