Re: How limitting do you think a scope would be if it were limitted to 35 volts?

Is it 50 million samples per second or something like that?

Yes.

That's the number of measurement points this thing takes. To properly picture a signal you need many points along it, if there aren't enough the shape will not be correct.
The 1Gs periodic thing is for repetitive signals. If you imagine a sine the scope takes say 10 points from one period, and then 10 from the next, but slightly shifted in time, and 10 from the next, again slightly shifted. In the end it puts them all together to display the one single sine. But what you really get is images from several periods. The signal better had the same shape in all periods or it won't make any sense. Of course with something that isn't repetitive the scope can't take data from the next period to throw it all together, it has to sample "real time", and that it can only do at 50M points a second.
