OAT Even Angle Signal Sample Rate Conversion VI

Owning Palette: Utility VIs

Installed With: Sound and Vibration Measurement Suite

Converts the sample rate of the even-angle signal. The data type you wire to the even-angle signal in input determines the polymorphic instance to use.

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

OAT Even Angle Signal Sample Rate Conversion (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.
even-angle signal specifies data resampled at even-angle intervals. even-angle signal is synchronous to the rotational speed with 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.
new dr specifies the sampling interval for the even-angle signal this VI returns. 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.
interpolation mode specifies the resampling algorithm used for the resampling.
0coerce—Specifies that each output sample is set equal to the input sample value that is closest to it in time.
1linear—(Default) Specifies that each output sample value is a linear interpolation between the two input samples that are closest to it in time.
2spline—Specifies that this VI uses the spline interpolation algorithm to compute the resampled values.
3FIR filter—Specifies that this VI uses a finite impulse response (FIR) filtering algorithm to compute the resampled values.
FIR filter specifications specifies the minimum values this VI needs to specify the FIR filter.
alias rejection [dB] specifies the minimum attenuation level of signal components aliased after any resampling operation. The default is 120.00.
normalized bandwidth specifies the fraction of the new sampling rate that is not attenuated. The default is 0.4536.
even-angle signal out returns the new sample rate 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 system for even-angle signal out.
even-angle position info out returns the position information of even-angle signal out.
positions [s] returns the locations of the samples, in seconds.
samples/rev returns the number of samples in each 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.
