The TSC5120A allows phase noise measurements on signals with

Classical diode mixer based systems can go somewhat lower in frequency.
You should realize that I have reasons to believe that the limit is
one of software parameters rather than anything else.
Lacking a TSC5120A or sufficiently similar in my lab...
I'll use a 5120A for 10M to 5M or 2.5M or 1M cases.
Mostly 10 MHz and 5 MHz sources would be tested.
Below that I'm in the same situation as you, with the usual
lab assortment of HP, SRS, Wavecrest, and Pendulum TI
counters. I have logging for all of them; except Wavecrest
but Said has experience with that noisy beast and is already
helping me out (Thanks!).
I would be interested in whatever you come up with. My logging is at the
unacceptable level. The Pendulum I can log with their software.
A partial GPIB-network spans the backside of the workbench, but it needs
rewiring and more wires.
My preferred platform is however Linux and in particular Debian. Just to
keep things a bit interesting.
Cheers,
Magnus
