OAT Convert Speed Waveform to Speed Profile VI

OAT Convert Speed Waveform to Speed Profile VI

Owning Palette: Tachometer Processing VIs

Requires: Sound and Vibration Toolkit

Use this VI to convert a saved history of speed data sampled at regular time intervals to a speed profile suitable for order analysis with the Sound and Vibration Measurement Suite VIs.

Minimum Data Requirements
This function requires a minimum amount of tachometer speed data before an output will be returned. pulse/revolution and reset? inputs will affect the amount of data required before an output is returned.

	reset? specifies the initialization of the internal states. The first time this VI runs, or when reset? is TRUE, the internal states initialize to zero. If reset? is FALSE, this VI sets the internal states to the final states from the previous call to the VI. The default is FALSE.
	speed waveform is the time history of speeds such as that recorded from a SCADA recording system. Units are in RPM versus time. dt is the interval between samples and t0 is the timestamp of the first sample.
	pulse/revolution specifies the number of pulses the tachometer generates during each revolution. The default is 1.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	speed profile returns information about the tachometer pulse arrival time and the rotational speed at each pulse. time [s] returns the time instant of pulses in seconds. speed [RPM] returns the rotational speed at each pulse time instant in revolutions per minute.
	error out contains error information. This output provides standard error out functionality.
