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 11-7 demonstrates a trigger that asserts when the signal enters the
window.
