Note: If necessary to achieve the IMMUNITY TEST LEVEL, the distance between the transmitting
antenna and the ME EQUIPMENT or ME SYSTEM maybe reduce to 1m. The 1 m 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 FM modulation, 50% pulse modulation at 18 Hz may be used because while it
does not represent actual modulation, it would be worst case
A3.4 Recommended Separation Distances
Recommended separation distances between
portable and mobile RF communications equipment and the
PA Biofeedback and Stimulation System
The PA Biofeedback and Stimulation System is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the Biofeedback and
Stimulation System can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the PA Biofeedback
and Stimulation System as recommended below, according to the maximum output power of the
communications equipment.
