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 function
menu.
2. Press the Persist softkey; then turn the Universal Knob to select the desires option.
Off —turn of persistence.
Variable persistence time (1 second, 5 seconds, 10 seconds, 30 seconds ) —
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.

3. When the Persist is On, to erase the results of previous acquisitions from the display,
press the Clear Persist softkey. The oscilloscope will start to accumulate
acquisitions again.
4. To return to the normal display mode, turn off persist and the previous acquisitions will
be clear at once.
