Converts acceleration to velocity or displacement. You can use this polymorphic VI to integrate a single spectrum or N spectra. The data type you wire to the spectrum input determines the polymorphic instance to use.

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

SVL Integration (frequency) (1 Spectrum)

	length units should be used to specify the desired units for length in the integrated spectrum. Use this parameter to change the base units for the integrated spectrum. no change m (default) mm micron in mil
	spectrum is the frequency-domain data and contains the frequency scaling and the magnitude of the spectrum. f0 specifies the start frequency, in hertz, of the spectrum. df [Hz] specifies the frequency resolution of the spectrum expressed in hertz. magnitude specifies the magnitude of the spectrum.
	integration type specifies the type of integration to perform. 0 Single integration—Returns the velocity if the input is acceleration. 1 Double integration (default)—Returns the displacement if the input is acceleration.
	spectrum info in specifies the properties of the previously computed spectrum. spectrum info in includes the channel name, spectrum type, spectrum scale as linear or dB, applied window, window size, FFT size, units, x-axis units, dB reference, applied weighting, peak units, and spectral density. Note  You must connect spectrum info in when performing extended measurements. Do not modify the spectrum info in values.
	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. Refer to Controlling Error Notification to treat what is normally an error as no error or to treat a warning as an error. 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.
	integrated spectrum contains the integrated spectrum. f0 returns the start frequency, in hertz, of the spectrum. df [Hz] returns the frequency resolution of the spectrum expressed in hertz. magnitude is the magnitude of the integrated spectrum.
	unit label returns the selected engineering units.
	spectrum info out returns the properties of the computed spectrum. spectrum info out includes the channel name, spectrum type, spectrum scale as linear or dB, applied window, window size, FFT size, units, x-axis units, dB reference, applied weighting, peak units, and spectral density. Do not modify the spectrum info out values.
	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.

	length units should be used to specify the desired units for length in the integrated spectrum. Use this parameter to change the base units for the integrated spectrum. no change m (default) mm micron in mil
	spectra contains the frequency-domain data for each spectrum. spectrum is the frequency-domain data and contains the frequency scaling and the magnitude of the spectrum. f0 specifies the start frequency, in hertz, of the spectrum. df [Hz] specifies the frequency resolution of the spectrum expressed in hertz. magnitude specifies the magnitude of the spectrum.
