Re: OWON VDS1022I Quick Teardown (versus the Hantek 6022be)

Hello.
I am going to buy a VDS1022i for measuring noise several USB Chargers(hobby).
I would like to receive your help and i have some questions.

1. What is the latest hardware version of the VDS1022i?
(Eg, Rev 1.5 or Rev 1.6 or Rev 1.7, ETc)


2. Which of the P2060 or P7060 probes are included in the VDS1022i?
(Some say P2060, others say P7060(with photo))


3. Which is the better probe?
(P2060 is up to 200 voltage at x1, P7060 is 300 up to voltage at x1. it seem that another spec are same.)


I would appreciate a reply. :)

Hi,

I don't know if there is a record of current H/W revision. Mine (that I did the original teardown on) was an early one, I've seen later ones with copper foil wrapped over the edge of the PCB between the upper and lower screening cans as a grounding contact for the case. The latest revision that I've seen (from the look of it) is shown in this recent video...



The only functional difference that I can see (apart from the bare tinned tracks down the edges for case grounding) is that the Video trigger chip doesn't appear to be fitted. I suspect that nobody is particularly interested in looking at analogue video in fine detail these days.

I don't know what PCB versions various ebay sellers stock these days, possibly random, but it doesn't make a functional difference anyway, they all work well.

With regard to scope probes, mine came with P2060 60MHz switchable x1/x10 probes, so does the one shown in the (recent) video.

I'm not sure where you have seen a P7060 photo and I don't know what the practical difference is - You NEVER use probes in the x1 position at those sort of voltages, that would be silly and dangerous for the scope, always use X10.

I note that you mentioned measuring noise of several USB chargers, I'm assuming (hoping) that you mean scoping the outputs. As has been covered many times before, this scope (and most others) isn't suitable for measuring mains. You would need to add a high voltage differential probe for that.

I hope this helps.
Best Regards, Chris

Just for help community

Method for modify texts or messages in your favorit language in software VDS_C2 (or VDS_S2) for VDS series

On desk create a copy of com.owon.vds.foundation_1.0.0.jar in \OWON\VDS_C2\plugins\
On desk create a folder named "translate"

For decompress :

With 7zip decompressed com.owon.vds.foundation_1.0.0.jar in folder "translate"
with Notepad++ (or other) open MsgLib_en.properties.jar in Desk\translate\com\owon\uppersoft\dso\i18n\MsgLib_en.properties .
Modify text only after "=" and close file.

For compressed :

open 7zip and select the 3 files : com , META-INF , plugin.xml in folder "translate"

Click on "Add"
in "archive name" write "com.owon.vds.foundation_1.0.0"
in "archive format" change 7z by zip
Click "OK"

Open folder \Desk\translate\ and change suffix zip in jar in com.owon.vds.foundation_1.0.0
Click right and copy file com.owon.vds.foundation_1.0.0.jar

For test :

Open folder \OWON\VDS_C2\plugins\
Change name  of com.owon.vds.foundation_1.0.0.jar in com.owon.vds.foundation_1.0.0.jar.old (for protected original file).
Click right and paste file com.owon.vds.foundation_1.0.0.jar

Change Menu/Utility/Language

For modify texts in tips :

Open \OWON\VDS_C2\docs\VDS_C2\en\image\
Protected original image *.png in *.png.old
Open your image *.png with Paint-net
Modify and save

Welcome to the forum camomille, and thanks for the helpful information - I have been wondering how to modify things, this is a good start (I'm not a Java programmer).

Now if only you could find a way of making the 'Save' icon on the main screen (2nd to the left from the Home icon) bring up the save image box rather than save text one I'd be really happy! Having to go into the Utility menu to save an image has always been a pain.

to Gyro, thank you for your welcome

I am not a Java programmer ,  the *.jar files can be decompressed and recompressed like Zip or Rar files with 7zip.
The button "Save the waveform" corresponds to command "Tooltip.Save" of the file "ButtonPane.class",
but *.class files must be decompiled recompiled and I do not know how to do it.

Thanks, that gives me somewhere to focus on. I've never bothered contacting Owon about this one, though they've been sort of responsive at times in the past. They must have had some reason for making that a Text save button but it makes no sense to me.

Off to do some reading...

I m looking for a way to stream data from a OWON VDS1022I to a ftp server and from there to Matlab. Matlab has support for Oscilloscopes and has a great potential to plot, visualize and analyze data.

Is there a way to modifiy the code of the VDS1022I to stream data to an  ftp server?

It is probably not necessary to modifiy the code of the VDS1022I to stream data to an  ftp server and from there to Matlab, since Owons own software has a integrated SCPI interface and Matlab supports SCPI commands:

https://www.eevblog.com/forum/testgear/owon-ag-1012-awg-matlab/

It would be nice to have Matlab support for the VDS1022I. Does someone know how to use the SCPI interface of Owons software to connect to other applications?

Sorry, I've not used the SCPI interface on the VDS1022I S/W but here's the interface spec/protocol document in case you haven't already found it... http://files.owon.com.cn//software/Application/VDS_Series_SCPI_Protocol.zip

Some of the higher end VDSxxxx models have ethernet interfaces but are possibly outside the price range you're interested in.

Yes, I found this documentation already. It's probably a step by step procedure to get Matlab support for the VDS1022I, when nobody did use it before. There are also expamples in the Matlab community for other oscilloscopes which could be modified for the  VDS1022I. Matlab would be great for the VDS1022I, since Matlab is really wonderful for it's possibilities.

I'm looking for a solution for a respiratory sensor to connect to the VDS1022I, which is mobile. And the VDS1022I could be suitable for it. To avoid to carry around a laptop for the VDS1022I  all the time, I thought about connecting the VDS1022I to a Rasperry Pi. Rasperry Pi has it's own Linux based OS. I saw here a Linux version of the Owon software in this blog. Do you think that this version could also work on a Rasperry Pi?

I'm sure Matlab support will be a really welcomed feature if you can achieve it, but it does look as if you will be forging the path (unless you get lucky).
 
Yes there was quite an effort a while back in this thread about Linux support, I think various people got it working. I can't see a fundamental reason why it shouldn't work on a Pi [EDIT: would also be a really desirable capability] (ensuring sufficient USB supply current might possibly be one easy to solve issue). The VDS1022 device/FPGA image is easy to find in the s/w if you unzip it, as is the Java source.

Others will hopefully chip in with a more knowledgeably replies on the Linux stuff.

Nice to read the view of an expert and to profit from his knowledge :).

Regarding power consumption: Do you have experience with the power draw of the VDS1022I? What battery capacity would be necessary for using for 24 hours, for a whole day?

Haha, I wouldn't consider myself an expert in the field of Matlab, Linux or Rasperry Pi!

I haven't measured the power consumption of mine specifically, but earlier posts indicate that it is in the range of 300-400mA (the internal isolated DC-DC converter is a 2W one) -  this may pose you a problem for long term battery operation.

You say you are not an expert for Linux, Rasperry Pi and Matlab? But are you not the expert here in the forum for OWON VDS1022I? Thanks for the information about power consumption for the VDS1022I, very useful, VDS1022I expert!

I m one step further with the SCPI communication between VDS1022I and Matlab. I found an example in Matlab for the SCPI communication between a Rigol oscilloscope and Matlab, which could be modified for the VDS1022I and tested.

https://www.eevblog.com/forum/testgear/owon-ag-1012-awg-matlab/

And if it does not work, asking Owon s  tech support for help could solve the problem.

 SCPI seems not to be very often used, but looks not too complicated. I m convinced that this can be solved by everyone who want s it for the VDS1022I. And the solution might be not very difficult.

Ha, well I suppose I do have that dubious honour - I guess somebody had to be the first to buy one 'sight unseen' and pull it to bits! There is the odd Youtube video now which is useful for seeing the UI but pretty much all searches still go either to sellers or end up here.

It sounds as if you're making good progress already on the SCPI. I must admit that I hadn't got much further than scanning the SCPI spec and thinking, hey that could be really useful. If you can integrate it with the AWG and maybe a PSU (there's a thread around here somewhere about someone doing an SCPI controlled PSU) then you've got a really useful setup, even if a bit frequency limited. You can always go up to one of the higher VDS models later with little if any effort - the SCPI spec seems to cover several models.

If you really get stuck, I think I've still got the email address of someone in Owon's technical department. I last used it a couple of years ago when I had an issue with one of their S/W releases so it may not work any more. PM me if you need it but I'd keep it as a last resort.

This is the progress of my research concerning the recording of the screen with the "Save the Waveform" button on the front panel.
I am not a Java specialist, but it serves me as an example to learn the language.
The change works (after a lot of testing), but I can run it with "org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar" not with "launcher.exe".
To continue, I will need sources and I want to ask Gyro to reactivate a download link for older versions of the software for track the sources.

Hi camomille,

That looks very encouraging, I'm glad you are getting some benefit out of it as a learning experience.

Yes, of course I will re-upload, the only problem is that I am somewhere with ridiculously slow upload speed at the moment (as in <10kbps a lot of the time) and the connection keeps resetting. I will try again tomorrow.

In the meantime, if anyone else downloaded a copy of 'VDS1022 Previous Versions.zip' last time then maybe you can help...?  :)
Best Regards, Chris

The upload speed was a bit better this morning (only took 45 mins :D). Here's the download link:

https://ufile.io/4lllcvgx

It might take a couple of attempts to download using the free option, I need to find a better upload site!

Perfect first attempt 16 minutes.

Now a lot of work to analyze and compare.

Thank you for spending time.

Oh yes, almost certainly! Owon have been known to be a bit 'clumsy' about software releases.

As it happens, 1.0.23 was a particularly good vintage, with no bugs that I am aware of,  so it's nice to have the sources for that one.

That looks excellent, I assume that you still can't get it running from Launcher.exe.

I had a (well actually more than one!) rainy day on holiday last week. I couldn't even find which files to edit. Clearly your Java skills are evolving faster than mine.

In frustration, I did play with the button icons though, inspired by your reply #316 #312.  It's little sad I know, but the cartoonish 3D effect Autoset, Run/Stop and Single trigger buttons on an otherwise professional looking UI have always bugged me. I have generated some which I think are better. These are in the 'com/owon/uppersoft/dso/image' folder of the unzipped com.owon.vds.foundation_1.0.0.jar

The single trigger icon might not be the ideal but I couldn't think of anything better, it's hopefully more meaningful than a simple 'S' anyway, and certainly more so that the original 'lightning bolt'.

Here are the 'before and after screenshots, complete with the png files, under the correct names. No recompilation was needed.
