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)... ).
