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.
Regards
Nigel

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.
Bob
