If necessary to achieve the immunity test level, the distance between the transmitting antenna and the Medical
Electrical Equipment or 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 50 % duty cycle square wave signal.
c)
As an alternative to FM modulation, 50 % pulse modulation at 18 Hz may be used because while it does not represent actual
modulation, it would be worst case.
