Note:Acquisitionmaybe stoppedor in processonthe Remote priortoconnecting.

Connecting/DisconnectingOscilloscopes

Toconnect the oscilloscopes,youmust supply:

l 2 standardBNCcables l 1 standardEthernet cablefor a direct connection,or 2 Ethernet cablesto connect each machinetoa

networkaccesspoint

1. Connect one BNCcablefrom RemoteRefOutto MainRefIn.

2. Connect theother BNCcablefrom Remote AuxOut to MainAuxOut.

3. Connect theEthernet cablefrom RemoteENET to MainENET,or connect each of the oscilloscopesto yournetworkindividually.

Note:Theonlyrequirement isthat both machinesare on thesame network,andthat the

Remote and Mainare accessibletoeach other.

Deskewing

Althoughtheintrachannelskewof the oscilloscopesisnegligible,youmay optionally deskewinputsto account for propagation delayscausedby cablesbetweeninstruments,etc. To do this,we recommend:

1. With theoscilloscopessynchronized,usea splitter to input one half of arepetitivesignal(e.g.,sine orsquarewave) toanyof channelsC1-C8 and theother half toanyof channelsC9-C16.

Tip:Ideally,onechannelshouldbe thetriggerchannel,andthe second anychannelfrom theother oscilloscope.

2. Turn on bothchannels.Adjust the timebasesothat thefalling edgeof thepulses isclearlyvisible.

3. OntheOscilloSYNCSetup dialog,enteraTriggerSkewCorrectionvalueineither Remote (C9-C16) orLocal(C1-C8),depending onwhich bankcontainsthe triggerchannel,sothat the fallingedgeof theRemote oscilloscopepulsealignswith the fallingedgeof the Mainoscilloscopepulse.

Maximum Memory.It changesto show SamplingRate,thenumber of samplestakenpertime division, whenusingaFixedSamplingRate.

Set Maximum Memory,the default settingon MAUI oscilloscopes,automaticallyadjusts the samplingrate totake themaximum numberof samplespossible giventhe amount of pre-or post-triggerDelayandthe Time/div,up to themaximum record length. Thisoptimizesthe sample rate for fast timebaseswhenin RealTime mode.

FixedSamplingRateactivates theSamplingRatefieldfor youto set your ownrate.Theoscilloscopewill usewhateverMemoryasrequiredfortheacquisitiontime,until noneremains.Loweringtherate can extendtheacquisitionto accommodate slower timebasesor longerdelays.

Note:To avoidaliasing andotherwaveform distortions,it isadvisable(perNyquist) toacquireat a samplerate at least twice the bandwidth of the input signal.Asamplerate 10 times the acquisitionbandwidthmay bepreferableinorderto over samplefast signalrisetimesconsistent withtheoscilloscopebandwidth.Thosewith higherspeedacquisitionsystemsmay needto manuallyadjust Bandwidth,Time/div,SampleRate,and thenumber of ActiveChannelsto achieve theoptimalresult.

On WaveRunner/MDA8000HD,if you set aFixed SampleRate of 10 GS/s,the system automatically enters EnhancedSampleRate,applying 2 pts.Sinx/x interpolationto prevent aliasing. The codeE/ESRwill appearon thedescriptor boxesof the activechannels.Youcanmanuallyapply5 pts.Sinx/xInterpolation toanychannelonthe Cn dialog.

Active Channels

When operatingat the fullchannelcount,allchannelsremainactivefor input at thestandardper channel specification.To achievethe maximum possiblememory,choosea reduced channelcount under Active Channelson the Timebasedialog,or chooseAutomode(Maximize).Thiswillinterleavethe acquisition capabilitiesof different pairsof channelsto increaseperformance.

ReducedChannelModes

Reducingchannelsturnsoff onechannelineach pairof adjacent channels,leavingtheother available at twice the standardmemory.Generally,within each bankof four channels,the "inner"two channelsareleft active,whilethe"outer"channelsare turnedoff. C1can stillbe usedfor triggerinput (e.g.,inPattern triggers),but not for waveform acquisition.

Example:On WaveRunner8000HD,selecting 4 ActiveChannelsturnsoff acquisitionon C1,C4,C5 andC8,whileC2,C3,C6 and C7 acquireat double the perchannelacquisitionmemory.

On 8-channeloscilloscopeswith twobanksof four channels(C1-C4 and C5-C8),a similar interleavingof outer and innerpairsoccurswhen2ActiveChannelsis selected,leavingC3 andC6 activeat the maximum possiblememory.

AutoMode(Maximize)

InAuto mode,theoscilloscopewillallot the maximum memory possible basedon the activity withineach pairof channels. Aslong asonlyonechannelineach of thepairsisturned on,regardless of which number, themaximum memoryfor the totalnumber of activechannelsisused.Turningon bothchannelsinany pairhasthesameeffect asselectingthefullnumberof ActiveChannels,and each channelwillacquireat thestandardspecification.

Likewise,for 8-channeloscilloscopes,turningona channelfrom bothpairsineither bankwilldrop the memoryandsamplerate to that of 4ActiveChannels,evenif only two channelstotalare turnedon.

Example:WhenAuto isselected on WaveRunner8000HD,C1,C3,C5 andC7can alloperate at twice the per channelmemory,theequivalent of4ActiveChannels. Howeveracombinationof C1, C2,C5 andC7woulddropthe per channelmemory tothesameas8 activechannels,as woulda combinationof C1,C3,C7 andC8.Becauseboth channels in a single pair are active,it is thesame asselecting8 ActiveChannels. C1 and C3 canonlyoperate together at twice the perchannel memory,becauseboth arewithinthe same bank,but C1 and C6 couldoperateat maximum memory,astheyarenot onlyin different pairsbut in different banks.

Refer toAcquisitionSystem intheproduct datasheet for maximum memoryin each mode.

Sampling Modes

TheSamplingMode determineshow theinstrument samplestheinput signalandrendersit for display.

RealTimeSamplingMode

RealTime samplingmodeisa seriesof digitizedvoltagevaluessampledonthe input signalat auniform rate. Thesesamplesare displayedasaseriesof measureddata valuesassociatedwithasingle trigger event.Bydefault (with no Delay),the waveform is positionedso that thetriggerevent is time 0 onthe grid. Therelationship between sample rate,memory,andtimecan be expressed as:

CaptureInterval =1/(SampleRateX Memory)

CaptureInterval/10=TimePer Division

Usually,on fast timebasesettings,themaximum samplerate isusedwhen inReal Timemode.Forslower timebasesettings,thesamplerate isdecreasedso that the maximum number of data samplesis maintainedovertime.

RollSamplingMode

Theacquisitionis completewhenatriggerevent is detected,at which point the next acquisitionbeginsimmediately.Parametersor math functionsare updatedeverytime the rollmode bufferisupdated asnew databecomes available. Thisresetsstatistics oneverystep of Rollmode that isvalidbecauseof newdata.

Timebasemust beset sufficiently slowtoenable Rollmodeselection;increaseTime/divto 100 ms/divor more and increasesamplerate to 5 MS/sorlesstoactivate the Rollmodeoptionon the Timebasedialog. OnlyEdge triggerissupported for Rollmode acquisitions.

Note:Rollmodesamplingisnot availablewhenusinganotherform of digitalinterleaving.If processingtime isgreater than acquisitiontime,therollmodebuffer isoverwritten. The instrument warns,"Channeldata isnot continuousinROLL mode!!!"and rollingstartsagain.

SequenceSamplingMode

InSequenceMode sampling,the completedwaveform consists of anumberof fixed-sizesegments. The instrument usesthe TimebaseSequencesettingsto determinethe capture durationof eachsegment. Thedesirednumber of segments,maximum segment length,andtotal available memory are usedto determinethe actualnumberof samplesor segments,and time or points.

Trigger

Triggersdefinethe event aroundwhich digitizedinformation isdisplayed on the grid. Different Trigger Typesare usedto select different events inthetriggersource waveforms:edgevoltages,

Trigger Set Up

ToopentheTriggerdialog,pressthe front panelTriggerSetupbutton or touch the Triggerdescriptor box. Different controlswillappeardependingontheTriggerTypeselected (e.g.,Slopefor Edgetriggers).

Completethesettingsshownafter making your selection. Thetriggerconditionis summarizedin apreviewwindowat the far right oftheTriggerdialog.Refer to this

toconfirm your selectionsare producingthetrigger youwant.

Source

For most triggers,the Source isthe analogchannelor digitallineto inspect for the triggerconditions. Pattern triggersmay utilize multiplesources(such asa mixof analoganddigital signals),and likewise MultiStagetriggersmay usedifferent sourcesfor the armingand triggeringevents.

Tip:On instruments with OneTouch,thetrigger source canbe easilyset by draggingthedesired channeldescriptor boxonto theTriggerdescriptor box.Notethat the triggercouplingand slope/polarity willrevert towhateverwaslast set onthat channel.

Coupling

For analogtriggers,specify thetypeof signalCouplingat theinput:

l DC-Frequencycomponents arecoupledto the triggercircuit for highfrequencybursts,or wherethe

useof ACcouplingwouldshift the effectivetriggerlevel.

l AC-Capacitivelycoupled.DClevelsare rejected,andfrequenciesbelow50 Hzareattenuated. l LFREJ-Coupledthrougha capacitivehigh-passfilternetwork,DCisrejectedandsignalfrequencies

below50 kHz are attenuated.Forstabletriggering on medium to highfrequency signals.

l HFREJ -DCcoupledto the triggercircuit,and a low-pass filter network attenuatesfrequenciesabove

50 kHz(usedfortriggering on low frequencies).

Slope/Polarity

For sometriggers,such asEdge,youwillbe askedto select thewaveform Slope(risingvs.falling) on which thetriggeringevent mayoccur. Forothers,such asWidth,theequivalent selectionwillbePolarity(positive vs.negative).

WaveRunner/MDA8000HDOscilloscopes Operator's Manual

Level

For analogtriggers,enter the voltageLevelat whichthetriggeringcondition must occur. Usethe Find Levelbuttonto set theleveltothe signalmean.

Triggertypesthat requiremultiplecrossingsto definethe triggeringcondition—suchasWindow,SlewRate andRunt—willhaveUpperLeveland LowerLevelfields.

For digitalpatterntriggers,thelevelis determinedbythe LogicFamilythat is set on the digitalgroup.This can alsobe specifiedby acustom (User-Defined)crossingThresholdand Hysteresis. Usually,therewillbe aseparateLogic tab for thesesettings.

Hysteresis

For Edgetriggers,youmayselect to OptimizeforHF.When thisboxisunchecked,thetrigger circuit's hysteresisisset quite highto eliminateanypotential triggerinstability from high-frequency noiseridingon alow-frequencyinput signal.BecauseHFsignal amplitudestend to besmaller,the Optimizefor HFsetting reducesthe hysteresisvalueto makethe triggermore sensitive.The effect thiswillhaveontrigger behavior dependson thesignal'sspectralandnoisecontent rather than just fundamentalfrequency,soit's overall effect is difficult toquantify.

Conditions(SmartTriggers)

Smart triggersallallow youto applyBooleanlogictorefine thetriggering conditionbeyondsimplyLevel andSlope/Polarity.

Thevaluesthat satisfythe operatorsof LessThan,LessThanorEqualTo,GreaterThan,etc. canbeset by enteringanUpperValueand/or LowerValue.

Insomecases,it ispossible to set a range of valuesthat satisfy thecondition. Dependingonthetrigger, thevaluesmaybe InRangethat isboundedbythe upper/lowervalues,or Out Range.

Theextent of therangecanoften alsobe specifiedby usinga NominalandDelta value,rather thanan absolute upperandlower value.In thiscase,the Nominalvaluesetsthecenter of therange,andtheDelta determineshow manyunitsplus/minustheNominalvalueareincludedin therange.

Measure

Parametersaretoolsthat giveyouaccessto a widerange of waveform properties,such as Rise Time, RMSvoltage andPeak-Peakvoltage.The instrument offersa quick selectionof standardparameters,or youcancreate auser-definedset of parameters(MyMeasure)drawnfrom all availablemeasurements.

On instruments equippedwith CustomDSO(XDEV),custom scripts maybe usedto calculateaparameter. Severalscripting"languages"are supported,depending on theapplication.Youcanfindtheseoptionsin theCustom submenuof the MeasureSelector. Scriptsmay be imported or written inthe instrument's Script Editorwindow. SeeUsingPScript for a descriptionof the process.

Parameter readouts are shownina dynamic Measuretablethat appears below thewaveform grids. All activemeasurementscan beusedasinputsto other processes,such asPass/Fail tests,evenwhenthe Measuretableishiddenfrom view.

Statistics and Histicons

CheckingStatisticsOnon the Measuredialogaddsthe mean,min,max andsdevof each parameter to the measuredvalueshownon theMeasuretable.

Statistics for each parameterarecalculatedonce peracquisitionandaccumulate untilyoueither Clear Sweepsor themeasurement buffer isfull.TheNum rowof the Measuretableshows thetotal numberof measurementsincludedin theStatistics calculation.If themeasurement isgated,the statisticsare calculatedforonlythedata points betweenthegates,just asthe parameter valueitself willreflect the limitsimposedbythegate.

Mean Theweightedmeanof the parameter calculatedover thenumber of times shown. Min Theminimum value of the parameter measuredover the number of times shown. Max Themaximum valueof theparameter measuredover thenumber of times shown. Sdev Thepopulation standard deviationof theparameter calculated over thenumber of times

shown.

Num For anyparameter that computes onceonan entireacquisition,Num represents thenumber

of sweepsover whichthestatistics arecomputed.

For anyparameter that computes onevery eventwithinanacquisition,such as afullperiod, Num represents thenumber of events per sweeptimes thenumber of sweeps computed. Thus,for aSingleacquisition of five periods,theNum shown for any perperiodmeasurements will be5,as fivemeasurements were madeandthe statistics reflect thosefive measurements.After anotherSingleacquisition,Num will be 10,or five measurements times twosweeps.The statistics now reflect all 10 measurements.

Histiconsare miniaturehistograms of parameters that maybe addedto theMeasuretablereadout. Thesethumbnailhistograms let you seeat a

Measure

Gating Measurements

All measurementsare calculatedon onlythat portionof thewaveform tracethat is visible onthegrid and withinthe measurement gates.On >500 Mptsacquisitions,measurements are alsolimitedtothecenter 500 Mpts of theacquisition.Anysettingthat movesthetrace outsidetheobservation window or makesit appear"clipped"willaffect measurements.

Thedefault startingpositionsof themeasurement gate posts are0 div and10 div,which coincidewiththe left andright edgesof thegrid,and theFirst andLast points. Therefore,the measurement gates initially enclosethe entire visible acquisition.Bymovingthemeasurement gates,you canfocusthe measurement onthe sectionof theacquisitionof greatest interest.For example,if you"gate"sixrisingedgesof a waveform,calculationsareperformedonlyonthesixpulsesboundedby thegate posts.

Gates (vertical whitelines)limit thedata measured andvisiblychangemeasurement calculations.

Thequickestwaytoset a gateisto dragthegate posts from thefarleft andright of thegridto the desired positions. Youcan refinethissettingto hundredthsof adivision byusingtheGate Start and Stopfields on theMeasuredialogfor Standardparameter sets,or on the Gate subdialog for user-defined parameters.TouchDefault to returnthemeasuregatestothe width of the grid.
