The equipment SIRIUS is intended for use in the electromagnetic environment specified below. The
customer or the end user of the SIRIUS should assure that it is used in such an environment
Electromagnetic environment - guidance
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
3Vrms (150KHz
to 80MHz)
10 V/m
80 MHz to 2.7
GHz
Portable and mobile RF communication equipment
should be used no closer to any part of the SIRIUS,
including cables, than the recommended separation
distance calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance.
d=1,167*sqrt (P)
d=1,167*sqrt (P) 80 MHz to 800 MHz
d=2,333*sqrt(P) 800 MHz to 2,7 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
a
,
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:
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.
a) Field strength from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field strength in the location in which the SIRIUS is used exceeds
the applicable RF compliance level above, the SIRIUS should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating
the SIRIUS
b) Over the frequency range 80MHz to 2.7 GHz, field strength should be less than 10 V/m.
