Persistence
With persistence, the oscilloscope updates the display with new acquisitions, but
does not immediately erase the results of previous acquisitions. All previous
acquisitions are displayed with reduced intensity. New acquisitions are shown in
their normal color with normal intensity.
Do the following steps to set and clear persistence:
1. Press the
Display/Persist button on the front panel to enter the DISPLAY

2. Press the Persist softkey; then turn the Universal Knob to select the desires

— select different persistence time, the results of previous acquisitions are
erased after a certain amount of time
Infinite —select “Infinite” Results of previous acquisitions are never
erased. Use infinite persistence to measure noise and jitter, to see the
worst- case extremes of varying waveforms, to look for timing violations,
or to capture events that occur infrequently.
