Issue Details

I use the RTSI lines for gating and clocking of analog collections. I also need to be able to read the values on these lines with digital inputs for debugging purposes. Is it possible to query the state of the trigger and gating using DIO?
 

Solution

No, it is not possible to query the state of a gate or trigger. See additional information for alternative options.

Additional Information

An alternative to querying the state of a gate is to use a secondary counter that checks if pulses are coming in. If you know when the gate is open or closed, you can monitor the secondary counter to see that the triggers are coming through as expected.
