Putting 50Mpts or more of sample memory in a measly 2GSa/s scope is silly and only serves marketing purposes.
Equivelent is that perhaps then 25M for 1GSa/s scope?
Indeed.
Silly perhaps but do this in attached image even with this 1GSa/s samplerate using less memory or example with this R&S. Just, no way - end of game. What next, job is still waiting to do.
Not really. You may not be able to do a 40000x zoom into a signal but that doesn't mean ther's no other way to get the same result (I'm not even sure why you want to do that in the example you gave, aside from just showing off that you can).
Silly, is it. Only for marketing? Do you really think that if you do not need something it is true for all others who of course are wrong because you know what is silly and what is not.
Well, we're talking about general purpose low end scopes that are mostly bought by hobbyists, and I'd bet that the percentage that would truly benefit from >50Mpts sample memory on a slow 2Gsa/s scope (or even >25Mpts on a measly 1GSa/s) is miniscule.
Of course if you wanted to use a scope as long-term recorder then there's use for lots of memory, but these are mostly industrial applications for which only few would touch a B-brand like OWON anyways (and rather use something more appropriate like a Yokogawa ScopeCorder).
I'm not against offering large sample memory, but do believe it's silly to put excessive amounts of memory in a slow bottom-of-the-barrel scope and then not even offering a proper search functionality.
Is this something what is not normal oscilloscope use. If it is not normal use, define what is normal use I do this kind of things many times.
(it was ultra simply crap cycle-cycle jitter (or something like it) check for 10ms period 20ns pulses with also infinite persistence running long time).
Many times I miss lot of more memory just for keep full samplerate with low timebases. Other way is segmented acquisition.
This seems to be more down to your personal preference than a real requirement for that measurement. You don't need excessive sample memory to measure that.
How about you show us some examples of problems which really *require* say more than 20Mpts on a 1GSa/s scope and which would not be possible on a similar scope with say 2Mpts or 4Mpts?
