Create Visual Trigger areas

The Visual Trigger function extends standard triggering by letting you easily draw and define areas on the screen to further

qualify trigger conditions. This procedure describes how to enable the visual trigger mode and draw areas on the screen.

1. Set the standard trigger conditions to trigger on and display the waveforms to which you want to add visual trigger areas.

2. Double-tap the Draw-a-Box icon (lower right of screen near the Garbage Can icon).

which it was added (in Stacked mode) or the active channel (in Overlay mode), and assigned the default area logic condition

of In (the area is true when the waveform intersects any part of the area).

6. Continue drawing rectangles to add other visual trigger areas:

a. If in Stacked mode, you can draw visual trigger areas in different waveform slices.

b. If in Overlay mode, select a channel before creating areas for that channel.

7. When you are done drawing visual trigger areas, single-tap anywhere to end the area draw function.

8. To draw areas again, tap the Draw-A-Box vt icon again.

9. To change the shape of an area, see Edit visual trigger areas on the screen on page 133 and Edit visual trigger areas using

the Area menu on page 135.
