The information you need is in CISPR 16-1:1999, Tables 1 and 2, clause 4.1.4 and Annex A, and Figure 1. There is far too much to be copied to you. You need either to buy the standard (from http://www.iec.ch) or the DIN equivalent, or find it in a library. -- 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.
