Issue Details

I would like to implement an application that collects data from the PXIe-4330 if the analog edge voltage from the PXIe-4492 is greater than 1 V using DAQ Assistant in LabVIEW. However, I couldn't find this feature like sending trigger in the DAQ Assistant. How can I implement it?


Unfortunately, you can't send a trigger signal using the DAQ Assistant because the DAQ Assistant does not support sending trigger function. If you want to generate a trigger signal, you should use the DAQmx Export Signal(VI) . DAQmx Export Signal (VI) is supporting the function routing a control signal to the terminal you specify. The output terminal can reside on the device that generates the control signal or on a different device. As this function, you can share the clock and trigger among multiple tasks and device.
