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.
