a. For some services, only the up-link frequencies are included.
b. The carrier shall be modulated using a 50% duty cycle square wave signal.
c. As an alternative to FM modulation, 50% pulse modulation at 18 Hz may be used because while it does not represent actual
modulation, it would be worst case.
Note If necessary to achieve the Immunity Test Level, the distance between the
transmitting antenna and the ME Equipment or ME System may be reduced
to 1 m. The 1 m test distance is permitted by IEC 61000-4-3.
