OAT Get Even Angle Reference VI

Owning Palette: Reference Data Processing VIs

Installed With: Sound and Vibration Measurement Suite

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. The data type you wire to the scaled signal [EU] input determines the polymorphic instance to use.

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

OAT Get Even Angle Reference (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.
reference output mode specifies the output mode of the even-angle reference.
0averaged samples—(Default) Specifies that this VI uses N-revolution-averaged even-angle samples as the reference, where N is the number of revolutions in even-angle reference. You specify the number of revolutions in # of revs in reference.
1initial samples—Specifies that this VI uses the first N revolution even-angle samples as the reference.
2final samples—Specifies that this VI uses 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 Measurement & Automation Explorer (MAX).
speed profile specifies the arrival time and the rotational speed of each tachometer pulse.
time [s] specifies the arrival time, in seconds, of each tachometer pulse.
speed [RPM] specifies the rotational speed, in revolutions per minute, of each tachometer pulse.
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. 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.
max order specifies the maximum order to analyze. If max order is less than or equal to 0, this VI automatically sets a maximum order to analyze. The default is 0.
remove DC? specifies whether to remove DC component in the even-angle reference. The default is FALSE.
even-angle reference returns the even-angle-spaced signal reference.
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.
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.
actual max order returns the actual maximum order this VI uses.

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.

0averaged samples—(Default) Specifies that this VI uses N-revolution-averaged even-angle samples as the reference, where N is the number of revolutions in even-angle references. You specify the number of revolutions in # of revs in reference.

even-angle references returns the even-angle-spaced signal reference for each channel.
