NOTE: If necessary to achieve the IMMUNITY TEST LEVEL, the distance between the transmitting antenna and
the EMS 20 may be reduced to 1m. The 1m test distance is permitted by IEC 61000-4-3.
a
For some services, only the uplink frequencies are included.
b
The carrier shall be modulated using a 50% duty cycle square wave signal.
c
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.
