Owning Palette: Utilities VIs

Installed With: Advanced Signal Processing Toolkit

Converts the unit of an input univariate or multivariate (vector) time series from volts to an engineering unit (EU). Wire data to the Xt input to determine the polymorphic instance to use or manually select the instance.

Details  Example

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

TSA Scale to EU (single-channel)

	Xt specifies the input univariate time series.
	scale info specifies information about the measurement system used before the signal reaches the data acquisition (DAQ) device. sensor sensitivity [mV/EU] specifies the sensitivity of the sensor in mV/EU. engineering unit specifies the engineering unit to which you want to scale. The default is V. custom label specifies a label for the custom engineering unit.
	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function 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 VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function 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 VI or function that produced the error or warning. The default is an empty string.
	Xt out returns the scaled univariate time series expressed in specified scale information.
	unit returns the name of the specified engineering unit.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function 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 VI or function that produced the error or warning.

TSA Scale to EU (multi-channel)

	Xt specifies the input multivariate (vector) time series.
	scale info specifies information about the measurement system used before the signal reaches the DAQ device. Each element of the array represents one setting for one channel. scale info contains the following elements: sensor sensitivity [mV/EU] specifies the sensitivity of the sensor in mV/EU. engineering unit specifies the engineering unit to which you want to scale. The default is V. custom label specifies a label for the custom engineering unit.
	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function 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 VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function 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 VI or function that produced the error or warning. The default is an empty string.
	Xt out returns the scaled multivariate (vector) time series expressed in specified scale information.
	unit returns the name of the specified engineering units. Each element of the array represents one unit for one channel.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function 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 VI or function that produced the error or warning.

TSA Scale to EU Details

Use the TSA Scale To Unit VI to analyze a time series for engineering purposes, such as vibration testing.

Note  If the unit of the input time series is scaled from volts to another engineering unit prior to reaching this VI, this VI does not perform any additional scaling. Therefore, this VI ignores any scaling information specified in scale info, such as sensor sensitivity [mV/EU] or engineering units and reads the engineering unit from the attributes of the input signal.

Example

Refer to the Average PSD VI in the labview\examples\Time Series Analysis\TSAGettingStarted.llb for an example of using the TSA Scale to EU VI.
