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
Display/Persist
on the front panel to enter the DISPLAY function menu.
2.
Press the
Persist
F key; then turn the
Universal Knob
to choose the setting:
l
Off
—turn of persistence.
l
Variable persistence time
(1 second, 5 seconds, 10 seconds, 30 seconds ) — how long prior
waveforms persist. Older waveforms are erased after this delay.
l
Infinite
—select “Infinite” Results of previous acquisitions are never erased. Use infinite
persistence to measure noise and jitter, see the worst-case extremes of varying waveforms,
look for timing violations, or capture rare events.

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