For anyone interested in an introductory class on phase noise, I'm teaching an online class with live instruction (with video recordings in case you miss a class) titled "Phase Noise Fundamentals." https://www.jitterlabs.com/support/training Register with the coupon code TIMENUTS1704 to receive 10% off (which can also be applied to our online jitter course). The coupon expires at the end of April 2017. Aside from that, I thought I'd share some general-interest phase-noise articles I published recently: "Determine the dominant source of phase noise, by inspection: A simple 3-step procedure that anyone can apply when viewing a phase noise plot" https://www.jitterlabs.com/support/publications/note4/note4 "Measuring phase noise with baluns" https://www.signalintegrityjournal.com/articles/207-measuring-phase-noise-with-baluns http://www.microwavejournal.com/articles/27224-measuring-phase-noise-with-baluns If any questions, please contact me off list.
