To place the trigger in memory
In Automatic Acquisition Mode, the exact location of the trigger depends on
the trigger specification but usually falls around the center. You can
manually place it to be at the beginning, end, or anywhere else.

In the Analyzer Trigger menu, select Acquisition Control.
The Acquisition Control menu pops up. If the acquisition mode is set to
Automatic, the menu contains a single field and an explanation. If Acquisition
has been customized, it has 3 or 4 fields and a picture showing where the
trigger is currently placed in memory.

If the mode is Automatic, select the field to toggle it to Manual.
The menu now shows three fields and a picture.

analyzer to not save any data before the time delay has elapsed. User Defined
calls up a fourth field where you specify exactly where you want the trigger.
