Actually I have a pretty keen sense of humor... when I see it. Besides, you criticized him for his grammar and yours is *always* atrocious, not to mention your spelling.

I don't think I understand the sinc thing. What should I expect to see from it?
The AD9854 has an inverse sinc filter, from p30 of the data sheet:
"Both DACs are preceded by inverse sin(x)/x filters (also called inverse sinc filters) that precompensate for DAC output amplitude variations over frequency to achieve flat amplitude response from dc to Nyquist."
It uses a whole watt, so has a separate power-down control.

Never mind, I found an explanation here: It doesn't explain my problem, but that's ok.
