Radiated RF EM
Fields
IEC61000-4-3
NOTA 1: U is the a.c. mains voltage prior to the application of the test level
T
NOTA 2: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTA 3: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people
NOTA 4: As bandas ISM (industriais, científicas e médicas) entre 0,15 MHz e 80 MHz utilizam as
frequências 6,765 MHz a 6,795 MHz; 13,553 MHz a 13,567 MHz; 26,957 MHz a 27,283 MHz; e 40,66 MHz
a 40,70 MHz. As bandas de rádio amador entre 0,15 MHz e 80 MHz utilizam as frequências 1,8 MHz a 2,0
MHz, 3,5 MHz a 4,0 MHz, 5,3 MHz a 5,4 MHz, 7 MHz a 7,3 MHz, 10,1 MHz a 10,15 MHz, 14 MHz a 14,2
MHz, 18,07 MHz a 18,17 MHz, 21,0 MHz a 21,4 MHz, 24,89 MHz a 24,99 MHz, 28,0 MHz a 29,7 MHz e 50,0
MHz a 54,0 MHz
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
device is used exceeds the applicable RF compliance level above, the device should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the device.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.

in watts (W) according to the
transmitter manufacturer and d is the
recommended separation distance in
meters (m).b
Field strengths from fixed RF
transmitters, as determined by
an electromagnetic site survey ,a
should be less than the compliance
level in each frequency ranged.
