Another thought , I have done this with a pair of synth sig gens:
The brik's designs are such that you can typically get them to phase lock at
harmonics of 100 MHz around the nominal. So you should be able to get one
to phase lock at 10.1 or 9.9 GHz, giving you a 100 MHz offset beat note from
For close in phase noise, the kind that is usually of interest, and hardest

No 10 MHz out and very low 12 VDC current.
Has anyone the translation from HP PN to Commercial equiv for the

Thanks
