Recommended Separation Distances Between Portable And Mobile Rf Communications Equipment And The Sonopuls 190 - Enraf Nonius Sonopuls 190 Mode D'emploi

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 Sonopuls 190 is used exceeds the applicable RF compliance level above, the
Sonopuls 190 should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the Sonopuls 190.
B Over the frequency range 15 kHz to 8 MHz, field strengths should be less than 3 V / m.
Recommended separation distances between portable and mobile RF communications equipment
and the Sonopuls 190
The Sonopuls 190 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Sonopuls 190 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Sonopuls 190 as recommended below, according to
the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) can be estimated using the equation applicable to the frequency of the
transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
