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.
