Hi Marcus,Interesting discussion. I was wondering how well synchronized clocking might work. Was hoping it would work better than it sounds. Could you quantify the level of phase noise you're seeing, like with a power spectral density plot? Just for curiosity's sake?I know of a recently updated OOT module that should have the blocks you need ;-)I was hoping to build a correlating interferometer by modifying several of these dongles to run off the same clock. I may need to rethink the plan.Jared
I'll get to that tomorrow night.I just ran a simulation of what I was observing (just because the lab is downstairs, and I'm upstairs).
Looks like the best it does is about -40dB/c 75kHz from the carrier. That's bluddy awful.
