Inputs/Outputs

  • civrn.png Instrument Handle —

    Instrument Handle identifies a particular instrument session.

    Instrument Handle is obtained from the niFgen Initialize VI, niFgen Initialize With Options VI, or the niFgen Initialize With Channels VI.

  • cstr.png Channel Name —

    Channel Name specifies the channel that this VI uses.

  • ci32.png Waveform Handle —

    Waveform Handle specifies the handle of the arbitrary waveform previously allocated with the niFgen Allocate Waveform VI.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

    Default value: no error

  • cu32.png Window Address —

    Window Address specifies the windows address of the Direct DMA-compatible data source.

  • ci32.png Samples to Write —

    Samples to Write specifies the number of samples to write from the Direct DMA-compatible data source.

  • iivrn.png Instrument Handle Out —

    Instrument Handle Out passes a reference to your instrument session to the next VI.

  • ii32.png Waveform Handle Out —

    Waveform Handle Out returns the handle that identifies the waveform.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
