3.0 ImportantSafetyPrecautions
TheCDNmustbesecurelyfastenedtotheearthgroundbeforemakinganyconnectionsto
externalpower.PropergroundingoftheCDNisrequiredinordertopreventhighleakage
currentsfrompresentingapotentialsafetyhazardfortestpersonnel.Tohelpestablish
propergrounding,thebottomsurfaceoftheCDNisunpainted.Inaddition,thebottomplate
hasmountingholesforsecurelyboltingtheCDNtoagroundplane.Ifpropergroundinghas
beenachieved,theresistancemeasuredbetweentheCDNbottomplateandtheground
planeshouldbelessthan10milliohms.

DonotconnectthepowertotheCDNsuntilallthetestequipmentandEUTareinplaceand
electricallyconnected.Avoidhavinganyexposedlivewiresorconnections.Youcanusethe
followingprocedure.

1. ConnectEUTcabletoCDNEUTport.
2. ConnecttheTestGenerator(signalgenerator,poweramplifier,attenuators,etc)to
theRFportoftheCDN.Thetestgeneratoroutputmustremaindisableduntilall
connectionsaremade.
3. Connectaccessoryequipment(AE)port.
3.1MaximumRFinput
DonotexceedRFinputleveltotheCDN.ExcessiveRFinputwilldamagetheCDNinputand
willnotbecoveredunderwarranty.Toavoidaccidentaldamagetothepoweramplifieror
CDN,disabletheRFoutputofpoweramplifierbeforemakinganyconnections.Alsomake
surethesignalgeneratoroutputissettoitsminimumlevelwhentheRFisturnedon.

6.2TestLevelCalibration

BeforeyoubegintestingwiththeCDNyouwillneedtoestablishacalibrateddrivelevels
correspondingtoyourdesiredtestlevels.DuringdrivelevelcalibrationtheRFsignallevel
beinginjectedtotheCDNisadjustedincrementallyuntilthevoltagelevelmeasuredatthe
150Ω to50Ω adapterconnectedtotheEUTportisapproximatelyequaltotheUmr(150)
valuegivenintable1,andthessignalgeneratoroutput,orforwardpowerdeliveredtothe

stepsizesnogreaterthan1%oftheprecedingfrequencyvalueupto80or230MHz.This
equatesto633discretetestfrequencypointsupto80MHzand739pointsupto230MHz.
