Among your many choices:
SignalHound SA-44B919 USD (0C - 70C version)

With its (free) SPIKE software, you can measure phase noise (and much more).

Hi
The cheapest approach for phase noise is probably to use a single RPD-1 mixer
plus preamp and feed the
output into a sound card. Total cost should be under $100. Yes, it’s a DIY sort
of project rather than a “buy
it and use it” sort of thing.

Kind of an open ended question, but here goes ...
Hi,
There is actually more approaches. Me and NIST showed you can setup a
cross-correlating interferometer, it actually works, but is so far hard
to maintain properties, but the principle works so we presented and
published it.
Another approach suggested by Enrico is to actually compensate with
That should have been:
Its only necessary (as NIST have shown) to cool the splitters to reduce the
correlated or anti-correlated thermal noise between splitter outputs.
Everything else can run at ambient temperature.

That's quite an impressive system. I guess it's a few generations beyond
my 11729C.
One way to get overall performance to the limits of room temperature kT
noise level, is to lower the T where you work. I wouldn't be surprised
if some parts are TE-cooled, easily affordable in a big budget

The thought of what it must cost is frightening. A colleague just acquired
a *used* 5503 for a bit under $50K.

This seems quite an impressive bit of kit, which in the standard
