Selects one waveform out of an array of analog or digital waveforms by array index or channel name. The data types you wire to the waveform array and index inputs and the data type of the Y component of the analog waveform determine the polymorphic instance to use.

Inputs/Outputs

  • c1dwdtint.png waveform array —

    waveform array is an array of analog waveforms from which to extract a single waveform.

  • ci32.png index —

    index is the index of the waveform to extract from waveform array.

  • cerrcodeclst.png error in (no error) —

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

  • iwdtint.png waveform —

    waveform is the analog waveform selected from the array of waveforms.

  • ierrcodeclst.png error out —

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