SIGLENT SDS1102X-C, supported languages issue

[Othman]

hi everyone
i just have got a new siglent scope from China wich is SDS 1102X-C. this model is 100MHz bandwidth and 1GSa/s.  i just found that this model is for Chinese market only and does not support any languages except Chinese. unfortuantly i can't read chinese and don't want to learn it.
i'm wondering if updating the firmware to the SDS 1202x-E firmware would solve this issue.. i have checked the hardware of this scope with Dave's video here:
i found that the hardware of this scope and the SDS1202X-E is identical except some changes in the analog front end section.
what would you advise me guys?

Welcome to the forum.

Unfortunately you didn’t do your homework before buying this China Only version of the 2ch X-E.
If you get to find or build a cfg file to allow conversion to a X-E you might have the 2nd 100 MHz unit in the west next to the one Dave has that Siglent sent him for review before release.
When they saw him examine the file system with a view to hack it Siglent countered and only released the 200 MHz SDS1202X-E to the west.

Your X-C model is very likely identical HW to that in X-E models.

thnaks tautech for your reply
so updating the software could not solve this problem? what would you advise me for getting the CFG file, forgive my silly knowledge about this issue.

CFG files when run open the instruments OS to accept significant OS changes from firmware like for a significant update or different branding than OEM....or a language change.
I looked quickly through my SDS1202X-E updates for a CFG file but I don't have all versions on this PC.
I also had a quick search here on the forum and again I don't seem to remember a CFG for SDS1202X-E however there may have been one but I can't remember.
You could check all the 2ch SDS1202X-E firmware versions here:

Sorry that is a bit of work or have a look here as this thread is a little goldmine of goodies:

@tautech,

Search the .cfg file inside your X-E and share it here.

[tautech]

@tautech,

Search the .cfg file inside your X-E and share it here.

Linux/Telnet noob here too scared to try. 

Others far more capable with SDS1104X-E or SDS1202X-E need do this for the OP.
Then we'll have something we can share next time someone buys the X-C version.

[Othman]

i'm not familiar with these stuff honestly. but i'm not scared to learn and try it on my own scope. so may you could orient me to do the important steps.
more help would be great, thank you for your concerning

[mushroom]

Maybe this could help telneting your scope and accessing the file system; it's about the 1104, but the shell scripts could work for the 1102 (generic commnds) :

See post 345

[tv84]

Correct, although the link is https://www.eevblog.com/forum/testgear/unlocking-siglent-sds1104x-e-step-by-step/msg4292821/#msg4292821.

Connect inside and share the .cfg.

[mushroom]

Remember I have a 1204, not a 1102 !
I'm connected but not familiar with the Linux OS and file system. I only use Raspberries for 3D printing, and the first thing I do is installing Samba and share the root directory so I can navigate from the Windows Explorer.
I don't what to search for and where to search... Could take some time !

[EDIT] discovered a VNC server !

[EDIT 2] the only cfg file seems to be "./usr/bin/siglent/firmdata0/sys_cfg.cfg" on my SDS1204X E . Not sure it will be usefull to the OP

[Othman]

thanks guys for sharing
let me check and try
i have checked the Uboot os version on my SDS1102X-C. it is 8-1 . do you think the shell scripts on post 345 would work for this os version ?

Which thread ?
We need someone to pull the cfg from a SDS1202X-E for tv84 to work his magic on it to create a SDS1202X-E CFG file.
There are many on the forum except for SDS1202X-E and you can find many references and copies of other CFG files with a 'Siglent CFG' search. Trouble is, none are correct for your scope.

[Othman]

i m just about getting familiar about these stuff. i'm still searching and learning meanwhile someone who has the SDS1202X-E model provide us with the needed CFG file.

[Othman]

hi i was trying to telnet my scope SDS1102X-C in order to explore the System files. but it seems i couldn't establish the connection right. i tried use the port 23 and 22 and the port 9999 using the script method of this post: https://www.eevblog.com/forum/testgear/unlocking-siglent-sds1104x-e-step-by-step/msg4292821/#msg4292821
and also i can not connect to the webserver when put the scope ip on browser!
the only connection i have managed to establish is the one that use the port 5024 which is for SCPI commands.
 i think i miss something can you guys help me solve this problem?
thank you in advance

[tv84]

Execute the script procedure again and then, with your PC, do a portscan to see which ports are open in the scope.

[Othman]

sorry, noob here.  i didn't get it how to do scan port of the host (scope) on my pc. could you please explain more?
thank you

[tv84]

sorry, noob here.  i didn't get it how to do scan port of the host (scope) on my pc. could you please explain more?
thank you

Just use these recent instructions.

[Othman]

@ tv84 here is the result

[Othman]

finally i did some progress!
it seems is a firmware version issue, that is why i could not log in my sds1102X-C. i had to load old FW labeled SDS1002X-E_1.3.17R1_EN on siglent website. please see the new system status.

i have attached the configuration file 'sys_cfg.cfg' of my scope model as well. please check. may tv84 would find something interesting.
thank you in advance

Let's try and cook some solution.

[tv84]

What is the answer that you obtain to this SCPI command?

MD5_PR?

[tv84]

I could adjust other things but let's try only the language.

Replace you .cfg with this one and report what happened to the language.

[Othman]

Thanks for your reply
I will try replacing the file tomorrow. Now i can not reach my scope

[Othman]

What is the answer that you obtain to this SCPI command?

MD5_PR?

i have checked this command, i got sds1102X-C as a result. btw i can register this scope to be 200 MHz following the instructions that use key generator based on scope ID and scope serial number.
i tried it and it worked and therefore MD5_PR? result in that case was 1202X-C  then i returned back the 100 Mhz key. so if this would help for configure the scope model to X-E i can do it.

[Othman]

just for a reference this X-C model has all the files of the others languages in the path /usr/bin/siglent/config/ui_data/

[Othman]

tv84, it works!
replacing the configuration file sys_cfg.cfg with the one that you have edited allowed the other options for setting language. i set the language to english and it work fine.
for just a refrence the system status shows the product type is SDS1102X-C the 'MD5_PR?' return 'SDS1000X-E' though!
so may we need to do more changes i think. and i'm wondering if this would still work when updating to the newest version 1.3.26
thank you

[tautech]

Would you mind showing us all the pages in the Utility menu please ?
That should take 3 possibly 4 screenshots.
TIA.

[Othman]

sure! here are the 4 pages of the utility menu. remember these utility submenus are for old fw version. the 1.3.26 may has some changes

[tv84]

so may we need to do more changes i think. and i'm wondering if this would still work when updating to the newest version 1.3.26

Go to my .cfg file message and replace with the new file that I attached.

You should:
- have the X-E model names
- be able to upgrade to 200 MHz (with X-E model name)
- update to the newest X-E FW versions with no problems

[Othman]

Go to my .cfg file message and replace with the new file that I attached.

thnak you for your reply
you mean the new file 'sys_cfg_1102_X-E_ENG.zip' right?

[tv84]

Yes.

[Othman]

after replacing the new cfg file 'sys_cfg_1102_X-E_ENG.zip' and upgrading to 200Mhz i have got now SDS1202X-E model name for my scope SDS1102X-C.
one thing i would ask about it. it is possible to maintain the root login when updating to 1.3.26 version? if it is.  what should do before ubdating?

[tv84]

You can continue to use the script in the USB disk at boot.

Or place a call to telnetd in a start script.

[Othman]

the script in the USB disk didn't work with me for the last fw version (1.3.26). it seems that with this FW the port 23 is closed while this port is open with the old FW as i notice that when doing port scan.
therefore i can't figure out how to telnet my scope in order to log in as a root. have i missed something?

[Othman]

last update.
 i have updated my scope to newest FW 1.3.26 version. and every think it is ok. i would to thank everybody who was generous and patient advising and helping me especially tv84 who did the important work for reconfiguration the scope.
thank you guys i really appreciate your efforts. and i'm pleased to help any body who might would face the same situation

One note.
Still (afaik) it is not same as SDS1202X-E

You can check it easy.
Generate example 40000 pulse single burst. Set Burst frequency to 400kHz (pulse period 2.5us)  and pulse width (example) 200ns.
Set oscilloscope: 1 channel on. 50ns/div.  Trig rising edge. Mode Sequence and set trig so that it capture only single sequence. Set segments in sequence exactly 40000.
Start single sequence.
After then start pulse generator so that it generate this 40000 pulses burst only.
After it have done, look if oscilloscope have captured every pulse. You can after this see this pulse on screen and also you can see in history there is exactly 40000 pulses.
If not, it is not SDS1202X-E and not ewven SDS1102X-E. It is still SDS1x02X-C  but with languages.

But if there is in history now 40000 segments then it is as SDS1202X-E  (SDS1202X-E can do even bit faster in real.. bit over 490000 segment/s with this said setup)
Also normal view (not sequence) wfm speed is afaik less than with SDS1202X-E hardware.

If Oscilloscope single Sequence never come ready with this settings... you can just interrupt is and go to History and look how many segments it have get... and in data table you see how fast it have been... look time stamps.

Siglent have also told C models are half speed (propably less brute force inside).

Naturally this is not meaningful at all for many users.

Also there is other methods to check is it SDS1202X-E or still  X-C but this is simple and "bullet proof".
HW is not changed!

Also Siglent warranty is valid only in China and as defined there so if meet any problems...
These are "web shop only" models. As example here https://item.jd.com/10022992281441.html#crumb-wrap
1614  CNY.

Naturally this is not meaningful at all for many users.

One note.

you might be right. this model may is different. however this thread is not about claiming that we have managed to configure the model X-C to be exactly like X-E model.
instead of that the main aim for this thread is activating the english language option so this model can support english in UI as the model X-E do.
i have got in this trouble because i had to buy siglent scope from china without awaring about the language i assumed that it would be like the X-E model with less capability and returning it back was not an option for my area where i live.

Yes, of course. It was very nice you get english language after this you have told and specially because return was not possible solution...: "i have got in this trouble because i had to buy siglent scope from china without awaring about the language" 
For you this was "Happy End" 
...and perhaps you get even bit better what you have thinked (we do not know now freq BW real change)

My comment was just note for some unknown readers that they do not think that SDS1102X-C model can easy convert to real SDS1202X-E. As you may know here is many kind of readers.

[tv84]

That was also the reason why I left both .CFG files in my previous post. Anyone can choose between X-C and X-E designations, both with all languages possible.

Is there a specific X-C firmware release? If there is, maybe the right thing would be to reflash the X-C firmware, now that we have the .CFG "corrected".

And, as rf-loop hints, you could try measure the max BW/performance the device can get. Because, one thing is certain, the 1202X-C designation is in the original .CFG file so this may indicate (for me, at least) that 200MHz is attainable.

Yes, somehow I think same about 200MHz bandwidth.
But maximum trigger frequency is other case. In SDS1000X-E models trigger re-arm time in sequence mode is down to 2.5 μs (specified 400kwfm/s) and even less (based to my tests).
For SDS1000X-C it is specified for 5 μs.
In normal mode SDS1000X-E have up to 100kwfm/s (specified) continuous average (acquisition is burst type) and up to around 120kwfm/s peak (not specified but mesured).
In normal mode SDS1000X-C have up to 50kwfm/s (specified) continuous average (acquisition is burst type)
And these are easy to measure - if have tools to do it.
Previously I told how to measure sequence mode guaranteed "up to" speed (using 50ns/div)

Normal mode maximum wfm/s speed is much more easy to measure.
Set scope factory defaults. Then just one channel on and horizontal  50ns/div. Display mode dots. No signal to inpu.
Trigger to rising edge and mode Auto and level so that it is away from trace level. Example 1V.
Connect frequency counter to backside TrigOut. Set counter gate time for 1s and counter trig level for reliable trig to these narrow pulses.
Displayed frequency is trigger frequency (1s average) what is also wfm/s
This of course need suitable counter or it can do also with other oscilloscope.



These values can very clearly differentiate X-E and X-C   (also there can be other different "speed things"due to possible different brute force in HW)

[Othman]

i might try to measure the real BW and wfm update rate once getting the right tools.

Hi, that's awesome stuff. I have the SDS1104X-C and try to get English enabled as well. So far I used the mentioned scripts and telnet to connect to my scope and got the config file. Now my questions are: How do you parse the file and what did you change in order to enable English?
Keep up the great work.

I attached the .cfg file from the Siglent1104X-C.

I attached the .cfg file from the Siglent1104X-C.

Go here. And download the C_ENG.cfg and flash/replace it (correct the name).

[MichaelEE]

Thank you!
So no difference between SDS1102X-C and 1104X-C?

Edit: I just replaced the file and can change the language. Only the system status screen says: Product type: SDS1102X-C
In the 5 minutes I played around everything seems to be working fine though.

Thank you.

Would be still interesting to know how to do it. I also want to investigate how to enable options.

[tv84]

Michael,

Go again to the link I showed and download the sys_cfg_1104_X-C_ENG.zip file. That's the one you should put in your machine.

[MichaelEE]

Thank you very much. Now also Product type is SDS1104X-C.

Great!

[alexkg]

Hello!
I got a Siglent SDS 1202X-C device. I ask you for help on how to reflash it and get the opportunity to change the interface language. From previous posts, I understood what you need:
1) download the configuration file. I can't and don't know how to do it.
2) you can update to the file posted here. But I could not update the file from the USB flash drive.

What I've done. I downloaded the cfg file to replace it with a flash drive, but I couldn't install it. What am I doing wrong?

Please, if possible, explain to the delitant how to perform these procedures. Step by step if possible.
Thanks in advance.

[Othman]

Dear alexg you should know some basics of Linux/Telnet to get the job done! if you don't have Linux on your PC you can use Putty or you can activate the Linux Terminal on windows check this: https://allthings.how/how-to-use-linux-terminal-in-windows-10/
i will summarize the steps with some details. i would to mention that this way might be not the best way to do it but it is the one that worked with me. the steps are as the following:
1- load the older FW version SDS1002X-E_1.3.17R1_EN on your SDS1202X-C scope. because with the newest FW you can't establish telnet connection with your scope "the port 9999 is closed" you can find the old version here: https://siglentna.com/service-and-support/firmware-software/digital-oscilloscopes/#sds1000x-e-series
2- connect your scope with a router or a switch by ethernet cable don't forget to enable the DHCP server in your scope lan configuration and notice what is the IP address of your Scope.
3- connect your PC with the same router or the same switch then open Linux terminal on your PC or Putty terminal  and try to establish a telnet connection as a root with your scope in order to access the file Systems. type this command : telnet <your scope IP> 9999
the user name is "root"
the password is "siglent_sds1000x_e"
4- copy the file "sys_cfg.cfg" in  this direction "./usr/bin/siglent/firmdata0/sys_cfg.cfg" to your USB disk, you should know some basic Linux  command to explore, copy, delete and mount a drive to do this job.
5- share this file with "TV84" to do the magic job then you will replace the file with the new one that might "TV84" offer you.
6- check if every thing is going well then update the FW to the new one again the newest version is 1.3.26.

[tv84]

5- share this file with "TV84" to do the magic job then you will replace the file with the new one that might "TV84" offer you.

No need to do this step. You just need to overwrite with the appropriate file (attached by me in a previous msg). The .cfg are the same for all scopes in the same situation.  Make sure you rename the intended file to "sys_cfg.cfg" before overwriting, and sync.

i thought the CFG of SDS1202X-C model  might be different from the SDS1102X-C. thanks for clarification.

5- share this file with "TV84" to do the magic job then you will replace the file with the new one that might "TV84" offer you.

Do you need to overwrite the configuration file by executing commands in telnet? that is, connect to the device via telnet and give a command to replace the file?
or can this be done from a flash drive in the oscilloscope menu?

Yes. So, it's better for you to ask for someone who knows linux to help you with hands-on.

[alexkg]

I asked my friend to help me, he is familiar with Linux.
There was a problem, when connecting to the device via Telnet, only port 23 is available. 9999 port is not available at all. When downgrading the firmware, as advised by Othman, port 9999 is still unavailable.
How else can I access the device?
are root correct? :
username is "root"
the password is "siglent_sds1000x_e"

[tv84]

Use port 23 (default telnet port).

dear alexkg have you managed to transform your scope? may i can ask you to share here the Acquisition mode menu of your scope, this is a submenu of the acquire menu. i think my scope miss the High Resolution option, can you confirm that with your scope!

[tautech]

dear alexkg have you managed to transform your scope? may i can ask you to share here the Acquisition mode menu of your scope, this is a submenu of the acquire menu. i think my scope miss the High Resolution option, can you confirm that with your scope!

Correct.
To be equivalent to SDS1202X-E it needs the ERES menu.

Yeah.
The SDS1202X-C is not the Chinese version of the SDS1202X-E, not at all even it looks outside like it.
It's a bit different. It is also an "web shops only" model series and only for the Chinese domestic market. That model is also clearly slower than the X-E series what is also told in data sheet. Well, when you stretch a penny, you get a stretched penny.

Same for all these models:
SDS1104X-C 100 MHz
SDS1204X-C 200MHz
SDS1102X-C 100 MHz
SDS1202X-C 200MHz

Unfortunately, I don’t have the opportunity to deal with this device now, most of the time there is no electricity, it appears for a couple of hours.  There is a war going on in my country.  As soon as the results appear, I will share them.

I want to ask you to bring this data here, the difference in technical characteristics.  Unfortunately, I did not find a difference in technical characteristics between the X-E and X-C versions.  Externally, the devices are one to one, the difference is only in the name of the models we will be grateful if you share the information that you found, where it is said that the model for the domestic market is slower than the one that is exported.

In WFPS which is an indication of system speed.
Sequence mode (fastest)
SDS1202X-C = 200k
SDS1202X-E = 400k
https://www.siglent.com/upload_file/document/SDS1000X-C_DataSheet_DS0101E-C04A.pdf
https://int.siglent.com/u_file/document/SDS1000X-E_DataSheet_EN04D.pdf

We also see the 400k spec in 4ch models, SDS11/1204X-E and SDS1104X-U.

There are always small differences between China only and western market models.
China sellers that export China only models are asking for big trouble if Siglent finds which of them sold it.

It is not so that same model in China domestic market and Exported officially is different. Example SDS1104X-E in China domestic market area is perfectly same as SDS1104X-E  Exported officially (only different is example power cord depending target area etc but oscilloscope itself is just same.
Do you have any idea why they then manufacture SDS1104X-C model if itv is perfectly same. Do you may be think they are idiots. Only for different model sticker.
This whole X-C serie IS different even when it use same exterior. Also, it is made only for China domestic area web shops and NOT officially available for Export. Siglent official web side do not even give domestic CNY price for these inside China web shop models but all normal models have there MSRP and currency CNY for China domestic markets. But special "el cheapo" web shop models have not.

One example is analog front end what is different. Look three voltage bands change level.
C 500μV  ~ 150mV: ±2V,  E 500μV ~ 118mV:   ±2V
C 152mV  ~ 1.5V: ±20V,  E 120mV ~ 1.18V:  ±20V
C 1.52V  ~ 10V: ±200V,  E 1.2V  ~   10V: ±200V
This mean there is some real reason for this difference even when difference is not so big in these values.

Also wfm/s speed is different
Normal  acquisition  C model up to  50kwfm/s, Sequence acquisition up to 200kwfm/s
Normal  acquisition  E model up to 100kwfm/s, Sequence acquisition up to 400kwfm/s


AC low freq. -3dB   C model 10Hz  E model 2Hz

DC offset accuracy is better in E model when ≥2mV/div

In 2 channel models C and E series Ext trigger some differences (freq limits)

Also I can not find Gated measurements when I look C models data sheet or user manual.

Then I can notfind Counter, sample logger and data logger function in 4 channel C model but in 4 channel E model there sure is. Also not NTP function.

[tautech]

Yes but we are talking about 2ch C model not 4ch.
There is already enough confusion with Siglent's alphabet soup of models even in the X-E range and the inconsistency of feature set in this model range/series.
Just compare SDS1202X-E with SDS11/1204X-E then drop in SDS2000X-E....it's a mess whereas they scream for some consistency of features. 

They each have their place but it could be so much better.
****X-C models are just what they are, designed and built to a specific price point.

Why I include both, 2 and 4 channel models.
Because SDS1000X-C  whole serie is elcheapo versions from whole SDS1000X-E  series including 2 channels and 4 channel models.
And differences are in both, 2 and 4 channel models. Then, as we know, inside E series between 2 and 4 channels are many differences and inside E series between 2 and 4 channels are many differences.
2ch C is different from 2ch E
4ch C is different from 4ch E  (and in my previous message I noted also these differences in 4 channel versions group.)

This was for argumenting that whole C series is different (of course I see that in this particular case talking was just about 2ch model), not only 2 channel versions. And all C versions are _only_ for China markets, not for Export. Lets hope Siglent do what they need do before whole mess. Stretch penny and you get stretched penny. Outside China here is not any warranty or other product support for these models and must not be, except some kind individual citizen people may help.

100%
Further, Siglent penalties to China exporters are severe as we discovered when reporting a SDS2074X Plus exported to NZ.

Which is very reassuring that Siglent want to protect their worldwide distribution network from their China sellers export of China only models.

Siglent is a listed company (Shanghai 688112:SHH) whose purpose is to generate profit for shareholders. It is not an aid organization.

"Siglent wants to protect its global distribution network from Chinese sellers who only export models made in China" 
Right!

Everyone wants to protect themselves and their business and this is one extremely important thing in that. We cannot change the fact that China's domestic market is completely different from the foreign market of a Chinese company. They don't work the same way. Therefore, these two "worlds" should not be mixed without harmonized rules of the game.

Of course, when I know China to some extent, I can understand these merchants from some perspective, but understanding and accepting are two different things. Be that as it may, many of them are just supporting their families. But, it should be done in acceptable ways.

Also wfm/s speed is different
Normal  acquisition  C model up to  50kwfm/s, Sequence acquisition up to 200kwfm/s
Normal  acquisition  E model up to 100kwfm/s, Sequence acquisition up to 400kwfm/s

in your opinion what is the potential hardware difference between the X-C and X-E model that might lead to this specification difference?

new update about SDS1102X-C scope.
i tried to measure the waveform update rate for the chinese version of SDS1102X scope. i used the built-in frequency counter of my HDS242S scope, i've got arround 85Kwfm/s peak and 80Kwfm/s in average, here a photo for the resulte.

[alexkg]

Hello dear!  I ask you to help me reflash my device, my friend did not succeed.  Please write a step-by-step instruction with full instructions for replacing the firmware.  If it is convenient for you, my email is alexkg@ukr.net.

[tv84]

Remount as RW.

[tv84]

Don't be greedy. Remount only /usr/bin/siglent.
