Owning Palette: Order Analysis VIs

Installed With: Sound and Vibration Measurement Suite

Generates a speed profile from a sound or vibration signal without a tachometer signal.

Example

	scaled signal [EU] contains the scaled signal expressed in the selected engineering units. To obtain a properly scaled signal, you can use the SVL Scale Voltage to EU VI or define a virtual channel in Measurement & Automation Explorer (MAX).
	error in describes error conditions that occur before this node runs. The default is no error. If an error occurred before this node runs, the node passes the error in value to error out. This node runs normally only if no error occurred before this node runs. If an error occurs while this node runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this node ran or FALSE (checkmark) to indicate a warning or that no error occurred before this node ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source specifies the origin of the error or warning and is, in most cases, the name of the node that produced the error or warning. The default is an empty string.
	effective bandwidth returns the bandwidth settings this VI uses to refine speed profile. You can use effective bandwidth as a reference when tracking orders. bandwidth value returns the value of the bandwidth that the Gabor filter uses. bandwidth unit returns the type of bandwidth applied to the signal. 0 Order (Default) 1 Hz
	dup scaled signal [EU] returns the scaled signal [EU] unchanged.
	speed profile returns information about the tachometer pulse arrival time and the rotational speed at each pulse. time [s] returns the arrival time, in seconds, of each tachometer pulse. speed [RPM] returns the rotational speed, in revolutions per minute, of each tachometer pulse.
	orders list returns the list of orders used to refine speed profile.
	error out contains error information. If error in indicates that an error occurred before this node ran, error out contains the same error information. Otherwise, it describes the error status that this node produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error. status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the node that produced the error or warning.
	window info returns the window information for the Gabor transform and expansion. window type returns the type of window used to perform Gabor expansion. 0 None 1 Hanning 2 Hamming 3 Blackman-Harris 4 Exact Blackman 5 Blackman 6 Flat Top 7 4 Term B-Harris 8 7 Term B-Harris 9 Low Sidelobe 10 Gaussian window length returns the length of the applied window.

Example

Refer to the Tachless Order Tracking (Offline) VI in the labview\examples\Order Analysis\Tachless Order Tracking directory for an example of using the OAT Tachless Speed Profile Generator VI.
