Figure 11-7. Analog Edge Triggering with Hysteresis Falling Slope Example
• Analog Window Triggering—An analog window trigger occurs
when an analog signal either passes into (enters) or passes out of
(leaves) a window defined by two voltage levels. Specify the levels by
setting the window Top value and the window Bottom value.
Figure 11-8 demonstrates a trigger that asserts when the signal enters
the window.

High threshold
(Level + Hysteresis)
Low threshold
(Level)
First signal must go
above high threshold.
Then signal must go below low threshold
before Analog Comparison Event asserts.
