Owning Palette: Spectrum Extended Measurements VIs

Requires: Sound and Vibration Toolkit

Use this polymorphic VI to convert spectra to a class data type that you can view on the Spectrum with Cursors XControl. You must manually select the polymorphic instance to use.

SV Convert Spectrum to Data Object

spectrum specifies the frequency-domain data, which contains the frequency scaling and the magnitude of the spectrum.
f0 specifies the start frequency, in hertz, of the spectrum.
df specifies the frequency resolution of the spectrum expressed in hertz.
magnitude specifies the magnitude of the spectrum.
spectrum info specifies properties of the computed spectrum.
Note You must wire spectrum info when performing extended measurements. Do not modify the spectrum info values. If you want to view the information, you can right-click the spectrum info wire and select Custom Probe»Spectrum Info from the shortcut menu.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
spectrum data returns the spectrum converted into a class. The class contains the spectrum and spectrum info. The class enables header information to appear on the cursor table of the Spectrum with Cursors XControl.
error out contains error information. This output provides standard error out functionality.

SV Convert Spectra to Data Object

spectra specifies the frequency-domain data for each spectrum.
f0 specifies the start frequency, in hertz, of the spectrum.
df specifies the frequency resolution of the spectrum expressed in hertz.
magnitude specifies the magnitude of the spectrum.
spectra info specifies properties of the computed spectrum.
Note You must wire spectrum info when performing extended measurements. Do not modify the spectrum info values. If you want to view the information, you can create a custom probe.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
spectrum data returns the spectrum converted into a class. The class contains the spectrum and spectrum info. The class enables header information to appear on the cursor table of the Spectrum with Cursors XControl.

SV Convert Complex Spectrum to Data Object

complex spectrum specifies the complex spectrum response.
f0 specifies the start frequency, in hertz, of the spectrum.
df specifies the frequency resolution, in hertz, of the spectrum.
complex spectrum specifies the complex form of the computed spectrum.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
spectrum data returns the spectrum converted into a class. The class contains the spectrum and spectrum info. The class enables header information to appear on the cursor table of the Spectrum with Cursors XControl.
error out contains error information. This output provides standard error out functionality.
