  • cu32.png Waveform Size —

    Waveform Size specifies the size of the waveform in samples.

  • 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.

  • cstr.png Waveform Name —

    Waveform Name specifies the name of the waveform.

  • 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

  • iivrn.png Instrument Handle Out —

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

  • istr.png Waveform Name Out —

    Waveform Name Out passes the name of the named waveform.

  • ierrcodeclst.png error out —

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