Conducted RF
EN/IEC 61000-4-6
Radiated RF
EN/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 Model 4701 is used exceeds the applicable RF
compliance level above, the Model 4701 should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the Model 4701.
b
Over the frequency range 150 kHz to 80 MHz, field strengths are less than 3 V/m.

Portable and mobile RF
communications equipment should
be used no closer to any part of the
Model 4701, including cables, than
the recommended separation
distance calculated from the
equation appropriate for the
3 Vrms
frequency of the transmitter.
Recommended separation distance

D=(2.3) (√P)
800 MHz to 2.5 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,
be less than the compliance level in
each frequency range.
