11.3 Persistence
With persistence enabled, 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.
Waveform persistence is kept only for the current display area; you cannot pan
and zoom the persistence display.
To enable persistence:
Step 1.
Press the
key to enter the
Display
menu.
Step 2.
Press the
softkey to select the persistance type.
• Turn the
to select the persistance type:
OFF:
Turns off persistence.
Time:
Results of previous acquisitions are erased after a certain amount of time (1 second, 5
seconds, 10 seconds, 30 seconds ).Time persistence provides a view of acquired data
that is similar to analog oscilloscopes.
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 events that occur infrequently.
Step 3.
When the Persist is On, press the Clear Persist softkey to erase the results of previous acquisitions
from the display. The oscilloscope will start to accumulate acquisitions again.
Step 4.
To return to the normal display mode, turn off persist and the previous acquisitions will be clear
at once
11.4 Clear Display
To clear all waveforms displayed on the screen and acquire and display new waveforms:
Step 1.
Press the
key to enter the
DISPLAY
menu.
Step 2.
Press the
softkey to navigate to page
2/3
of the
DISPLAY
menu.
Step 3.
Press the
softkey to clear all waveforms.
