Waveform Nodes

Create waveforms and access their components.

Align Waveform Timestamps
Replaces the timestamp value (t0) of each waveform in waveform array with the timestamp value of the waveform at the index position you specify.
Copy Waveform dt
Replaces the dt value of each waveform in the waveform array with the dt value of the waveform at the index position you specify.
Get Final Time Value
Returns the ending time value of the specified waveform. The formula this node uses is xf = x0 + duration of the specified waveform.
Get Waveform Subset
Retrieves a subset of a waveform at a specified time or index.
Get Waveform Time Array
Creates an array of timestamps based on the specified waveform.
Get XY Value
Returns the X and Y value of a waveform or digital data set.
Index Waveform Array
Selects one waveform out of an array of analog or digital waveforms by array index or channel name.
Scale Delta t
Multiplies the delta t component of the waveform by the specified scale factor, which lengthens or shortens the sample rate of the waveform.
Waveform Duration
Computes the duration of the specified waveform using the following equation: duration = (number of samples-1) x dx.
