Requires: Advanced Signal Processing Toolkit

Converts the unit of a 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 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 node runs. This input provides standard error in functionality.
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. This output provides standard error out functionality.

TSA Scale to EU (Multi-Channel)

Xt specifies the 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 node runs. This input provides standard error in functionality.
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. This output provides standard error out functionality.

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 directory for an example of using the TSA Scale to EU VI.
