electromagnetic immunity – for equipment and systems that are not life supporting
Immunity Test Compliance Level
Electromagnetic environment – guidance
Conducted RF
(IEC 61000-4-6)
3 Vrms
150 KHz to 80 MHz
6 Vrms ISM bands
a
Portable and mobile RF communications equipment
should be used no closer to any part of the RNS
®
System, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
b, c
Radiated RF
(IEC 61000-4-3)
3, 10, 20 V/m
80 MHz to 2.7 GHz
e
d = 1.17√P
(80 MHz to 800MHz)
d = 2.33√P
(800 MHz to 2.7 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
d
, should
be less than the compliance level in each frequency
range.
Interference may occur in the vicinity of equipment
marked with the following symbol:
a
Conducted immunity of the Wand (model W-02) compliant to 6 V/m in the ISM bands.
b
Separation distance relevant to Programmer (model PGM-300) and Remote Monitor (model DTR-
300). At 80 MHz and 800 MHz, the higher frequency range applies.
c
These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
d
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 transmitter, an electromagnetic site survey should be considered. If the measured
field strength in the location in which the RNS
®
System is used exceeds the applicable RF
compliance level above, the RNS
®
System should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orienting
or relocating the RNS
®
System.
e
Radiated immunity of the Programmer (model PGM-300), Remote Monitor (model DTR-300-E)
compliant to 3 V/m up to 2.5 GHz. Wand (model W-02) compliant to 10 V/m to 2.7 GHz and spot
frequencies with pulse modulation and to 20 V/m in the communication passband. Spot
frequencies tested are 385 MHz, 450 MHz, 710 MHz, 745 MHz, 780 MHz, 810 MHz, 870 MHz,
930 MHz, 1.720 GHz, 1.845 GHz, 1.970 GHz, 2.450 GHz, 5.240 GHz, 5.500 GHz, 5.785 GHz.
