Window trigger can be used to trigger when the input signal enters a window or leaves a window.

To trigger based on a window, the system has an adjustable window of which the upper and lower level can be adjusted individually. The trigger system will constantly compare the input signal with the upper and lower level of the window.

When using Outside window triggering, the system will generate a trigger as soon as the signal becomes larger than the upper level of the window or smaller than the lower level of the window, in other words: is outside the window.

When using Inside window triggering, the system will generate a trigger as soon as the signal becomes larger than the lower level of the window and smaller than the upper level of the window, in other words: is inside the window.

In the software, the upper level is controlled by the trigger level. The position of the lower level is controlled by the trigger level and the size of the trigger hysteresis.

In the image below, Outside window triggering is shown.
