SainSmart DDS120 & DDS140 USB Oscilloscope

[doctormord]

Hi guys! And among those specifically doctormord, psynapse, ganzuul and donut6!
Great thanks for what you've done and even more have shared here. Inspired by this thread I've created by own version of desktop client for DDS140 Logic Analyzer module.

Great work,

would you mind to implement support for the DDS120?

USBEE AX clones are available, DDS120 is just a variant of this, they are all variants of the Cypress dev boards.

Is Picoscope also variant of Cypress FX2 board ?

Yes some models are: http://sigrok.org/wiki/Oscilloscope_comparison

Well, they aren't as they just use the FX2LP interface but rely on custom FPGA implementations.

This thread doesn't seem to have been active for 2 months, which is a shame, but makes me extra hopeful there has been some progress. So does anyone have a good working software yet?

I tried Ledioskope, which looks good, but that doesn't seem to have a trigger. And the official software is pretty crappy of course, so I won't even mention that.

When I purchased it, it looked so good. But now I actually have it, I'm kinda dissapointed

I had the same issue with DDS120 Oscilloscope Windows 7 64 bit. "Device not found"
Delete any previously installed Oscilloscope driver from device manager.
Right Click "My Computer" -> "Manage" -> "Device Manager" -> "Action" -> "Install Legacy Software" -> "Have Disk"

First I installed the Win7 XP Driver which didn't function properly.
Next I updated the driver to the Win7 64 bit version.


Ran Application....and device connected properly.

Hi all, SainSmart now sells a cheap Hardware Trigger Module for the DDS-140:

http://www.sainsmart.com/sainsmart-hardware-trigger-module-for-dds-140.html

people in this thread have been complaining about the lack of a hardware trigger for the DDS-140,
does this device make it more useful?

Any chance that we could get this hardware trigger to be supported by the various software projects
that have appeared in this thread?

Hi all,

I read this thread but am still confused on how to install and run this on a windows pc, can someone please help?

I downloaded OpenHantek 0.2.0 but none of the files have extensions, i.e. install.exe, just install

Thanks

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. 

[doctormord]

Cool story mate. Will look into this.

[doctormord]

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  ?

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:

Here's the teardown thread:

[jdev99]

Thank you for that info and the teardown info you and Mark_O provided.
The Owon is for sure the winner here, nice Xmas present from myself to myself.

[Gyro]

If you hurry. Santa may smile on you! 

[doctormord]

Is the software any better?

[Gyro]

What? The Owon vs the other two?

Yes, by miles. Mark_O commented on that (at least against the Hantek) in the teardown thread. I showed screenshots and shortcuts in the same thread.

Has anyone found a driver for the DDS120 that will work with Windows 10?  Win7 driver with Win10 unsigned driver install does not work.  Standard Win10 driver install does not work.
      ..Rock..

[doctormord]

From Win8+ there isn't any driver needed - that's what they claim.

your version 1.3.1 doesn't work for me. Currently I am using Windows 10 and version 1.3.0 works fine.
meantime, I have created C# code from DDS120.EXE using ILSpy (from icsharpcode), but compiling back doesn't work (so many warnings). any advice is welcome!

[lmorgan3d]

Thanks for the reply doctormord, followed the Amazon link, looks like two got it to work, and one didn't.   No details on the install. 

I would imagine it should install like Win8...  but I tried with and without the unsigned driver procedure for Win10, it doesn't not install.  In reviewing the sources that sell the DDS120, none of the sites state Win10 compatible.   I have not been able to locate the original DDS120/140 vendor of the product to inquire about a driver. 

Mine was purchased from Sainsmart...  at first they did send me the older software which did not work.  After that, they have not responded to my last three emails.  Wish I could get this scope working on my small laptop....  Loved it when it worked.....

I can not have working version 1.3.1 in Windows 7, byt no problem with version 1.2.0
Can you please put a link to version 1.3.0

Thanks

Version 1.3.1:

Muchas gracias

Bugs:
 

Unfortunately it doesn't work 
Splash appears on startup, 2secs later it crashes, Win7x64

[doctormord]

Version 1.3.0 is here:

http://m5.img.dxcdn.com/CDDriver/CD/sku.271544.rar

Did tested the 1.3.1 only on Win7 32bit, no 64bit avail here to test.

Try .net Reflector 8.5, this seemed to give better code quality - but there's still code to fix afterwards.

[zp1956]

Unfortunately, I haven't tested version 1.3.1 on 32 bit platform. I did a test on 64 bit platforms only (Win7 and Win10), since I am working on such platforms.

Anyway, I will give a try to my own recompiled version.
ps. thank you for advice in your pm.
