PersistenceSetup

TheanalogPersistencefeaturedisplaysyourwaveformandrevealsitsanomalies

forarepetitivesignal.UsePersistencetoaccumulateon‐screenpointsfrommany

acquisitionstoseeyoursignalchangeovertime.Theinstrumentpersistencemodes

showthemostfrequentsignalpaththree‐dimensionallyinintensitiesofthesame

color,orgra

dedinaspectrumofcolors.

Saturation Level

WhenyouselectAnalog modefromthePersistencedialog,each

channelisassignedasinglecolor.Asapersistencedatamapdevelops,

differentintensitiesofthatcolorareassignedtotherangebetweena

minimumandamaximumpopulation.Themaximumpopulation

automaticallygetsthehighestintensity,theminimumpopulationgets

thelowestintensity,andinter

mediatepopulationsgetintensitiesin

betweentheseextremes.

Seetheon‐lineHelpformoreinformation.

Colormodepersistence,selectedbytouchingColor,worksonthe

sameprincipleastheAnalogpersistencefeature,butinsteadusesthe

entirecolorspectrumtomapsignalintensity:violetforminimum

population,redformaximumpopulation.Asaturationlevelof100%

spreadstheintensityvariationacrosstheentiredistribution.Atlower

saturationlevels,theintensitysaturates(b

ecomesthebrightestcolor)

atthepercentagevaluespecified.Loweringthispercentagecausesthe

pixelstobesaturatedatalowerpopulation,andmakesvisiblethose

rarelyhitpixelsnotseenathigherpercentages.

3-Dimensional Persistence

Byselecting3d,youcancreateatopographicalviewofyourwaveform

fromaselectionofshadings,textures,andhues.Theadvantageofthe

topographicalviewisthatareasofhighestandlowestintensityare

shownaspeaksandvalleys,inadditiontocolororbrightness.The

shapeofthepeaks(p

ointedorflat)canrevealfurtherinformation

aboutthefrequencyofoccurrencesinyourwaveform.

TheinstrumentalsogivesyoutheabilitytoturntheXandYaxesofthe

waveformthrough180°ofrotationfrom‐90°to+90°.
