To set the

style

6. Touch the DISP button and select the Appearance tab.
7. Select between Vectors, Dots, or Inten Samp display
styles. (Dots is the default setting when in Equivalent
Time (ET) acquisition mode. Vectors is the default when
not in ET acquisition mode.)
8. Select between Off, Variable, and Infinite Display
Persistence. (Off is the factory default setting.)
Variable persistence is explained on page 3--140. No
Persistence erases the display each time a new
waveform array is displayed.
If your instrument supports mask testing, Mask Autofit
can affect persistence. When enabled Autofit moves the
waveform vertically and horizontally to reduce the
number of hits within a given mask. If infinite or variable
persistence is enabled, the movements will clear any
persisted data. If Autofit makes frequent adjustments,
there can be very little or even no persisted data
displayed.
9. If you select Variable, touch Persist Time and adjust the
persistence time (decay rate).
