Here is a wire frame view of the same waveform
in which lines of equal intensity are used to
construct the persistence map.

Show Last Trace

For most applications, you may not want to show the last trace because it will be superimposed on
top of your persistence display. In those cases turn off Show Last Trace by touching the checkbox.
However, if you are doing mask testing and want to see where the last trace is falling, turn Show
Last Trace on.

Persistence Time

You can control the duration of persistence by setting a time limit, in seconds, after which
persistence data will be erased: 0.5 s, 1 s, 2 s, 5 s, 10 s, 20 s, or infinity.

Locking of Traces

The instrument gives you the choice of constraining all input channels to the same mode, saturation
level, persistence time, and last trace display, or setting these for each input channel individually.

Choose

to constrain input channels. Choose

to set up input

channels individually.

To Set Up Persistence

1. In the menu bar touch Display, then touch Persistence Setup... in the drop-down menu.
2. Touch

the

Persistence On checkbox. If Per Trace is selected, touch the Reset All button

to return all input channel setups to their default settings.

3. Touch

the

All Locked button

if you want to set the same mode, saturation

level, persistence time, and last trace display for all input channels. Touch the Per Trace

button

to set these for each input channel individually.

If you selected All Locked, touch one of the mode buttons:
