A project log for GHz Signal Generator

A flexible signal generator based on the AD9914 DDS chip. Striving for lab-quality noise figures and supreme flexibility.

As I near the capture/layout phase of the DDS section of this project, I'd appreciate any feedback and/or usecases anyone can provide. For example, is it more useful (for you) to have an ultra low-noise signal < say 100MHz, or would you prefer to maximize the modulation capabilities of the DDS? I'm toying with some ideas on switchable output filters, as well as trying to get an idea of down the road, what kind of processing power the daughtercard should exhibit...

Thanks and hack on!
