I guess what I'm saying is if one is going to the effort to build a
DA from scratch, why build something that is just adequate to
distribute a reference signal to test equipment and radios? Why not
really do it right, and build something that *is* capable of
buffering and isolating signals for serious phase noise and ADEV analysis?
