NOTE: If necessary, to achieve the TEST LEVEL OF IMMUNITY, the distance between the transmitting antenna and the ME-DEVICE or ME-SYSTEM can be reduced to 1 m.
A test distance of 1 m is permitted in accordance with IEC 61000-4-3.
a) For some radio services, only the radio frequencies for the mobile communications device with the 8en: uplink base station are included in the table.
b) The carrier frequency should be modulated with a square wave signal with a duty cycle of 50%.
c) As an alternative to frequency modulation (FM), pulse modulation with a duty cycle of 50% from 18 Hz can be used, since this, although it is also not an actual
modulation, still represents the worst case.
