2.2.6 EMI Consideration
Various interference sources,from eitheroutsideorinside the device or applicationsystem,affectthe system inthe
conductive ways such as capacitive coupling,inductivecoupling,andelectromagneticradiation.Thereare two types of
electromagneticinterferences:radiated interference and conducted interference,dependingon the type of the
propagationpath.Whenthe energy, often RF energy, from a componentarrives ata sensitivecomponentvia the space,
the energyis knownas radiatedinterference.The interferencesourcecan be either a part of the interferedsystem or a
completelyelectricallyisolated unit.Conductedinterferenceresults from theelectromagneticwire orsignalcable
connectionbetweenthe source and the sensor,.Interference alongthecable the interference is transmitted from oneunit
to another. Conductedinterferenceoften affects the powersupplyof the device, but can be controlledbya filter.
Radiated interference mayaffect any signal pathin the device, and is difficult to shield.
Effective measuresshould be taken for the powersystem to prevent electricgrid interference.
The working ground of the routers should be properlyseparatedand keptas far as possible from thegrounding
device of the powerdevice or the anti-lightning grounding device.
Keep the device away from high-powerradio transmitter,radartransmitting station,andhigh-frequencylarge-
current device.
Measures mustbe takento isolatestaticelectricity.
2.3 Precautionfor FiberConnection
