WAVEFORMMEASUREMENT S
MeasuringwithCursors
Overview
Cursorsareimportanttoolsthataidyouinmeasuringsignalvalues.Cursorsare
markers—lines,cross‐hairs,orarrows—thatyoucanmovearoundthegridorthe
waveformitself.Usecursorstomakefast,accuratemeasurementsandtoeliminate
guesswork.Therearetwobasictypes:
• Horizontal(TimeorFreq
uency)cursorsarelinesthatyoumovehorizontally
alongthewaveform.Placethematadesiredlocationalongthetimeaxisto
readthesignal’samplitudeattheselectedtime.
• Vertical(Voltage)cursorsarelinesthatyoumoveverticallyonthegridto
measuretheamplitudeofasignal.
Cursor Measurement Icons
TheShowiconsdepictwhatisbeingmeasuredforeachmeasurementmode.
Absolute

Eachcursorlocatesapointonthewaveform.Thecursor
valuescanbereadinthedescriptorlabelforthetrace.
UsethePositionfieldsattherightsideofthedialogto
placethecursorsprecisely.
Delta

ThisisthedifferenceinYvalues.Thevaluecanberead
inthedescriptorlabelforthetrace.
Abs+Delta

Displaysabsoluteanddeltacursorstogether.
Slope

Thisgivestheslopebetweencursors.
Iftherearenon‐time‐domainwaveformsdisplayed,amenuisshownoffering
choicesofx‐axisunits:sorHz,forexample.
