Have successfully tapped into the clean 10 MHz of the the Lucent and using a EL2020 50 Mhz current opamp have a very nice 10 Mhz sine wave out. Any spurs are down at least 43 db. Close in at 4Khz total span or 500 Hz/div I don't see anything down to at least 65 db. Thats the best detail the HP 8568B will allow.
To get the signal out of the Lucent I sliced the 15 Mhz trace and injected the 10 Mhz into the SMA output connector. I am sure there are many other amplifiers and methods that could be used but this ones working well and can drive some real coax lengths. Now the really hard part. Mounting it and the power supply into a rack panel.
