ADLINK PCIe-7350 - Manual (Page 76)

66 Function Block and Operation Theory
3.9.5 Event Out
PCIe-7350’s Application Function I/O (AFI) can be configured as
event output of pattern match or COS (Change of State).
Pattern Match event is a pulse signal generated while the PCIe-
7350’s digital data input lines matching the pre-defined pattern.
COS (Change of State) event is a pulse signal generated while the
PCIe-7350 detects a change on the pre-defined data input line.
The pulse width of Event Out signal can be configured from 8ns to
34.359738368 sec. (8 ns x N, where N is from 1 to 2
32
-1)
You can export this event out signal to trigger external devices for
synchronization purpose or inform external device.
