NOTE If it is necessary to achieve the IMMUNITY TEST LEVEL, the dis-
tance between the transmitting antenna and the ME EQUIPMENT or
ME SYSTEM may be reduced to 1 m. The 1 m test distance is permit-
ted 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 it does not represent actual modulation. It
would be worst case.
