When you turn the TRIGGER POSITION control counterclockwise, the trigger point () is shifted to the right. This allows you to look at the signal before the trigger point. The pretrigger view is displayed in the bottom of the screen, and calibrated in divisions. The trigger point is indicated on the screen with an arrow. Pretrigger recording can be adjusted and is limited to one full screen, or -10 divisions.

-Turn the TRIGGER POSITION control clockwise.
