Behavior. The cursor units depend on the cursor type. The cursor position readouts appear on the display graticule. When using
the IRE graticule style, amplitude cursor readouts are shown in IRE units.
Cursor position does not change if the cursor source changes or if the waveform is repositioned.
TIP. Use the pop-up keypad or your external keyboard to specify exact numerical cursor coordinates.

Behavior.
â–
Use infinite persistence for displaying record points that may occur outside the normal acquisition envelope.
â–
Use Variable to accumulate record points on the waveform for a specified time interval. Each record point decays
independently according to the time interval.
â–
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.
