Gated event counting is a mode where the counter counts only when the gate signal is high. It is available only with Orion counters. This tutorial is a continuation of the previous "Simple event counting" section.

 

The counter signal is the same as with simple event counting, but we need to connect additionally a second signal - the gate. We should connect the second switch to GATE 0 as well as the DI_1 to see the values (of course it is not necessary to do this when measuring real signal, this it is just for demonstration purposes).

 

Then we perform the setup of the counter channel. We should choose Gated event counting mode and set the signal source, which is Aux_B0_CNT0, and the Signal gate (Gate_B0_CNT0) . The counter will count the transitions from low to high only when the signal gate is high. Since the Signal gate is inverted (normally it is high), it is necessary to also invert the gate signal so it will count only when a button will be pressed.

 

In the example below, we can see how this counter works. The orange signal (counter) counts up when the green signal makes a transition from low to high and when the gate signal (blue) is high .
