Owning Palette: Utility VIs

Installed With: Sound and Vibration Measurement Suite

Generates triggered even-angle signals for vector averaging in order power spectrum calculations. The data type you wire to even-angle signal determines the polymorphic instance to use.

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

OAT Output Triggered Even Angle Signal (1 Channel)

	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.
	block size specifies the block size of the triggered even-angle signal. You can set block size to the same value that is used to compute the order power spectrum. The default value is -1, which causes this VI to set block size to the number of samples contained in the number of revolutions specified in trigger period [rev].
	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.
	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.
	trigger period [rev] specifies the interval between triggers in revolutions. The default is 1.
	triggered even-angle signal returns the triggered even-angle signal. 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.
	even-angle channel info out returns information about the measurement configuration for even-angle signal.
	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.

	even-angle channel info specifies information about the measurement system for multiple channels of even-angle signals. Do not change the values in even-angle channel info.
	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.

	triggered even-angle signals returns the triggered even-angle spaced samples computed by resampling.
