Hello Anders,

Yes, I explicitly cite IEEE1139-2008 table B.2 in my thesis. I will
write a more detailed reply with example data later when I get home.
If you would like to try out the noise
Hello Mike,
Thank you for sharing. I would like a copy of your Thesis when it published (I
don't need a physical copy, .pdf is ok). I'm sure others out here would like
to see it as well.
I'll post an update once it is published, which is hopefully soon :)
The thesis will then be available as
1588-2008,
2016, Vienna University of Technology
As of this writing (April 2016), it is not yet published, the expected
publication date will be May or June 2016.
I hope these projects can be useful for some of you :)
In case you have any questions, feel free to ask.
Kind regards,
Wolfgang
Hello time-nuts community,
thanks to your feedback and that of others, I could make additional
progress on my journey to understand powerlaw noise :)
I would like to reiterate what I have learned so far. Please comment on
anything that you think is done wrong.
for the Random Walk phase noise.
Cheers,
Magnus

What kernel do you use? And what scheduling configuration?
As it is a timing application, and sensible to jitter, I would suggest
to use a real-time kernel (e.g. Preempt RT) [1].
Usually one can find pre-built kernels with PreempRT-support for boards
like the RPi etc. on the internet.

Hello Tom, hello time-nuts,
Have a look at the 20 plots in:

Thanks for sharing the data and the PDF! It's good to have reference values.
I also had a look at the stable32 user manual [1] to see how it
calculates the PSD

Hello,
thanks a lot for all your feedback (also in the other threads)!
It will take some time to read reed through all your recommendations :)
