I am a technical support engineer from Siglent, and so glad to offer effective technical support, trouble-shooting and problem solving for all Siglent products.

Also, we will appreciate if you could share your experiences and some improvement suggestions with us.
 
Sincerely,
Jason, SIGLENT North America

Hi Jason,

Is there a update of the SDS800XHD coming in the next few months? The scope has quite a few bugs and issues that need to be resolved in my opinion. (See my signature)

Jason hasn't been with Siglent NA for a few years!!

Just talked with Siglent NA today, we have an issue with an older DSO probe. This is an older DSO probe, well out of the warranty period, Siglent could have said, "sorry but that's been discontinued and well out of warranty", and this was what we expected!!

However, Siglent NA is handing the issue with a replacement of a discontinued out of warranty probe

I would like a device that can do everything I want it to do, and for pocket money.
And if I find something on the device that I think isn't right, then the manufacturer of this cheap device had better drop everything and make sure that the device can do everything I want it to do.
If they don't, it's a shame, considering how little I paid for it to do everything.
I personally now have a collection of devices at home, the individual value of which easily runs into the tens of thousands—and none of them are perfect.
I don't mention this in my signature, nor do I whine about it, because I know the realities.
Get over it or just leave it alone.

Well his account was last used in august this year, so i posted here, when i found this topic.

I have worked together with electronics hobbyist on a many issues, but he hasnt come back yet. It seems his work on this forum (for siglent?) has been finished.


I believe, replacing a probe wouldnt fix a single issue from my list.

As it turns out, not everything is about you.

There must be a Siglent website that serves your location.  They more than likely have a page where you can place a request.  Whenever I do this at Siglent NA (the website that serves my geographic location), I either get a phone call or an email either the same day or next, and I am absolutely nobody.  Did you try that?

No one said this. I was talking about the Siglent SDS800X HD series. Sorry to have confused you.

I did that, but there is not much progress to be seen here yet. Maybe they are focusing on a answer to Rigols MHO98?

You said this. Mike mentioned Siglent taking care of an issue with a probe, which was his experience. Your mention of the probe attempted to make it about you.

You should try contacting Siglent directly with your issues. Or a therapist.

Siglent extend their thanks and best wishes for the holiday period.
We have some more new products coming for 2026.....

Stay well and safe everyone.

[eTobey]

We have some more new products coming for 2026.....

But will there be new firmware updates?

Oh wait... its not to late...

Dear Santa...

 

[eTobey]

Unfortunately, Siglent has done nothing about this specific problem.

I feel you, my friend!

For some companies it seems that there a low priority on fixing issues. The priority mostly lies on bringing out new stuff that will probably have yet again issues that need to be fixed.

We have some more new products coming for 2026.....

Buy a Rigol MHO900, and you can create your own firmware as often as you want and however you want.

Really?

[Martin72]

At least that's how it appears to me, see Norbert's mods for the scopes.
As for Siglent:
They launched two major updates for their scope (SDS800X HD) in both the first and second years—that's a high rate, surpassed only by Batronix Magnova.
But that's no surprise, because Batronix only has one project to manage, while Siglent is a multi-vendor in the field of measuring equipment.
Therefore, one cannot expect the updates to be released more quickly.
However, this is what is being done here, and people complain when it is not the case.

[SiliconWizard]

Oh, well Norbert's work is based on decompiling I think - that's very tedious and it's not quite like being able to create your own firmware entirely, although with a lot of time spent reverse-engineering it, it might be possible.

It's probably possible to do the same with the Siglent scopes, and it looks like they are Linux-based rather than Android, so that should even be a bit less of a headache to do so?

Dear Siglent,

I bought a NEW SNA5012A months ago with the rather expensive TDR option.

I am running into the following problem.
When I have a short DUT I encounter the following message:

DUT lenght is shorter than 14.70588ns

I have passed this on to Siglent EU distributor and asked for a solution months ago.
And I got the answer that it was passed on.
After installing the new firmware several things were resolved, thanks again for that.

Unfortunately, Siglent has done nothing about this specific problem.
I also own a Keysight E5071C network analyzer (TDR option) and it does not suffer from this problem at all with exactly the same setup.

Do you have a solution for me and probably many others?

Marcel

I just hope you explained what exactly was the problem better when you asked for help.
Because we cannot even understand what are you complaining about with no explanation of details how you came about to get this message. Not saying you do not have some problem. But that is exactly it, all we know is you have some problem.
A bit more detail about circumstances, setup and such could help. For all we know, manual might not be clear and you are simply doing something wrong. In which case manual is the one that needs fixing or improving, and device works fine.
Still a problem that needs fixing, but this time it is actually properly identified, so it can be actually fixed.

Claiming that doing exactly the same thing on a completely different device and it works there is not relevant.
It is obvious that TDR option should be able to resolve less than 14ns worth of length (1,2-1,5m) of cable.
Something is wrong, and I do not mean cabling, but in how instrument is parametrized.
No need to check that with other instrument.

Or is cabling setup and calibration/de-embedding something specific or unusual, so it cannot be parameterized into instrument, or it was, but instrument does not accept it or calculates wrong....
Or maybe you are trying to use expecting it should be used exactly the same as other instrument, but this one actually needs different workflow, being, well, different instrument from different manufacturer.

Like I said, it is like walking into service and saying "Something is wrong with my car. Fix it." and walking away. With no further explanation. Makes it hard to even know where to start... Much less to expect a solution..

[2N3055]

Hi 2N3055,

Both TDR options are practically identical, and this is clearly a Keysight copy.
Again, the exact same setup, use the wizard, but Siglent doesn't accept electrically short DUTs.

I contacted the Siglent distributor and they were aware of this problem.

Thank you for explanation..
Yes that is a limitation for sure.
I asked because it was not clear, and I don't have that device so am not aware of how it is implemented.
As long as they accepted it and understood, there is only now to wait.

It's probably possible to do the same with the Siglent scopes, and it looks like they are Linux-based rather than Android, so that should even be a bit less of a headache to do so?

As far as I know, all current Siglent models are based on Linux.
Whether it would be easier to modify something in this way is beyond my knowledge.
Personally, I wouldn't change anything about the scope, even if I could in the sense that I understand something about programming.
A usable scope is not an Arduino project where anyone who can count to three can modify something.
It was developed over many years by a whole team of engineers, so it would be presumptuous to think that one person could do better than them all together.
That's why I steer clear of such things.

Adding at least one non alphanumerical character on the keypad, or having files beeing saved as 0000n.bin instead of n.bin (for proper sorting), I would consider as easy as counting to three.
Or not having the screen beeing cleared in rollmode, when I take a screenshot.

Some new products spotted at https://www.siglent.com/ ....unknown western market release.

PXIe mainframe


Modules






USB VNA

[BillyO]

A little beyond my budget 

Us hobbyists should benefit from some trickle-down though 

[tautech]

Another new product...unknown release to western markets.....

[eTobey]

It would be good to improve existing products too, rather than just creating new ones that have the same UI quality?
