NOTE
If necessary, to achieve the interference immunity test level the distance between the
transmitter antenna and the ME device or ME system can be reduced to 1 m. The 1 m test
distance is permitted under IEC 61000-4-3.
a
For some radio services, only the frequencies for the radio connection from the
communication device to the base unit (en: uplink) were included in the table.
b
The carrier must be modulated with a square wave signal with 50% duty cycle.
c
As an alternative to frequency modulation (FM), pulse modulation with 50% duty cycle
with 18Hz can be used, since this, although not the actual modulation, would nevertheless
represent the worst-case scenario.
