NOTE If necessary to achieve the IMMUNITY TEST LEVEL, the distance between the transmitting antenna and the monitor 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 percent duty cycle square wave signal.
c
As an alternative to FM modulation, 50 percent pulse modulation at 18 Hz may be used because while it does not represent actual
modulation, it would be worst case.
