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.
For some services, only the uplink frequencies are included.
a)
The carrier shall be modulated using a 50 % duty cycle square wave signal.
b)
As an alternative to FM modulation, 50 % pulse modulation at 18 Hz may be used because while it does
c)
not represent actual modulation, it would be the worst case.
