Owning Palette: Octave Extended Measurements VIs

Installed With: Sound and Vibration Measurement Suite

Applies the selected weighting to a previously computed octave spectrum or spectra. The data type you wire to the octave spectrum input determines the polymorphic instance to use.

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

SVT Weighting Filter (octave) (1 Octave Spectrum)

	octave spectrum specifies the octave spectrum to perform the operation on, in band power versus nominal frequencies. nominal frequencies [Hz] specifies the nominal, or preferred, frequencies as opposed to the exact frequencies associated with each 1/n octave band. band power specifies the band power in decibels associated with each 1/n octave band.
	weighting specifies the type of weighting applied to the octave spectrum. The weighting is applied to the spectrum in the frequency domain. Use Linear if no weighting is needed. Linear (default) A-weighting B-weighting C-weighting
	octave info in contains information about the octave spectrum.
	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 exception control 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.
	weighted octave spectrum returns band power versus nominal frequencies after a weighting filter has been applied. nominal frequencies [Hz] returns the nominal, or preferred, frequencies as opposed to the exact frequencies associated with each 1/n octave band. band power returns, in decibels, the band power associated with each 1/n octave band, if dB On is TRUE.
	unit label returns the selected engineering units.
	total band power returns the total band power in decibels for the channel.
	octave info out returns information about the octave spectrum.
	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.

	octave spectra specifies the octave spectra to perform the operation on, in band power versus nominal frequencies. nominal frequencies [Hz] specifies the nominal, or preferred, frequencies as opposed to the exact frequencies associated with each 1/n octave band. band power specifies the band power in decibels associated with each 1/n octave band.
	weighting specifies the type of weighting applied to the octave spectrum. The weighting is applied to the spectrum in the frequency domain. Use Linear if no weighting is needed. Linear (default) A-weighting B-weighting C-weighting
	octave info contains information about the octave spectra that you can pass from another VI. Do not change the values in octave info. If you want to view the information, you can create a custom probe.
	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.

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.
	weighted octave spectra returns the weighted octave spectra. nominal frequencies [Hz] returns the nominal, or preferred, frequencies as opposed to the exact frequencies associated with each 1/n octave band. band power returns, in decibels, the band power associated with each 1/n octave band, if dB On is TRUE.
	unit labels returns the unit label for each channel.
	total band powers returns the total band power in decibels for each channel.
	octave info out contains the octave information for each 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.
