Rick,
I think this was the comment I was referring to:
https://lists.febo.com/empathy/thread/
Which says:
"... the phase noise is not as good as a
10811 due to broadband noise in the automatic frequency
control circuit. By the time I discovered this, it
was too late to try to fix it."
And after nine years I obviously somewhat mis- remembered it. But I still
wonder whether you had any ideas to improve it.
Cheers!

I'm sure I said that ... a long time ago. I can't remember now what the
fix was, but I am fairly sure it would only apply to phase noise at
more than 1 kHz offset. If anyone can jog my memory about it I might
be able to remember the details.

Rick Karlquist mentioned some time ago that the phase noise of the E1938A
could have been improved by a simple change, but the production managers
were unwilling to apply that change because there was no customer demand
for it.
What was that change, and is it feasible for a skilled hobbyist to make
that change on an individual existing unit or two?
Cheers!
