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.
a ) For some services, only the uplink 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.
