Note:
To reach the INTERFERENCE TEST LEVEL, the distance
between the transmitter antenna and the ME UNIT or ME SYSTEM
can be reduced to 1 m, if necessary. A testing distance of 1 m is
permitted according to IEC 61000-4-3.
a)
For some services, only the uplink frequencies are included.
b)
The carrier should be modulated with a square wave signal with
a duty cycle of 50%.
c)
Alternatively to frequency modulation, a 50% pulse modulation at
18 Hz can be used. As this does not correspond to the current
modulation, this would be the worst case.
