Sam 271 - Recommended RF Separation Distances

32 Product Support 1-888-202-9831
Guidance and Manufacturer’s Declaration – Immunity
The sam is intended for use in the electromagnetic environment
specified below. The customer or user of the sam should ensure
that it is used in such an environment.
Immunity Test IEC 60601 Compliance Electromagnetic
Test Level Level Environment - Guidance
Portable and mobile communications
equipment should be separated from
the sam by no less than the distances
calculated/listed below:
Conducted RF 3 Vrms (V1) = 3 Vrms D = (3.5V1)(Sqrt P)
IEC 6100046 150 kHz to 150 kHz to 80 MHz
80 MHz
Radiated RF 3V/m D = (3.5Eq)(Sqrt P)
IEC 6100043 80 MHz to (E1) = 3 V/m 80 to 800 MHz
2.5 GHz
D=7E1)(Sqet P)
800 MHz to 2.5 GHz
Where P is the max power in watts and D
is the recommended separation distance
in meters.
Field strength from fixed transmitters,
as determined by an electromagnetic
site survey, should be less than the
compliance levels (V1 and E1).
Interference may occur in the vicinity of
equipment containing a transmitter.
