Thanks for the thought, but that device doesn't hit either the frequency range or the phase noise requirements we're looking for.
The VCO on that part has a 10k SSB phase noise of -89dBC at 2.2GHz that's worlds and worlds away from the -120 I'm on the hunt for.
To clarify what I'm trying to do a little I'll give some more detail.
Currently our PXI-5663
has pretty good phase noise performance by taking advantage of the PXI-5652
. The 5663 is actually 3 different PXI modules cabled together (LO PXI-5662, Downconverter PXI-5601, IF Digitizer PXI-5622).
Because of it's modular nature, we can substitute our LO with a different LO with even better phase noise performance when the measurements call for it. Just one of those 'Damn, that's sweet!' kind of capabilities you get with a Modular Instrument approach to RF test.
