Btw, these 30wfms/s, yes, on "the slowest DSO ever" (no, it's not, LeCroy, TEK have some similar "gears") they need to
be watched from a different point of view:
- let's take a Rigol DS2000, at 14000points we have max 50k wfms/s. Divide now these continues 10M points / Rigol 14k,
that's 714 times more, so divide now Rigols 50k wfms/s / 714 and we get 70. That's means Rigol's "equivalent" wfms/s
(to get total of 10Mpoint sampled data at one piece) is 70 wfms/s, this is not that much compared to Owon's 30 wfms/s.
- let's take Agilent DSOX3000, at ~2000point we have 1M wfms/s. Now Owon 10M / Agilent 2k ist 5000, and then
Agilent 1M wfms div by 5000 is 200. So the DSOX3000 "equivalent" wfms/s is at 200, this is only 7 times faster
than Owon (and not like 1M wfms/s vs. 30 wfms/s).
I remember LeCory used this as sales argumetation "the data is there, you have only to search for it", and that's the crap
here, the PC software is crap, all you can do is to export to csv and search with 3rd app to find a glitch. So the "idea" behind
what Owon did was maybe good (or at least something what other did as well when faster wfms/s at small buffer was
not possible to get implemented), but due missing inteligent zoom or/and search and/or PC software the implementation is bad.
I however prefer to have small piece of data updated very fast, when impemented properly (DPO-like) the benefit (save of time
while watching/searching loooong records) is huge.
Where Owon made for sure a mistake is the wfms/s at 1k/10k, if they were at 1k let say 1000 wfms/s, everybody
would be happy (or at least not complained about).
Anyone want a bargain?
There's only one at this price and you've seen it in the review. We tested its bandwidth and it met spec.
As others have said, if all you want is sample rate, bandwidth and 10M memory, then its not bad at all at the advertised price.
that's exact the point (and i don't like Owon, never ever liked), bandwidth is good (and can be for sure changed up to 500MHz), sample rate high enought for 1GHz DSO (even if "only" with 100k, but that's more than enought) and 10Mpoint are a lot
of memory, yes with 1GS/s max, but that's fair enought. And when someone really need to find a glitch, hell, then export
the data and use Excel to search. For that price there is no competition for SDS9302.
