FFT to Spectrum VI
Owning Palette: Scaling VIs
Requires: FPGA Interface
Converts the output of the Fast Fourier Transform (FFT) Express VI to an amplitude or power spectrum.
 |
real FFT data specifies the real data to convert to the spectrum. | ||||
|
imaginary FFT data specifies the imaginary data to convert to the spectrum. | ||||
 |
spectrum type specifies whether the output spectrum is an amplitude or power spectrum. The default is Power (Vrms^2).
|
||||
 |
sample rate (S/s) specifies the sampling rate, in samples per second, for the FFT. Use the actual sample rate (S/s) output from the Sample Rate To Loop Time VI to obtain the sampling rate. | ||||
 |
error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality. | ||||
 |
spectrum out contains the power or amplitude spectrum depending on spectrum type. | ||||
 |
df (Hz) returns the frequency resolution of the spectrum in hertz. | ||||
 |
error out contains error information. This output provides standard error out functionality. |
