Event Counting
In Event Counting the counter counts the number of pulses that occur on counter source. At each sample
clock the counter value is read without disturbing the counting process. The gure below shows an example
of event counting where the counter counts eight events on Counter Source. The synchronized value is the
value read at the sample clock (see the encircled numbers in the gure, e.g. (1), (2), (3)... ).
