OK, I'll be crossing that one off the home lab wish list!

At this point, just the detailed 35601a system block diagram
showing the switched signal paths and gain/filter settings
should be enough for me to figure out how practical building
a Franken-3048a would be.
Don't spend time scanning the manual on my account, I'll
order a hardcopy from Manuals Plus once I sort out why they
have two different P/Ns listed for the service manual.

The later discussions of homebrew PN setups may have
obscured my original question:
Has anyone ever looked into the feasibility
of using a 35601a as a stand-in for the 11848a
in a 3048a phase noise system?
I have a 9000/340 computer with the 3048a software,
a 35601a, and can probably pick up the 3561A narrowband
analyzer needed by the 3048a software for $300-500 USD
(with some patience).
The 11848a's usually still have four digit price tags.

Yes, I plan to have two (or three) copies of the LO/reference chain
in question, and pull one of the OCXO's for quadrature lock.
thanks,
