SainSmart DDS120 & DDS140 USB Oscilloscope

Hi all.

I am writing this to notice that DDS120 source code is available, by disassembling DDS120.exe or BM102.exe with ".NET Reflector". Other disassembler may also work.

This operation will produce c# sources out of DDS120.exe. Produced solution/project can be opened and edited on Visual Studio 2015,  older versions of VS may work also.
Of course program logic can be seen on  .cs sourcefiles with any text editor, so installing Visual Studio is not obligatory if just inspecting inner workings of device.

I don't know if this kind of disassemly for interoperatility/compatibility is legal in every country. Check legal things before using this method.
Hopefully at least someone can make use of this method, and produce finally a working scope software for DDS120.

Cool story mate. Will look into this.

Seems like someone did some efforts in the DDS120 application, found somewhere on the net...

This that are fixed:

- Translation
- 50/48Mhz correction
- interface speedup and datatransfer optimization (much faster now)
- adjustements to buffer sizes to improve triggering
- faster buffer scroll
- removed "useless" timebase settings > 200ms to avoid overflowing data buffer (maybe readded in the future if the data acquisition is rewritten/adapted)
- antialiasing to graphs + "digital Phosphor§
- other stuff

Works good for me.

I am new on this forum and the world of USB DSO's.
Still deciding between the SainSmart DDS120 and Hantek 6022BE. (Any suggestions, which one is the better?)

A new software version for the DDS120 is mentioned in the previous post as Link 1.2.1 , but the link is dead. Any chance to repost that file please?
Or, what is the difference between the 1.2.0 and 1.2.1  ?

Gyro:
IF you're really looking for a low end USB scope, as opposed to the Rigol standalone one that everyone here recommends, then I'd suggest the Owon VDS1022 in preference to either of these, it's way ahead of them in performance. There are a bunch of these on ebay from China at the moment for not much more money:
