I was thinking more along the lines of an analog buffer, but you make a
good point. And if I want a sine wave output, I could use a simple pi
filter to clean it up. I have an HP 8647A RF generator that does
exactly that on the 10 MHz reference output.
Thanks!

Ed,
I have seen a hex schmitt trigger inverter used for this.
The output of the OXCO goes into all 6 schmitt rigger inverter inputs and then
on the output side you have the output leg of each inverter connected through
300 ohm resistance. Thusly you get 6 hex schmitt trigger inverters wired in
parallel and with a combined output resistance of 50 ohms.
Very simple and might be just the thing you're looking for.

Subject: [time-nuts] HP 105B Modification
I have a late-model 105B Oscillator that's equipped with a 10811-60109
oscillator. It seems a shame to have that nice 10 MHz source without
having access to it. I was thinking of adding a buffer amp and bringing
out the 10 MHz signal. It shouldn't be too hard, but before I reinvent
the wheel, has anyone done this and do you have any suggestions or advice?
Thanks,
Ed
