    I have been loving this software for long time. I just have two little requests. I really wish you guys can look into it.
    In the rta section.
    1, include increased fft length for option this will help the noise floor.
    2, include max overlap of 0% for option as this will as well help with the boise floor.
    Thank you so much for developing such wonderful software.

    Longer FFTs can be added, how long were you looking for? Don't see how the overlap affects the noise floor.

    Thanks for the fast reply!
    About the fft length, maybe a few times longer, perhaps 1M.
    About the overlap, as I increase the percentage of overlap, the noise floor on the graph apears higher, so I think changing to a lower value can give a lower noise floor.

    Overlap shouldn't affect the noise floor. What kind of signals are you measuring and with what window and averaging? If there was no overlap sections of the data in the tapered region of the window would only make a partial contribution to the result.

    Ok. I just tested with different averaging option. The higher noise floor is caused by the fixed averages which was 32 when I tested before. My bad.
    I use hanning window all the time with 32 averages.
    And I mainly test pure sine waves for my amplifier.
