NOTE: lf 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 SO% duty cycle square wave signal.
As an alternative to FM modulation, SO% pulse modulation at 18 Hz may be used because while it does not represent actual modulation, it would be the worst case.
