I am unclear from reading the documentation for the 6713 D/A board if it is possible to get
a sync pulse from the PFI 6 Output when the board is triggered by software. We would like
to get a pulse to trigger our oscilloscope when the software (CVI) outputs a waveform using
DAQmxWriteAnalogF64().
Thanks,
Jim

Jim,
One way to do this would be to synchronize outputting a digital pulse to PFI6 with your analog output. There are several shipping examples you can consult to set this up. To access these, open the NI Example Finder in CVI and navigate to Hardware Input & Output » DAQmx.
Writing an analog waveform:
» Analog Generation » Voltage » ContGen-IntClk.prj
Writing an digital pulse:
» Digital Generation » WriteDigChan.prj
Synchronizing the task (note this is for reading, you'll need to modify it with the code for writing above):
» Synchronization » Multi-Function » ContAI-ReadDigChan.prj
