Returns the X and Y value of a waveform or digital data set. The data type you wire to the waveform in input and the data type of the Y component of the analog waveform determine the polymorphic instance to use.

Inputs/Outputs

  • cdigtblrn.png digital data in —

    digital data in is the set of digital data for which you want to retrieve the X and Y values.

  • cu32.png Start —

    Start is the data element or time value where you want to start acquiring X and Y values.

  • cerrcodeclst.png error in (no error) —

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

  • ii32.png Compressed Index —

    Compressed Index returns the index of the data element or time value with respect to the compressed waveform. For example, if the actual sample number is 8 but the sample is compressed in a portion of the waveform that starts at 3, the compressed index is 3.

  • idigtblrn.png digital data out —

    digital data out returns digital data in unchanged.

  • ii32.png Sample Number —

    Sample Number returns the sample number of the data element or time value. If the value of Start is inside a compressed portion of the waveform, Sample Number is the sample number calculated as if the waveform was not compressed.

  • i1du8.png digital value —

    digital value returns an array of Y values.

  • ierrcodeclst.png error out —

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

  • idigtblrn.png digital data value —

    digital data value returns the values of the digital data.
