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 1m. The 1 m test distance is permitted by IEC
61000-4-3.
For some services, only uplink frequencies are included.
a)
The carrier shall be modulated using a 50% duty cycle square wave signal.
b)
As an alternative to FM modulation, 50% pulse modulation at 18 Hz may be used because while it does not repre-
c)
sent 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 should be calculated using the following
equation:
Where P is the maximum power in W, d is the minimum distance in m, and E is the immunity test level in
V/m.
If the ME EQUIPMENT or ME SYSTEM complies with higher immunity test levels or this test, the 30
cm minimum separation distance in 5.2.1.1 f) may be replaced with minimum separation distances calcu-
lated from the higher immunity test levels.
