Owning Palette: Order Analysis VIs

Installed With: Sound and Vibration Measurement Suite

Computes the root-mean-square (RMS) level of the even-angle signal and generates an XY graph as the output. The data type you wire to the even-angle signal input determines the polymorphic instance to use.

Use the pull-down menu to select an instance of this VI.

OAT Overall Level Plot (1 Channel)

	reset? specifies the initialization of the internal states. If reset? is TRUE, or when the VI first runs, 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 graph. 0 Time 1 Revolution 2 RPM (Default)
	even-angle signal specifies the even-angle-resampled data. even-angle 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. Do not change the values in even-angle channel info.
	even-angle position info specifies the position information of the even-angle signal. positions [s] specifies the locations of the samples, in seconds. samples/rev specifies the number of samples in one revolution.
	dB on? specifies whether to return the overall level in decibels. If dB on? is FALSE, this VI returns the overall level linearly. The default is FALSE.
	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.
	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 levels 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 in one revolution.
	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.
