Recommended Separation Distance - Enraf Nonius Radarmed 950+ Instrucciones De Utilizacion

Guidance and manufacturer's declaration – Electromagnetic immunity
The RADARMED is intended for use in the electromagnetic environment specified below. The
customer or the user of the RADARMED 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 RADARMED is used exceeds the applicable RF compliance level
above, the RADARMED should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the RADARMED.
B Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

3 Vrms Portable and mobile RF
communications equipment should
be used no closer to any part of
the RADARMED, including cables,
3 V/m than the recommended separation
distance calculated from the
equation applicable to the
frequency of the transmitter.
Recommended separation
distance
�� = 1,17 √ ��
�� = 1,17 √ �� (80 ������ ���� 800 ������)
�� = 2,33 √ �� (800 ������ ���� 2,5 ������)
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
should be less than the
compliance level in each
frequency range
