analyzing those fewer dots may reveals whether the scope showing sampled data only, or sampled data along with interpolated data, like Lecroy snapshot is combination of vector and dots, but the dots are interpolated data.

Want some special screenshot ?Just ask.

it will not hurt to post related stuffs. if you can plot as close as possible as Lecroy capture (vector + dots) or dots only maybe can add value to the thread or the "marketing" ;) but for me, data gathered are already adequate, and my points are conveyed hopefully. cheers.

Dots are the raw sampling points, nothing else. This I can prove.
One complete period from the 10 Mhz Bodnar enough ?

Mechatrommer:
it will not hurt to prove, but i trust you already. this is basic stuff which everyone already know. please do so if its not too much hassle for you (i hate asking people to do more than what i need) cheers.

tautech:
A selection, mostly dots but some vectors when we need compare.
Toggled captures between Dot and Vector mode.
Most in Stop mode but a few running, all easy to identify.
Any in Stop mode are also toggled between Dot and Vector mode.
Max at 200ps/div. Dot count in the Timebase tab.
All in Auto memory management mode.

Please stop this BS about dot interpolation.

Substrates that can predict the future?  :)
