No, IEC/EN 61000-6-1 doesn't include it either. There was a BIG argument between experts over the test signal to be used for assessing immunity to mobile phone emissions. CENELEC people prematurely chose the keyed-carrier signal, but it presents inconvenience in both generation and measurement. IEC experts (some from Europe) showed that sinusoidal modulation is quite acceptable and does not present those problems. See Annex A of IEC/EN61000-4-3:1995/7. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
