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.
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.
The MANUFACTURER should consider reducing the minimum separation distance, based on RISK MANAGEMENT, and using
higher IMMUNITY TEST LEVELS that are appropriate for the reduced minimum separation distance. Minimum separation
distances for higher IMMUNITY TEST LEVELS shall be calculated using the following equation:
Where P is the maximum power in W, d is the minimum separation distance in m, and E is the IMMUNITY TEST LEVEL in V/m.
