Installed With: Sound and Vibration Measurement Suite

Retrieves a subset of an even-angle signal at a specified revolution duration. 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 Even Angle Signal Subset (1 Channel)

	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.
	start [rev] specifies the revolution value at which you want to start acquiring a subset of the even-angle signal. The default is 0.00.
	duration [rev] specifies the revolution duration to use to retrieve the subset. The default is 1.00.
	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.
	even-angle signals out returns the subset of the even-angle signal at the specified revolution duration. r0 returns the starting index value for counting revolutions. dr returns the revolution interval between two sequential samples. Y returns the value of the even-angle-spaced sample in a scaled engineering unit.
	dup even-angle channel info returns even-angle channel info unchanged.
	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.
