Second, please folks, there is no such thing as an EMC receiver. It may
seem
like semantics, but you can’t receive electromagnetic compatibility. May be
you can ask Santa for it, but I doubt he will deliver.
True; it's the Easter Bunny that delivers!
What you receive is EMI – electromagnetic interference, and the entire
purpose of the receiver is to quantify the amount of EMI, and compare it to a
limit. The limit is there to control the amount of EMI generated so that we
can expect some level of electromagnetic compatibility.

Again, I have to disagree just a bit. What you receive on your spectrum
analyzer (or EMI Receiver or whatever) is not EMI; it's just some energy at
some point in the spectrum. That energy can only be considered interference if
the undesired response of some equipment is considered. Otherwise, that energy
is not hostile EMI, it's just there.
Your signal is my noise, and my signal is your noise.
