OAT Get Even Angle Reference VI

OAT Get Even Angle Reference VI

Owning Palette: Reference Data Processing VIs

Requires: Sound and Vibration Toolkit

Computes the even-angle reference of the scaled signal [EU]. The output reference is the even-angle spaced signal with a constant number of samples per revolution. Wire data to the scaled signal [EU] input to determine the polymorphic instance to use or manually select the instance.

OAT Get Even Angle Reference (1 Ch)

	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.
	reference output mode specifies the output mode of even-angle reference. 0 averaged samples (default)—Specifies that the VI specifies N revolution averaged even angle samples as the reference, where N is the number of revolutions in even angle reference determined by # of revs in reference. 1 initial samples—Specifies that the VI specifies the first N revolution even angle samples as the reference. 2 final samples—Specifies that the VI specifies the last N revolution even angle samples as the reference.
	scaled signal [EU] specifies 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 National Instruments Measurement & Automation Explorer (MAX). t0 specifies the start time of the waveform. dt specifies the time interval in seconds between data points in the waveform. Y specifies the data values of the waveform.
	speed profile specifies the tachometer-pulse arrival time and the rotational speed at each pulse. time [s] specifies the time instant of pulses in seconds. speed [RPM] specifies the rotational speed at each pulse time instant in revolutions per minute.
	pulse/revolution specifies the number of pulses the tachometer generates during each revolution. The default is 1.
	# of revs in reference specifies the number of revolutions in the even-angle reference. The default is 1.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	max order specifies the maximum order to analyze. If max order is less than or equal to zero, this VI automatically sets a maximum order to analyze. The default is 0.
	remove DC? specifies whether to remove the DC component in the even-angle reference. The default is FALSE.
	even-angle reference returns the even-angle spaced signal reference. r0 returns the start of the revolution index. dr returns the revolution interval between two sequential samples. Y returns the values of even-angle spaced samples in a scaled engineering unit.
	error out contains error information. This output provides standard error out functionality.
	actual max order is the actual measured maximum order this VI uses. actual max order is calculated using max order and pulse/revolution:

	even-angle references returns the even-angle spaced signal reference for each channel. r0 returns the start of the revolution index. dr returns the revolution interval between two sequential samples. Y returns the values of even-angle spaced samples in a scaled engineering unit.
