Window Type
The type of smoothing window to apply to each data window.
FFT Length
The length of the internal buffer used to compute the power spectrum, in seconds. A greater FFT length results in more data points in the output spectrum (for greater resolution).
Window Length
Specifies the length of a single window of data.
Window Overlap
The overlap of subsequent windows.
Windowing Units
Sets if the window length and overlap are specified in points (samples) or seconds.
Zero Pad Data
If checked, the data is zero-padded so the first window is centered at the start of the original data series and the data series divides into a whole number of windows.
Remove Offset
Before computing the power spectrum, the mean is subtracted from the signal.
Output Units
Specifies if the spectrum should be represented in linear scale or in decibels (logarithmic scale).
