Ever heard of Nyquist? Plus to see anything like a signal for your eye's benefit, you're better off with x10 sampling. So 100MHz is more on the mark. Does it allow you to simply plot the points without the "join the dots"? BTW if you had exactly 1GHz going in, and it manged to sneak pass the front end, you'd end up with a straight line at some DC level. Ray
