Has anyone hacked or cracked OWON XDS series?

Plasmateur:
I'm considering to purchase an OWON just for the higher bit resolutions - for a dedicated application I have in mind.

I want the functionality of a XDS3204AE and was wondering what base model I could purchase in order to crack it up to this model. Searching on the internet I haven't found too much information on this.

Link to scopes - https://www.owon.com.hk/products_owon_xds3000-e_series_4ch_8_|_14bit_touchscreen_digital_oscilloscope

Also, searching EEVBlogs I see a few threads and discussion about OWON scopes, but not nearly the amount that are found on Rigol or Siglent. Overall the sentiment seems pretty negative. I've also watched both of Dave's videos on the XDS3202A and he stated that scope wasn't all that bad, but it wasn't good either.

So from all of this, I figured, if I can get a base model like the XDS3064E and crack it up to a XDS3204AE, I wouldn't mind spending sub $500 on a scope like this. With that said, has anyone hacked this? If not, any suggestions on how I go about getting started on doing that myself?

I have a few XDS scopes and generally like them. They are not without problems, but it's nice to have high vertical resolution, larger memory and larger screen than a basic scope.  Higher bandwidth doesn't make that much sense since 12 bit is limited at 500 MHz sample rate for one channel. So XDS3064AE and XDS3062A are mostly sufficient and they do have a little larger bandwidth than spec. There is also a cheaper XDS2102A model. One can also get relatively inexpensively touchscreen, build-in function generator and internal battery options. So, it's a cheap version of "high-end" scope.

I am not aware of hacking attempts and to what extend the hardware already exists in lower models.

I don't think anyone hacked a Owon XDS scope. That been said this guy (http://blog.weinigel.se/2016/05/01/sds7102-hacking.html) did a lot of reverse engineering on a older model (SDS7102). I guess the XDS series share a lot similarities.

Is this actually using true 12 bit ADC? If so, do you know what ADC? Does the vertical channel chain hold-up to the 12 bit resolution? Asking since we are considering this as the Siglent 6000 will not be offered in NA, and the LeCroy is quite expensive for us, we are on a limited budget.

Thanks for any help.

Best,

There is discussion of ADCs in the EEVblog review. 12/14 bit models use HMCAD1520, I suspect 8 bit model uses HMCAD1511. I posted some data on the noise of XDS3062A here at one point.
