1.1.2 Accurate Time Measurement (Voyager, Advisor T3)
Theinternalcounter/timercircuitryenablesreliable,accurate(2 nsresolution)
time stampingofrecordedbustraffic.Tracesandmeasurementandanalysisfunctions
displaythistiminginformation.Timefieldsaretimestamps,idletimes,bittimes,ortime
deltas,ineitherdecimalorhexadecimalformat.Youcanaddanynumberofmarkersto
denotespecificpackets,youcanmakefurthertimingmeasurementsfromonemarkerto
anotherorfrommarkertotrigger.
AnessentialfeatureoftimemanagementisthatidletrafficdoesnotconsumeAnalyzer
memory.Becauseofthisuniquetechnology,thesystemcanmakeaccuratetiming
calculationswhilestillpreservingvaluablerecordingmemoryforimportantbustraffic.
Theoscillatorhas2.5 ppmaccuracy.
1.1.3 CrossSync Control Panel (Voyager, Advisor T3)
TheCrossSyncControlPanelallowsyoutoselectanalyzersforsynchronizationand
managetherecordingprocess.ItsupportsawidecombinationofTeledyneLeCroy’s
flagshipanalyzersincludingPCIExpress,USB,DDR,SerialATA(SATA),SerialAttachedSCSI
(SAS),FibreChannel(FC)andEthernet.
CrossSyncisTeledyneLeCroy’sanalyzersynchronizationsolutionthatenablestime‐

1.1.4 Comprehensive Error Detection and Analysis
Thesystemdetects,andalertsyouto,everypotentialbuserrorandprotocolviolation,
andtheircombinations.TheAnalyzerBusEngine™circuitryperformsreal‐timetriggering
onmultipleerrorconditions,suchasPIDbad,bitstuffingbad,headerordataCRCbad,
end‐of‐packetbad,babble,activityloss,framelengthviolation,time‐outorturn‐around
