Conducted RF

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 radio, 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 MicroRPM is used
exceeds the applicable RF compliance level above, the MicroRPM should be
observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orientating or relocating
the MicroRPM.
