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.
