Owon 12and 14 bit scopes vs. new Rigol and Siglent lines?
maxwell3e10:
I am probably one of the few here who had been consistently speaking up for Owon scopes and using them for nearly a decade. XDS3062A first appeared in 2015, https://www.eevblog.com/forum/testgear/new-owon-xds-oscilloscopes. They had a lot of features (12 bit, built-in battery, largish touchscreen, internal generator, bode) at that time which are only now becoming common in low-cost scopes. Regarding hardware performance, here is a direct comparison of Owon XDS3062A and Rigol HDO1074: https://www.eevblog.com/forum/testgear/rigol-hdo1000-and-hdo4000-12bit-oscilloscopes-launched-in-china/msg4999327/#msg4999327. Owon actually has better dynamic range and can resolve, for example, phase noise of HP3326 generator, while Rigol cannot. I haven't actually tested a 14-bit version of Owon, so can't say if it offers higher dynamic range compared with 12 bit.
In general Owon has some drawbacks and occasional glitches, but I think lack of popularity here is just because it is not hackable.
If I had to buy a cheap scope now, I would probably go for Rigol or Siglent because they will have more updates and hacks, but I am not rushing to replace my home XDS3062A. On the other hand, at work Rigol DHO4000 is sitting on a shelf, having been replaced by an older generation Yokogawa. One problem with new HD Rigols is that they use screen memory of 1000 points for a lot of data processing, not the full (what they call deep) memory. So when saving data from it there is a lot of confusion what has been done with it. Other problems are poor overload recovery, weird screen Moiré patterns, no PC interface software.

ok, what I get from those measurements is that the Owon is signficantly better in wide band noise, not so good with 1/f noise and has spikes all over the spectrum. I don't even think these are nonlinearities as they pop up in the noise measurement as well.
BillyO:
Not that anyone cares, but Hanmatek and Owon are both made by a company called Liliput.
Low end Owons are also available as Hanmateks. They even look identical. :-//
TomKatt:
Owon / Hantek = Hyundia / Kia
Rigol / Siglent = Honda / Toyota
In fairness, I've got a portable battery operated single channel 20MHz Owon HDS1021M scope that I bought around 2008 and it still works well for what it is. It was the absolute cheapest portable scope I could find at the time. It pretends to have multimeter capabilities but you'd be foolish to use them. But for verifying a basic presence of a signal it works fine. Battery also allows for floating measurements, which although potentially unsafe is certainly very handy.
