[time-nuts] Examples of traditional phase noise analyzers

[Mike Feher]

Back in the late 80's we were making phase noise measurements by analog
means at 44 GHz. Regards - Mike

Subject: [time-nuts] Examples of traditional phase noise analyzers

Good afternoon,

In the process of writing my thesis I stumbled over the problem that the
definition of what phase noise is in IEEE 1139 is a bit confusing, to put it
mildly. After a short discussion with Magnus, it seems clear to me that I
need to have a better understanding of how phase noise measurement was done
in the past to properly understand what the standard means to say.

I think, I have a decent grasp on how modern phase noise analyzer work, safe
for a few details here and there, where they seem to try to mimic what the
old analog analyzers did.

Before I go on a wild goose chace, I thought I ask here for
advice: Could you point me at as detailed as possible descriptions on how
phase noise analyzers used to work in the purely analog times? Preferably
also as many different approaches as possible.
And, if you are aware of anything that I should have a look at that might
not be obvious to a youngster like me, I would very much appreciate if you
would let me know.

Thanks in advance
