Issue Details

I need to write a bit stream with a Digital Waveform Instrument like PXI-6541, and then perform a measurement with a Multifunction I/O Module like PXIe-6356. I need to do this many times, so I want to set up a pulse train and use it as a shared trigger.

Solution

To achieve this, you can use Marker events to generate a marker in a specific location in the pattern and export it to a trigger line to trigger the acquisition/generation task in the Multifunction I/O device.

 

The process of generating and exporting the marker events is explained in the example Dynamic Generation with Marker Event.vi. To access this example open LabVIEW, go to Help > Find Examples.... In the Browse tab go to Hardware Input and Output > Modular Instruments > NI HSDIO > Dynamic Generation > Scripted.
