Setting the display persistence
Select Display >Display Persistence, and
then select the type of persistence.
■
No persistence shows record points for
the current acquisition only. Each new
waveform record replaces the previously
acquired record for a channel.
■
Infinite persistence continuously
accumulates record points until you
change one of the acquisition display
settings. Use for displaying points that
may occur outside the normal acquisition
envelope.
■
Variable persistence accumulates record
points for a specified time interval. Each
record point decays independently
according to the time interval.
■
Reset persistence clears the persistence.
1. To set the variable persistence time,
select Display >DisplayPersistence
>Persistence Controls....
2. Click Variable, Persist Time, and then
use the multipurpose knobs to set the
persistence time.
