Guidance and manufacturer's declaration – electromagnetic immunity
The A&D unit is intended for use in the electromagnetic environment specified below. The
customer or the user of the A&D unit should assure that it is used in such an environment.
Immunity
test
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
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 strengths 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 A&D unit is used exceeds the applicable RF compliance
level above, the A&D unit should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-
orienting or relocating the A&D unit.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

guidance
Portable and mobile RF
communications equipment should
be used no closer to any part of
the A&D unit, including cables,
than the recommended separation
distance calculated from the
equation applicable to the
frequency of the transmitter.
Recommended separation distance:
d = 1.2
3 V
rms
d = 1.2
3 V/m
d = 2.3
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 metres (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.
