NOTE: If necessary to achieve the immunity test level, the distance between the transmitting antenna and the EM device or EM
system can be reduced to 1 m. According to IEC 61000-4-3, a distance of 1 m is permitted.
a) For some services, only uplink frequencies are included.
b) The carrier wave must be modulated using a rectangular signal fi ll factor of 50%.
c) As an alternative to FM, 50% pulse modulation at 18 Hz can be used, because even if it does not represent real
modulation, it would be the worst case.
