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.
