Owning Palette: Waveform VIs and Functions
Requires: Base Development System
Computes the duration of waveform in using the following equation: duration = (#samples-1) × dx. Wire data to the waveform in input to determine the polymorphic instance to use or manually select the instance.
Use the pull-down menu to select an instance of this VI.
![]() | open interval? defines the interval over which the input waveform extends. The default is TRUE, which selects an open interval. For example, assume an input waveform contains 3 data elements at t = {0, dt, 2dt}. An open interval defines the waveform as extending over the time interval 0 ![]() ![]() |
![]() | waveform in is the analog waveform for which you want the duration. |
![]() | error in describes error conditions that occur before this node runs. This input provides standard error in functionality. |
![]() | waveform out returns waveform in unchanged. |
![]() | duration is the duration of the waveform. |
![]() | error out contains error information. This output provides standard error out functionality. |
