Weird behaviour of the analog signal source (was: Re: How ensure consistency with timing signals)

Hi Marcus, How can (or better: *should*) a fully digital signal source have phase noise? Also, for 1Hz at 5MSps I always get either 5005789 or 5005790 samples (instead of 500) ... this is fairly deterministic. Experimenting a bit, I see the weirdest behaviour of the analog signal source. In
