I consider that to be correct; the antenna is EUT 2. > >If this all sounds correct, then this is just a sanity check.

I think what you may have missed is that the IEC61000-4-5 surge test may not be appropriate for application to an antenna port. I would look at some ETSI immunity standards to see what tests are applied to antenna ports. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero. ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
