Tips

Using putsample is a good way to test your analog output configuration. Additionally:

  • putsample does not store samples in the data acquisition engine.

  • putsample can be executed at any time after channels have been added to obj.

  • putsample is not supported for sound cards and Dynamic Signal Acquisition and Generation (DSA) cards.

    Note:   Refer to the Hardware Limitations by Vendor section before you access National Instruments devices with the NI-DAQmx adaptor simultaneously from multiple applications.
