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.
