Display persistence
From the Display menu, select Display Setup; then open the Appearance tab.
To use
Click one of the buttons to select the display persistence.
Click Infinite (persistence) to continuously accumulate record points on the waveform until you
change one of the acquisition display settings.
Click Variable; then click in the Time entry box and use the multipurpose knobs to set the
persistence time.
Click Reset to clear the persistence.

Behavior
Use infinite persistence for displaying record points that m ay occur outside the normal acquisition
envelope.
Use Variable to accumulate record points on the waveform for a specified time interval. Each
record point decays independently according to the time interval.
If you click Off, the waveform record points appear for the current acquisition only.
TIP. Use the Display menu Display Persistence submenu or right-click in the graticule and select
Display Persistence from the shortcut menu to directly access the persistence options.
