Start and stop trigger for edge counting PXI-6602

[Mroche]

I have a PXI-6602 and an application where I need a start and stop trigger to control an edge counter. Basically I have the input signal and a control signal. The control signal outputs pulses periodically. I need the ability to count the pulses on the input signal between the pulses of the control signal. Can the 6602 handle this?

So far, I have looked into using the pause trigger, but it looks like you can only configure that for a level. You can't configure the pause trigger type to be a digital edge. I've also looked into using the arm start trigger, but once the counter starts I don't see a way to stop it.

I have two 6602 cards and the need to count up to six input signals simulataneously. So I do have two open counters available to aid in this application.

Any help would be greatly appreciated.

Mike,

The easiest way to perform this would be to perform a period measurement (in ticks) on your control signal and use the input signal as the source.  This would give you the number of ticks of the input signal between rising edges of the control signal and would only require one counter for each of your 6 input signals.
