OAT Overall Level Plot VI

OAT Overall Level Plot VI

Owning Palette: Order Analysis VIs

Requires: Sound and Vibration Toolkit

Computes the root-mean-square (RMS) level of the even-angle signal and generates an XY graph as the output. Wire data to the even-angle signal input to determine the polymorphic instance to use or manually select the instance.

Minimum Data Requirements
This function requires a minimum amount of even angle data before an output will be returned. reset? and integration revolution 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.
	x-axis selection specifies the scale type to use for the x-axis of the output XY plot. 0 Time 1 Revolution 2 RPM (default)
	even-angle signal specifies the even-angle-resampled data. even-angled signal is synchronous to the rotational speed with a constant number of samples per revolution. r0 specifies the starting index value for counting revolutions. dr specifies the revolution interval between two sequential samples. Y specifies the value of the even-angle-spaced sample in a scaled engineering unit.
	even-angle channel info specifies the information about the measurement configuration that this VI uses to acquire the resampled data. Note  You must wire even-angle channel info when performing extended measurements. Do not modify the even-angle channel info values. If you want to view the information, you can create a custom probe.
	even-angle position info specifies the position information of even-angle signal. positions [s] specifies the locations of the samples, in seconds. samples/rev specifies the number of samples per revolution.
	dB on? specifies whether to return the resulting order power spectrum in decibels. If dB on? is FALSE, this VI returns the order power spectrum linearly. The default is TRUE.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	integration revolution specifies the integration length of the even-angle signal in revolution. This VI divides the input even-angle signal into segments by the integration revolution value, and calculates one overall RMS value for each segment. integration revolution must be greater than zero. When integration revolution is less than zero, this VI sets integration revolution to 1. The default is 1.
	overall level returns the overall level of the even-angle signal in root-mean-square units. time/rev/RPM returns the x-axis value of the overall level plot, in time, revolution, or RPM. level returns the y-axis value of the overall level plot in root-mean-square units.
	unit labels returns the unit labels of the overall level plot. x-axis unit returns the x-axis engineering unit of the overall level plot. overall level unit returns the y-axis engineering unit of the overall level plot.
	level position info returns the position information of the overall level. positions [s] returns the locations of the samples in seconds. samples/rev returns the number of samples per revolution.
	error out contains error information. This output provides standard error out functionality.

	overall levels returns the overall levels, for each channel, of the even-angle signals in root-mean-square units. time/rev/RPM returns the x-axis value of the overall levels plot, in time, revolution, or RPM. level returns the y-axis value of the overall levels plot in root-mean-square units.
