4.0 ImportantSafetyPrecautions
TheLISNmustbesecurelyfastenedtotheearthgroundbeforemakinganyconnectionsto
externalpower.PropergroundingoftheLISNnotonlyensurescorrectconductedemissions
measurementsandalsopreventspotentialhighleakagecurrentfrompresentingahazardtest
personnel.TohelpestablishpropergroundingthebottomsurfaceoftheLISNisunpainted.In
addition,thebottomplatehasholesforsecurelyboltingtheLISNtothegroundplane.
OnlyconnectEUTswithpowerplugwithaprotectiveearthcontactshouldbeinsertedintoLISN
powerinputport.Theprotectiveactionmustnotbenegatedbytheuseofacheaterplugoran
extensioncordwithoutaprotectiveconductor.

Maintenance
Therearenouserserviceablepartsinsidetheunit.UsermodificationstotheLISNswillvoid

7.0 LISNTheory

7.1Overview

LineImpedanceStabilizationNetworksusedsupplystandardizedlineimpedancetotheEUT
duringconductedemissionstestingwhichisindependentoftheexternalpowerlineimpedance.
ThestandardizedimpedanceenablesconsistentreadingsforRFnoisemeasurementsonthe
powerline.ThemodelLI‐215AconsistsoftwoseparateLISNnetworkshousedinasingle
enclosurefortestingEUTswithsinglephasepowerrequirementsdownto9kHz.

Inadditiontoprovidingstandardizedimpedance,theLISNalsoactsasalowpassfilterforthe
powertoequipmentundertest.TheLISNblocksRFnoisefromthepowerlinefromreachingthe
equipmentundertest,however,thepowertotheequipmentpassesthroughtheLISNwith
minimaleffect.ThisfiltercomprisesoftwostagelowpassLCfilters.Therefore,therearetwo
capacitorsandtwoinductorsforthefilters.ThetwoinductorsusedintheLI‐215Aareaircore
typetoeliminatethepossibilityofsaturationandtoprovidestability.

TheLISNalsoprovidesalowimpedancepathfortheRFnoisefromtheEUTtothemeasuring
equipment,therebyfacilitatingthemeasurementoftheRFnoise.Theinsertionlossofthe
measurednoisemaybesignificantatlowfrequency.Therefore,atfrequenciesbelow400kHz,
theinsertionlosscorrectionfactormustbecompensatedforhighestaccuracynoise
measurement.

TheschematicoftheLISNaswellaslineimpedanceisspecifiedintheANSIC63.4asCISPR‐16‐1‐
2standards.AtypicalcircuitdiagramofanLISNisgiveninFigure1below.
