Align Waveforms (single shot) VI

Owning Palette: Waveform Conditioning VIs

Requires: Full Development System

Performs element-wise alignment of two waveforms and returns the aligned waveforms. The data types you wire to the waveform inputs determine the polymorphic instance to use.

Align N Waveforms (single shot)

exported interval defines the time stamp of the waveform outputs.

0Common (default)
1Global
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 t < 2dt, and a closed interval defines the waveform as extending over the time interval 0 t < 3dt.
waveforms in is an array of waveforms to align.
interpolation mode specifies the interpolation method.

0Coerce—Each output sample is set equal to the input sample value that is closest to it in time.
1Linear (default)—Each output sample value is a linear interpolation between the two input samples that are closest to it in time.
2Spline—Uses the spline interpolation algorithm to compute the resampled values.
3FIR filter—Uses a finite impulse response (FIR) filtering algorithm to compute the resampled values.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
