Great work, John!!! I'm really looking forward to the actual SDR-1000 measurements to see whether the noise multiplication from the on-chip multiplier is according to theory or if there are other factors involved beyond simple scaling. I haven't had a chance yet, but will also compare your measur

Hello Enthusiasts, I've made several phase noise measurements and posted them at www.exothink.com/SDR. The first page shows plots comparing different quality oscillators suitable for use in the SDR1000. The second page contains several measurements at the DDS output. These graphs were generate
