Hello to the group, Have you ever used frequency/phase data to estimate phase noise of your O's using Stable32? I probably do something wrong in conversions when using Power button because my plot starts on 10e-7 Hz and ends on 10e0 Hz

For AllanTools and other testing I have tried the FFT plots in Stable32. It seems to use a fairly simple FFT which has problems for divergent noise-types. The Welch algorithm is better for these. The x-axis should end at the Nyquist frequency, i.e. half of your data rate. For meaningful phase-noise analysis you'd want phase observations at 100 kHz or more, e.g. from an SDR or similar.
