Owning Palette: Waveform VIs and Functions

Requires: Base Development System

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.

Example

Use the pull-down menu to select an instance of this VI.
