Just want to add my comment on the language issue with the SDG1025. I am the proud winner of Siglent's fourth giveaway and I received my generator 2 days ago. Been having fun playing with it and I must say the user interface is very intuitive. Have not read the manual yet but have been able to view most of the functions on my SDS1052DL, Asking to choose a language everytime it boots up is very annoying. I can see it asking the first time or maybe a few times but everytime is nuts. Siglent please fix this. I haven't had time to fully investigate everything with this generator but just a cursory look seems to show a lot of overshoot on the square wave. I will investigate this further when I have the time. So far my only complaint is the language issue.

You are indeed able to verify that the file is from a certain author by looking at the certificate (with or without redirects). The reason why redirects are not an issue is because it does not matter if you download the file from a malicious website, as long as the file is digitally signed and the digital signature show that it has been published by the expected author, it means that the file is good (this is the whole point of a modern file digital signatures). Your comment about keeping your computer virus protection up to date is obviously valid, but having a digital signature that can prove the file comes from a trusted source is far more valuable and effective (IMHO).

Thanks for your explanation of file signing, this was my general belief too.

You raise a side issue, the availability of files.
Siglent's files are now freely available, no need for them to be hosted by others, so if Siglent's repository is secure any risk is reduced although not eliminated.

We understand signing is the norm in the western world, and I'm quite sure Siglent is considering their response as we type.

Very likely the connection method you are using.
This is very important for faithfull reproduction of any fast rising edge.

Some reading for you on this matter from a recent thread:
https://www.eevblog.com/forum/testgear/show-us-your-square-wave/

Many results posted are a result of improper connection methods, a good browse will show them up.

Here in the western world no financial entity would in fact place their security for transactions in a signed digital file. Security for those types of transactions are handled by encryption and secure end to end connection from client to server. I can understand his searching the internet for facts but just like a commerical here in the USA. No one is allowed to publish anything on the Internet unless its true. Google that you gind that to be true. Again digital signatures are a deterent only and by US law they cannot be used for any legal transaction. Exception of corp to corp.

Repeat after me, Digital Signatures Are Used For Authentication Purposes!

Are you aware that you can edit the windows registry to tell it to ignore cert errors! Then load a patch program so you access the file change it.

God! I keep getting sucked into this! Tonite I am going to take my phd in mathematics, my two masters in computer science and cryptography and burn them.....

Ok, I am done and promise I will not reply anymore to this particular topic. I swear, really, I will not reply! I promise....It will not happen again...

Yes, you are right, once you have set the language and set 'poweron' to 'last', the language will be remembered. so just ignore the language selection while you boot up next time.

Hi, Siglent. Do you think future firmware updates of SDG5000 family will enable channel coupling function, if hardware supports it? Thanks

Hi, Siglent, so we know HW can support this feature, it would be a great idea for the next update...

This doesn't work on my SDG1025, however it's a trivial issue to me.

Now the interesting thing with the new firmware is the ability to upgrade with a license key. Any news on this? Where would one obtain a key and what sort of price? Online keygen direct from Siglen, or going through old fashioned mail order resellers for a piece of paper?

Would hardware upgrades be required? IIRC the lower spec SDG1000 series don't come with a fan for example.

IMHO Rene is just kicking up dust.
I agree with Docholiday: Keep the anti malware & virussoftware on your PC up to date and look where you download files from.

There is no way to ensure that even a signed file is really from the author if you don't check where you download it from. If you have malware on your PC which redirects a web request to a different server (this is really easy to do even with secure connections!) then you'll happily download a signed file from a malicious source.

I meant to post this earlier but I got lazy. Nevertheless, I wanted to address your post to help clarify some of your misconceptions.

But do you know what the best part of a digital signature is? That if someone does not give a crap about them they can completely ignore them and move on with their lives. But for those of us who care, it is a very valuable feature.

Cheers.

Well, don't take my word for it:
https://nakedsecurity.sophos.com/2010/06/23/trojbhoqp-verisign/

Conclusion from the article:
But regardless of the would-be victims, this technique, in addition to the fraudulent SSL certificate abuse we have already seen, serves as another reminder that the mere pressence of a digital signature does not mean that something is legitimate.

If you read the article closely you'll see that the malware actually looks to be 'more genuine' than the original software!

Doesn't work on mine either, that's the cause for my complaint. I know you can just hit any button or twist the knob and this screen goes away but it shouldn't be there in the first place. Like I said, an annoyance but I really like the generator and I couldn't beat the price.

I think we all agree that no security feature is perfect. The idea here is that a digital signature is great value added that is welcomed by many (there are no harmful side effects).

I am no security expert, I am simply an observer. I see all major corporations (Microsoft, Google, Apple, Oracle, Amazon etc) digitally singing every file they distribute. I am pretty sure that such major corporations do that for a reason since they have all kind of security experts pushing the issue and they wouldn’t be wasting valuable resource if digitally signing files was a pointless endeavor.

I think is about time we stop debating this topic here, I am convinced that Siglent has very bright and capable employees capable of making an educated decisions on what to do. Let’s wait and let them decide how they will move forward.

Thanks.

I updated my SDS1102CML firmware with the version 5.01.02.29. I used the link couple pages back. In the guide provided it says to load a .CFG file. The zip package dont have it. Where I can find it?

In my experience a .cfg file has only been included when needed.
Those that I have encountered have modified the startup splash screen.

You should be safe to upgrade without it, but if you wait a day or so we can get Siglent to confirm it is not needed for this update.

In the meanwhile I'll update one I have in stock to check for you and report back.

Edit
There was NO problem with this update and it seems not to need a cfg file as explained above.

Thank you, tautech. That is what i suspected as it did work after the upgrade, but I needed a confirmation.

Hi.

My friend got a problem with his SDS1072CML during firmware update, after restart all leds on and no life signs...
I read dump from S29F064 flash from my oscilloscope for him, but anyway same, looks a problem is that my board is CA_M_101000 and his one is CA_M_110300, looks they are not compatible

Maybe somebody has dump of S29F064 chip for 110300 board?

With thanks

mine is SDS1000CNL_SSP_V100R005B01D02P13.ADS.

No one works on his board

But before flashing his one worked.

You have SDS?

CNL and with ancient crap FW version P13 and dumped its flash and moved it to SDS1072CML and then you wonder because equipment is "dead".

More strange is that current FW version numbers (for both, CNL and CML) are 5.01.02.29 (not 22 and not 13) so I wonder what is going on here. And inside flash memory these FW are really different even with same displayed version numbers (due to differencies in HW)

I saw CML oscilloscope with 101000 board(atten 1062CNL, but flashed with siglent firmware as boards are same). That's why I decided to offer my friend to flash his 110300 board with dump from mine, as it allready was dead and nothing to loose. About versions - yes, 29 is last one, mine one I flashed 1 year before and 13 was the most common board for my board (and it works fine ) and 22 was the most last version before 29 was released. Don't know why friend choosed it to flash.
So the question is if somebody have a full dump of 110300 board flash ? I will be very thank for dump as really want to help my friend with that problem. Or maybe Siglent specialist can sell flash chip with correct firmware in it ?
Or at last maybe he can sell whole board (110300) ?

tautech · « **Reply #422 on:** April 02, 2015, 05:42:12 pm »

The PCB HW version, if not printed on the PCB (should be) can be identified by Siglent with the units Serial number. Post up the SN minus the last 2 digits.
You'll probably only get one through a Siglent distributor though.
