I was planning to assemble generator to test amplifiers using AD9851. But while I was waiting for packages I just bought another cheap generator which is enough for my purposes. I was planing to use AD9851 with RD16 amplifier and control amplitude with ALC signal. Now I’ve just assembled it and tested for fun using this article — Arduino based DDS Signal generator using AD9851 — Hackster.io with little changes as I have different display.
50MHz pretty big jitter:
Lower frequencies more acceptable (from 30Mhz):
