InterpolationSettings
Linearinterpolation,whichinsertsastraightlinebetweensamplepoints,isbest
usedtoreconstructstraight‐edgedsignalssuchassquarewaves.(Sinx)/x
interpolation,ontheotherhand,issuitableforreconstructingcurvedorirregular
waveshapes,especiallywhenthesamplerateis3to5timesthesystembandwidth.
NoiseFiltering(ERES)
Theinstrument'senhancedresolutionfeatureimprovesverticalresolutionbya
fixedamountforeachfilter.Thisrealincreaseinresolutionoccurswhetherornot
thesignalisnoisy,oryoursignalissingle‐shotorrepetitive.
Thesignal‐to‐noiseratio(SNR)improvementyougainisdependentontheformof
thenoiseintheoriginalsignal.Theenhance
dresolutionfilteringdecreasesthe
bandwidthofthesignal,filteringoutsomeofthenoise.
UsingToolbarShortcuts
Thesetoolbarshortcutscanbeusedtoperformspecificactionsforthechannel
correspondingtothecurrentsetupdialog.
FormoreinformationonMeasure,Zoom,Math,andMemories(Reference
Waveforms),refertothesectiondealingwiththatsubject.
OpensaMeasurementselectionpop‐upmenu.Youcanthenselect
upto6parameters(measurements)fortheactivechannelfrom
thismenuwithoutleavingtheChannelSetupdialog.Theparameter
automaticallyappearsbelowthegrid.
Createsazoomtraceofthechannelsignal.Thezoomtrace
becomesactive,andyoucanusetheVerticalandHorizontal
controlstomodifyitsscaleandposition.
OpensaMathselectionpop‐upmenu.Youcanthenselectamath
functionfortheactivechannelfromthismenuwithoutleavingthe
ChannelSetupdialog.TheMathtraceisthendisplayedinitsown
grid.
CopiesthechanneltraceintoitscorrespondingMemory(Reference
Waveform)location.Forinstance,C1isloadedintoM1,C2is
loadedintoM2,etc.
Automaticallyperformsaverticalscalingthatfitsthewaveform
intothegrid.
OpensaLabelingpop‐upmenuthatallowsuser‐definedlabelstied
tothewaveform.
