TheSATA2.5TestAdapterCareandHandlingPrecautions
TheSATA2.5TestAdapterrequirescarefulhandlingtoavoiddamage.Improperhandling
techniques,orusingtoosmallacablebendradius,candamagethecoaxialcableconnections
withintheadapterhousingorthecablesthemselves.Thiscanoccuratanypointalongthe
cable.ToachieveoptimumperformanceandtoprolongtheSATA2.5‐TPA’slife,observethe
followinghandlingprecautions:
CAUTION1:AvoidTorqueForces(Twisting)
Whileindividualcoaxialcableswithinthetestadapterhavesomerotationalfreedom,
twistingtheSATA2.5‐TPAasaunit,withoneendheldstationary,maydamageorseverely
degradeperformance.AdherencetoCaution5(below)helpstoavoidtwisting.

CAUTION2:AvoidSharpCableBends
Neverbendcoaxialcablesintoaradiusof26mm(1‐inch)orless.Neverbendcables
greaterthan90°.Singleormultiplecablebendsmustbekeptwithinthislimit.Bendingthe
SATA2.5‐TPAcableslessthana26mm(1‐Inch)radiuswillpermanentlydamageorseverely
degradetestadapterperformance.

CAUTION3:AvoidCableTension(PullForces)
Neverapplytension(pullforces)toanindividualcoaxialcablethatisgreaterthan2.3kg
(5lbs.).Toavoidapplyingtension,alwaysplaceaccessoriesandequipmentonasurface
thatallowsadjustmenttoeliminatetensionontheSATA2.5‐TPAandcables.Useadjustable
elevationstandsorapparatustoaccuratelyplaceandsupporttheSATA2.5‐TPA.

CAUTION4:ConnecttheSATA2.5‐TPAFirst
Topreventtwisting,bending,orapplyingtensiontothecoaxialcableswhenconnectinga
SATA2.5‐TPA,alwaysattachtheSATA2.5‐TPAtothedeviceundertest(DUT)orcableunder
testbeforeattachinganySMAconnectors.CarefullyaligntheSATAconnectorsandthen
gentlypushtheconnectorstogetheruntilfullyseated.

IftheSATA2.5‐TPAmustbeturnedortwistedtomakeconnectiontotheDUT,avoidusing
theSATA2.5‐TPAhousingalonetomakethisoccur.Trytodistributethetorqueforcesalong
thelengthofthetestsetupandcabling.Ifthisisnotpossible,itisrecommendedtofirst
loosenordisconnecttheSMAconnectionsattheSATA2.5‐TPA,maketheconnectiontothe
DUTandthenre‐tightenorattachthetestequipmentleads.
NOTE:Onlygripthetestadapterhousingwheninsertingor
extractingtheSATA2.5‐TPAtoorfromtheDUT.Pullingdirectlyon
theSATA2.5‐TPAcablesorusingthemtoinserttheSATA2.5‐TPAmay
causedamage.
CAUTION5:CarefullyMakeSMAConnections
ToconnecttheSATA2.5‐TPASMAconnectors,followthesesteps:
1. Holdthecablestationarybygraspingthecableattheblackheat‐shrinksection
neartheSMAconnector.
2. InsertthematingSMAbarrelandhand‐tightenthefree‐spinningSMAnutontothe
connectorwhileavoidingpulling,bending,ortwistingtheSATA2.5‐TPAcoaxial
cable.

3. TheSATA2.5‐TPASMAconnectorshaveflatsthatacceptanopen‐end1/4‐inchor
6.5mmwrench.WhenattachinginstrumentcablestotheSATA2.5‐TPA,itisrecom‐
mendedthattheSATA2.5‐TPASMAconnectorsbemechanicallyheldandthetest
leadsbetightenedtotheequipmentmanufacturer’storquerecommendations,
normally5in‐lbs,usinga5/16‐inchopen‐endwrench.
Ifthetestset‐uprequiresrepositioning,firstloosenordisconnecttheSMAconnectionsto
avoidtwisting,bending,ortension.
NOTE:Adropinsignalamplitudebyhalfor6dbduringthetestingof
achannelmayindicatethatacablehasbeenmechanicallypulled
freeofcoaxialcableconnectionsinternaltotheassembly.Thiscould
bedeterminedbycheckingifthecablehasanylateralplayrelative
totheTPA.ThiswouldonlyoccurwhentheTPAhasexceededthe
pullforceasspecifiedwithinthemechanicalspecification.Ifthe
cablecannotbere‐seated,thetestadapterwillneedtobesentback
tothefactoryforservice.
CAUTION6:IndependentlySupportInstrumentCablesorAccessories
Excessiveweightfrominstrumentcablesand/oraccessoriesconnectedtotheSATA2.5‐TPA
cancausedamageoraffectthetestadapterperformance.Besuretoprovideappropriate
meanstosupportandstabilizealltestset‐upcomponents.

VisualInspection
Besuretoinspectallcablescarefullybeforemakingaconnection.Inspectallcablesfor
metalparticles,scratches,deformedthreads,dents,orbent,broken,ormisalignedcenter
conductors.Donotusedamagedcables.
Cleaning
Ifnecessary,cleantheconnectorsusinglow‐pressure(lessthan60PSI)compressedairor
nitrogenwithaneffectiveoil‐vaporfilterandcondensationtrap.Cleanthecablethreads,if
necessary,usingalint‐freeswaborcleaningclothmoistenedwithisopropylalcohol.Always
completelydryaconnectorbeforeuse.Donotuseabrasivestocleantheconnectors.Re‐
inspectconnectors,makingsurenoparticlesorresidueremains.
MakingConnections
Beforemakinganyconnections,reviewthe“CareandHandlingPrecautions”section.Follow
theseguidelineswhenmakingconnections:
Aligncablescarefully
Makepreliminaryconnectionlightly

ElectrostaticDischargeInformation
Protectionagainstelectrostaticdischarge(ESD)isessentialwhileconnecting,inspecting,or
cleaningtheSATA2.5‐TPAtestadapterandconnectorsattachedtoastatic‐sensitivecircuit
(suchasthosefoundintestsets).
Electrostaticdischargecandamageordestroyelectroniccomponents.Besuretoperformall
workonelectronicassembliesatastatic‐safeworkstation,usingtwotypesofESDprotection:
Conductivetable‐matandwrist‐strapcombination
Conductivefloor‐matandheel‐strapcombination
Whenusedtogether,bothofthesetypesprovideasignificantlevelofESDprotection.Used
alone,thetable‐matandwrist‐strapcombinationprovideadequateESDprotection.Toensure
usersafety,thestatic‐safeaccessoriesmustprovideatleast1MΩofisolationfromground.
AcceptableESDaccessoriesmaybepurchasedfromalocalsupplier.
WARNING:Thesetechniquesforastatic‐safeworkstationshould
notbeusedwhenworkingoncircuitrywithavoltagepotential
greaterthan500volts.

Calibration
TheSATA2.5PlugandReceptacleTestAdaptersarepassivecomponents.Therefore,
calibrationfortheerrorsgeneratedmustoccurwithinthetestinstrumentationthatdrivesthe
SATAreceiverdeviceorlooksattheresponseoftheSATAtransmitterdevice.
TheSATA2.5‐TPA‐C‐2Xcableisusedtoprovide2X‐THRUfunctionality.TheSATA2.5‐TPA‐C‐1X
cableprovides1X‐THRUfunctionalityforcalibration.TheSHORT,OPEN,andLOADfunctionality
isprovidedfromauser‐suppliedcalibrationkit.

SOLT

SHORT,OPEN,LOAD,and2X‐THRU(SOLT)arecalibrationstandardsusedtocompensatefor
errorsassociatedwiththeTPAwhenusedforJittermeasurement,TDR,TDT,andVNAtesting.
SOLTrepresentsthesameelectricallengthandlossesastheTPAthroughtheSATAconnector
pad,andenablesthetestengineertocompensateforthefollowingsixrepeatable,systematic
errorsthatoccurwhenmovingthereferenceplane:
Signalleakageeffects:Directivityerrors
Signalleakageeffects:Crosstalkerrors
Reflectioneffects:SourceImpedanceMismatchingerrors
Reflectioneffects:LoadImpedanceMismatchingerrors
Bandwidtheffects:ReceiverTransmissioninTestEquipmenterrors
Bandwidtheffects:ReceiverReflection‐trackinginTestEquipmenterrors
Theseerrorsneedtobecorrectedoneachport.RefertotheInstrumentManualfor
instructionsontheinstrument’sspecificcalibrationprocess.
NOTE:Thereferenceplaneistheboundary,bothphysicallyand
electrically,betweenthecalibratedanduncalibratedportionsof
thecircuit.Everythingoutsidethereferenceplaneisconsidered
partoftheDUT.Anyinstrumentthatdoesnotusecalibration
definestheDUTasthetotalofexternallyconnectedcomponents.
IftheSATA2.5‐TPA‐C‐1XorC‐2XCalibrationCablesarenotused,all
oftheSATA2.5‐TPAandassociatedcoaxialcables,aswellascables
connectingtheTPAassemblytothetestinstrument,wouldbeapart
oftheDUT.
Non‐repeatableerrors,suchasdriftorrandomerrors,canbereducedbutnotcorrected.
Drifterrorsaggregateovertimeorwithenvironmentalchangessuchastemperatureshift.To
eliminatedrifterrors,performanothercalibration.
Arandomerrorcannotbecorrectedthroughcalibrationsincetheerroroccurredrandomly.
Randomerrorsaretypicallyassociatedwitheithertestinstrumentnoiseortestrepeatability
problems.Reducetestinstrumentnoisebyincreasingsourcepower,loweringtheIF
bandwidth,oraveragingresultsovermultiplesweeps.Reducetestrepeatabilityproblems
throughtheuseofatorquewrenchor,again,byaveragingovermultiplesweeps.

1XTHRU
The1X‐THRUisacalibrationfeatureusedtocalibratetimedomaininstrumentation(for
example,pre‐emphasizedpulsegeneratorsorAWGs,arbitrarywaveformgenerators).1X‐THRU
calibrationcompensatestwoerrorsources–cablelossesandgroupdelay:
CableLosses–CablelossesassociatedwiththeSATA2.5plugTPA,anditsrespectivecabling
that’sconnectedtothetestsource,consistofskinlossand,toalesserextent,dielectricloss.
Pre‐emphasisorde‐emphasisisusedatthesignalsourcetocorrectforthesecablelosses.
Pre‐emphasisisaboostofthesignalleveljustafteranedgetransition;de‐emphasisisa
reductioninthelow‐speedamplitudeofthesignalsource.Typically,onade‐emphasized
signalthelevelshavetoberesettoattainthesameoutputlevels.Resultantsignalsfrom
eitherpre‐emphasisorde‐emphasisareidenticalrelativetotheDUT.

Forthepurposesofthisdiscussion,pre‐emphasiswillbeused.Tosetthepre‐emphasis,first
determinetheamountofsignalboostbyconnectingthesignalsource,viathe1X‐THRUand
therespectivecableusedtoconnecttheDUTtothesourcetoahigh‐speedoscilloscopeora
jittermeasurementdevice.Triggertheoscilloscopeorjittermeasurementdeviceusinga
triggerfromthesource.Thetrigger,asingleevent,indicatesthestartofthesignalbeing
senttotheDUT.Adjustpre‐emphasistomaximizetheeyeopening.

GroupDelay–Groupdelayistheseconderrorsourcefor1X‐THRUcalibration.Whenthe
DUTgeneratesanoutputsignal,itcanbeusedtomeasuredelay.Tocreateabaselinedelay
measurement,connecttheoutputsignalcabletotheinputsignalcableandthe1X‐THRU.To
determinecorrectedDUTdelay,subtractthisbaselinemeasurementfromtheDUTdelay
measurements.
