so you did single shot, zoomed out and the visible record length is 10ms when in single chan mode and 2 x 20ms when both chans enabled ?
@tinhead - Yes, that's exactly what I did. But let me tell you, the 10Mpts of memory, just like the gorgeous display, is another example of nice hardware - which is not taken full advantage of by the software. When you are 'zoomed in' on a large record (small s/div), the encoder knob still moves you horizontally at the same speed through the record as always - it takes forever to move around it - and it's easy as pie to get lost. Why not, for example, if the scope is stopped and you're just browsing the data, have the encoder movement different and faster for zooming and jumping through the long record - as well as change the display feedback to better locate your position? Also, the Owon PC software is crap, so trying to look at these long records there is tedious - but that I could rewrite, so it's not such a problem.
If so, then that's an overkill for many other DSOs.
Sure, for most things, but if you need to log data over time, it can be a godsend.
Curious on the Owon sine at 100 MHz. On the Rigol, now using mechatrommer's software, the reduced data points does show in the interpolation as a distorted sine
@saturation - yes, the 3X25 only uses 2 points to represent a 100MHz sine wave so it's actually more like a perfect triangle wave. But since I can't switch off sin(x) on the Owon, there's no way for me to see the actual data points it is sampling (it always shows the interpolation) unless I save the waveform and take it somewhere else to look at it. I wish I had a high quality function generator to really test this scope with.
I tell you, this has to be the most frustrating thing I've purchased lately - leaving aside the unknown electronics for the moment - except for the stiff membrane switches and the slightly cheap-feeling smaller encoder knobs - the design, ergonomics, and hardware (at least on the outside) are attractive and very appealing. Who owns a cheap Chinese DSO but doesn't want a thinner desktop model, or an 8" 800x600 screen, or an optional 4 hour lithium battery, or a whisper quiet fan, or a smarter trigger pass output, or VGA output (it's great to see the waveforms really huge from a distance away when probing), or 10Mpts of memory? You can't use this Owon and not feel that this is the direction many of the Chinese DSO makers will be moving in the future. But the firmware is discouraging and there is so much untapped potential.
I have to decide tomorrow (or Friday morning at the latest) if I will keep the Owon or return it and go for the Hantek. It would be kind of a shame to relinquish the flash new hardware, but I can see by all I've read that the Hantek firmware is better (and the electronics are proven) - and even though I would end up with a DSO without as many initial bells and whistles, I'd have one which is less frustrating and probably more useful in the long term.
