NOTE:
If necessa~ to achieve the IMMUNITY TEST LEVEL, the distance between the transmitting antenna and the ME
EOUIPME Tor 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.
