Electromagnetic Immunity
Note 1:
At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2:
These specifications may not be applicable in all situations.
E lectromagnetic propagation is affected by absorption and reflection from structures, objects and persons.
(a): The electromagnetic field strength of fixed radiofrequency emitters, such as base stations for mobile telephones
(cellular / cordless), mobile radio, AM/FM radio broadcasts and TV broadcasts cannot be d
etermined exactly by theory.
To assess the electromagnetic environment due to fixed radiofrequency emitters, an electromagnetic environment
measurement must be made. If the measured radiofrequency field strength in the immediate environment
where the product is used exceeds the compliance level specified above, the performance of the product must be
tested to verify whether it conforms to the specification. If abnormal performance is observed, additional measures
may be necessary, such as reorienting or relocating the product.
(b): In the 150 kHz to 80 MHz frequency range, the electromagnetic field strengths must be less than 3V/m.

Electromagnetic environment – guidance
The X-CUBE i is intended for use in the electromagnetic environment specified below.
The customer or the user of the X-CUBE i should assure that is used in such an environment.
Portable and mobile RF communications equipment
should be used no closer to any part of the X-CUBE i
including cables, than the recommended separation
distance calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
d = 1.2 √P
d = 1.2 √P 80MHz to 800MHz
d = 2.3 √P 800MHz to 2.7GHz
Where ‘P’ is the maximum output power rating of
the transmitter in watt (W) according to the transmitter
manufacturer ‘d’ is the recommended separation
distance (m).
The electromagnetic field strength of fixed radiofrequency
emitters, which is determined by an electromagnetic
environment measurement (a), must be less than the
compliance level in each frequency range (b).

Note 2:
These specifications may not be applicable in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and persons.
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.

Electromagnetic environment – guidance
The X-CUBE i is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the X-CUBE i can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the X-CUBE i as
recommended below, according to the maximum output power of the communications equipment
