If necessary to achieve the immunity test level, the distance between the transmitting
antenna and the FO3001 may be reduced to 1m. The 1m test distance is permitted by IEC
61000-4-3.
d
For some services, only the uplink frequencies are included.
e
The carrier shall be modulated using a 50 % duty cycle square wave signal.
f
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.
