Recommended separation distances between portable and mobile RF communications equipment
and the SDP1000
The SDP1000 is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled.
The customer or the user of the SDP1000 can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the
SDP1000 as recommended below, according to the maximum output power of the communications
equipment.

For transmitters rated a maximum output power not listed above, the recommended separation distance
d
in
meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where
P
is the
maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1:
At 80 MHz and 800 MHz, the separation distance for 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.
