I asked Wenzel about mixers for phase noise measurement and they directed me
to Marki Microwave as what they use:

tested any myself but it's a pretty solid recommendation I think.
I got this guy to add cross correlation to his FFT software suite:

has a 30 day trial and its not expensive for what it is, $300.
There's no evidence of a cross power spectrum function in this suite.
One needs to be able to average at least 10,000 cross power spectra for
some applications.
