Display Settings 8Keysight InfiniiVision 2000 X-Series Oscilloscopes User's Guide 115To set or clear persistenceWith persistence, the oscilloscope updates the display with new acquisitions, butdoes not immediately erase the results of previous acquisitions. All previousacquisitions are displayed with reduced intensity. New acquisitions are shown intheir normal color with normal intensity.Waveform persistence is kept only for the current display area; you cannot panand zoom the persistence display.To use persistence:1 Press the [Display] key.2 Press Persistence; then, turn the Entry knob to select between:• Off — turns off persistence.When persistence is off, you can press the Capture Waveforms softkey toperform a single-shot infinite persistence. A single acquisition's data isdisplayed with reduced intensity, and it remains on the display until youclear persistence or clear the display.• ∞ Persistence — (infinite presistence) Results of previous acquisitions arenever erased.Use infinite persistence to measure noise and jitter, to see the worst-caseextremes of varying waveforms, to look for timing violations, or to captureevents that occur infrequently.• Variable Persistence — Results of previous acquisitions are erased after acertain amount of time.Variable persistence gives you a view of acquired data that is similar toanalog oscilloscopes.When variable persistence is selected, press the Time softkey and use theEntry knob to specify the amount of time that previous acquisitions are to bedisplayed.The display will begin accumulating multiple acquisitions.
