Hi Bob, Thanks for that, I wasn't expecting too much from the 10MHz, thinking of it as probably a quick and dirty reference for portable test gear, but maybe wasn't expecting it to be quite that bad either:-) 15MHz I would have expected to be reasonable, and my goal is still to extract 5 MHz directly from the oscillator, buffered as necessary but with as little degradation as possible, but for now I've had to content myself with live monitoring of the plots on a couple of Pendulum counters, what with all being as chaotic as usual round here and far too much test gear stacked up in piles and nowhere near the bench:-) You've whetted my appetite though so will try and stretch some cables later and take a closer look at the outputs.

Hi I got a chance to look at phase noise today. I’ll try to post the plots later. Quick summary: 10 MHz - ugly. Lots of spurs, many of them close in. Poor phase noise floor. 15 MHz - pretty good. Noise floor is not as good as a TBolt (by 5 to 15 db). Far fewer spurs than the 10 MHz, fewer spurs than the TBolts I’ve looked at. ADEV on a short run looks better than an un-tuned TBolt. I’ll need a much longer run to see what it’s really doing.
