Yes, because the XCVR2450 is highly integrated, its phase noise will not
be as good as the RFX2400. I don't think it is quite 20dB worse, but
maybe 10-15 dB.

I've had quite a few problems which I think are caused by poor phase
noise on the XCVR2450 -- it's an all in one chip with a local oscillator
on board etc - the 2400 appears quite a bit better (20dB if I remember
correctly!)
The schematics are in an odd place for this board - I could only find a
link under the USRP1 page

Dear All,
I would like to learn the noise floor of a receiver which uses USRP,
XCVR2450 and VERT2450.
Namely, when usrp_fft.py is run with no incoming signal present in
an indoor environment, what is the expected noise level?
Thanks in advance.
