Owning Palette: Baseband FFT VIs
Use the Baseband Subset VIs to compute subsets of the baseband FFT measurements.
The VIs on this palette can return ranges of LabVIEW error codes or specific sound and vibration error codes.
| Palette Object | Description |
|---|---|
| SVFA Coherent Output Power Subset | Computes a subset of the coherent output power based on scaled signal X [EUx] and scaled signal Y [EUy]. The subset is defined by frequency range. |
| SVFA Cross Spectrum Subset (Mag-Phase) | Computes a subset of the cross power spectrum of scaled signal X [EUx] and scaled signal Y [EUy]. The subset is defined by frequency range. Results are returned as magnitude [dB EUx EUy] and phase [dB EUx EUy]. |
| SVFA Cross Spectrum Subset (Real-Im) | Computes a subset of the cross power spectrum of scaled signal X [EUx] and scaled signal Y [EUy]. The subset is defined by frequency range. Results are returned as real part [EUx EUy rms] and imaginary part [EUx EUy rms]. |
| SVFA FFT Spectrum Subset (Mag-Phase) | Computes a subset of the FFT spectrum of scaled signal [EU]. The subset is defined by frequency range. FFT results are returned as magnitude [dB EU] and phase [degrees]. Each block of data corresponds to a single FFT block and has to be passed individually to this VI. You can use this polymorphic VI to analyze signals from a single channel or from N channels. The data type you wire to the scaled signal [EU] input determines the polymorphic instance to use. |

| SVFA Frequency Response Subset (Mag-Phase) | Computes a subset of the frequency response and of the coherence based on stimulus signal X [EUx] and response signal Y [EUy]. The subset is defined by frequency range. Results are returned in coherence, magnitude [dB EUy/EUx], and phase [degrees]. |
| SVFA Frequency Response Subset (Real-Im) | Computes a subset of the frequency response and of the coherence based on stimulus signal X [EUx] and response signal Y [EUy]. The subset is defined by frequency range. Results are returned in coherence, real part [EUy/EUx rms], and imaginary part [EUy/EUx rms]. |
| SVFA Power Spectral Density Subset | Computes a subset of the power spectral density of scaled signal [EU]. The subset is defined by frequency range. Each block of data corresponds to a single FFT block and has to be passed individually to this VI. You can use this polymorphic VI to analyze signals from a single channel or from N channels.
