Interacting with Cursors
Cursorsareeasilyappliedtothewaveformdisplayarea(seeTheCursorsTooltopicformoreinformation).
Tools
ControlsforLogicStudio’sbuiltinToolsarelocatedinthespaceabovetheWaveformDisplayArea.Thebuiltin

The Cursors Tool
ThistopicdemonstratestheuseoftheCursorstool.

WhentheCursortoolisenabled,youarecurrentlyarmedwiththeselectedcursorpaironthewaveform
display.Whenexpanded,thetool’sdetailedcontrolprovidesstorageforupto4cursorpairs.Whencursorsare
placedonthedisplay,theyarehighlightedwhenthepairisselectedfromthenumberedcursorpair.Removea
pairbyclickingtheRemoveCursorbuttonontherightsideofthenumberedcursorpair.
Cursorsarecontrolledandinteractedwithinthefollowingways:
•Selectingacursorpairbuttonactivatesthepair.
•PressingtheRemoveCursorbuttonforthepairdeletesthemfromthedisplay.

•Double‐clickingacursorpairbuttonautomaticallyzoomsandcentersthepairontheWaveformDisplay

Markcursorpairsonsignalsinthewaveformdisplayusingthefollowingsteps:
1. Selectacursorpair(1‐4)fromthetoolsdetailedcontrol.
2. Left‐clickthedisplaytoplacecursorA(ofthepair)atthefirstlocation.
3. Now,right‐clickthedisplaytoplacecursorB(ofthepair)atthesecondlocation.

PLEASENOTETHEFOLLOWING:
•Thetimedifference(andfrequencybetweenAandB)isshownonboththeWaveformDisplayArea
andontheCursor’sTool.
•Whenasinglecursor(ofthepair)isplaced,thetimeandfrequencyisshowninreal‐timebasedon
mousepositionuntilthesecondhalfofthepairisplaced(byright‐clickingonthewaveform).
•Placingthemouseovertheactivecursorpairshowsthehorizontalclick‐and‐dragmouseicon.
Whenthisiconappears,youcanhorizontallyclick‐and‐dragacursortoanewlocation.Thedisplay
valuesareupdatedaccordingly.

•Clickingacreatedcursorinthewaveformdisplayautomaticallyselectsthecursorpairandenables
thecursortool.
•Whenplacingormovingacursoroveranydigitalsignal,thesoftwarelooksforanynearbyedgeson
thesignalandsnapsthecursortothatedge.Thisallowsforeasier,precisemeasurementsbetween
edges.Whenthecursorissuccessfullysnappedtoanedge,thecursor’scolorchangestomatchthe
signal.Snappingdoesnotoccurwhenthemousepointerispositionedaboveorbelowthe
waveform.
•CursorsthatcrossAnalogorDigitalWavesignalsalsodisplaythevalueofthesignalwhereitmeets


RearView
TheRearViewtoolallowsyoutostoreandnavigatethroughahistoryofdataacquisitionsretrievedfromthe
device(s).TheexpandedRearViewtool’sdetailedcontrollookslikethefollowing:

RearViewkeepsahistoryofthelastNacquisitions.ViewyourstoredacquisitionsbysettingyourtriggertoStop
andusingtheslideronthedetailedcontroltoflipthroughthehistory.Thecurrentlyselectedacquisitionis
showninthewaveformdisplayarea.
Youcanchangethenumberofstoredacquisitionsbyprovidinganewnumberinthetextboxattherightendof
thetool’sdetailedcontrol.
ThebluebarontheslidercontroldisplayshowmuchoftheRearViewhistoryisbeingusedandavailablefor
review.Thisbarfillsupasyoumakenewacquisitionsuntilreachingyourspecifieddepth;atwhichpointthe
oldestacquisitionisdiscardedwhenanewoneisreceived.
Note:TheRearViewtoolisalwaysenabled.Thedefaultacquisitiondepthissetto20records.
Thespecificacquisitionbeingviewedisalwaysshownabovetheslidercontrol–forexampleintheprevious
screenshotthetoolisshowingacquisition11of20possibleacquisitions.Whenyouacquireanewacquisition
theRearViewtoolautomaticallyadjuststoshowthemostrecentacquisition.
TIPS:
•WhileusingtheRearViewtool,youcanmodifyyoursignalsetupatanytimeanddisplayadditional
signals/dataindifferentwaysthanhowitmayhavebeensetatthetimeoftheactualsignal
acquisition.
•YoucancreateapersistencedisplaytocompareacquisitionsAFTERallthenecessaryacquisitionshave
beenobtained.Dothisbyenablingpersistencemode,andthennavigatingthroughvarious
acquisitionsavailableintheRearViewtool.Youcanevengenerateapersistencedisplayfora
timeframeorzoomlevel–evenifthesignaldatawasnotyetvisibleatthetimeofacquisition.

Magnifier
TheMagnifiertoolallowsyoutoquicklyzoom‐inonaselectedtime‐periodofyouracquisitionwithouthavingto
adjustyourmaindisplayorloseyourframeofreference.

Enablethemagnifiertoolatanytimebyclickingthemainportionofthecontrol.Now,moveyourmouse
anywhereoverthewaveformdisplayandanadditional,time‐magnifieddisplayisdrawninsideaboxed,
magnifiedarea.Usetheslidercontrolormousewheeltoadjustthemagnificationfactorinsidethetime‐
magnifieddisplay.Thesliderbarupdatesalongwithyourmousewheeladjustments.
Withthemagnifiertoolenabled,youcanstilladjustthetimeframeofthemainwaveformdisplaybyholdingthe
Controlkeydownwhilescrollingthemousewheel,ordraggingwiththeleftandrightmousebuttonsasnormal.
Tip:Thistoolconvenientlyprovidesaquick,magnifiedviewofcloselyalignededgesorvisibilityofdecodeand


WorldView
TheWorldViewisanextremelypowerfulcontroljustabovethewaveformdisplayonthedashboard.Notonly
doesitprovideimportanthigh‐levelwaveforminformation,butitalsoallowsfordisplayconfigurationandeven
pre/post‐storesettings.Thecontrollookslikethefollowing:

