I'd be grateful if anyone could point me in the direction of any thorough reports on RF immunity levels expected by Performance Category type (5e, 6, etc) UTP (unshielded twisted pair) structured cabling. I've seen reference to TIA levels of 3 V/m, and reference to test method IEC 61000-4-3. Not sure on how folk are interpreting the results. Just looking at change of bit error rate? Maybe could look at frequency spectrum on each pair and see if levels are significant enough to degrade S/N.
Thanks in advance,
Bob Elliot
