The system will not process a trigger signal in the following situations:
•
Whenever a second trigger signal occurs within the “debounce” time of
the first signal. (In this case, there is no Trigger NAK signal, and no
“missed trigger” is counted.)
•
When the “ Overlap Acq/Insp ” function is disabled, and a second trigger
signal occurs before the system has finished the inspection cycle started
by the first trigger signal. In this case, the trigger NAK signal occurs.
•
When the “ Overlap Acq/Insp ” function is enabled, and a second trigger
signal occurs before the system has finished the image acquisition cycle
started by the first trigger signal. In this case, the trigger NAK signal
occurs.
