EMC Information

Guidance and manufacturer’s declaration - electromagnetic immunity
Portable and mobile RF
communications equipment
should be used no closer to
any part of the
Altrix
system, including cables,
than the recommended
separation distance
calculated from the
equation appropriate for
the frequency of the
transmitter.
Recommended separation
distance
D=(0.35) (√
P
)
80 MHz to 800 MHz
D=(0.70) (√
P
)
800 MHz to 2.5 GHz
where
P
is the maximum
output power rating of the
transmitter in watts (W)
according to the transmitter
manufacturer and
d
is the
recommended separation
distance in meters (m).
Field strengths from fixed
RF transmitters, as
determined by an
electromagnetic site survey
should be less than the
compliance level in each
frequency range.
b
Interference may occur in
the vicinity of equipment
marked with the following
symbol:
Conducted RF
IEC 61000-4-6
3 Vrms
150 kHz to 80 MHz
3 Vrms
Radiated RF
IEC 61000-4-3
10 V/m
80 MHz to 2.5 GHz
10 V/m
Note 1:
At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2:
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
