same here, I would encode the default of 256 so that it can not get out of sync with the down stream functions.

warnings.warn("Only one segment is calculated since parameter NFFT " +
"(=%d) >= signal length (=%d)." % (NFFT, len(x)))

spec, freqs, t = _spectral_helper(x=x, y=None, NFFT=NFFT, Fs=Fs,
detrend_func=detrend, window=window,
