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). 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 represent actual modulation, it would be worst case.
