Gated Event Counting
Gated Event Counting is similar to Event Counting except that the counting process is gated. When the
counter gate is active, the counter counts pulses which occur at the counter source. When the counter gate
is inactive the counter retains the current count value. At each sample clock interval the current value is
read.
The gure below shows an example of gated event counting where the counter counts three events on the
counter source. At (1) and (2) the counter value is zero, because the gate signal is inactive. At sample clock
(3), (4) and (5) the actual counter value is read out. At (6) the same value as at (5) is output.

Software setup:
- If counting the falling edges is necessary, the input signal can be inverted.
