Siglent SDS1000X HD versus SDS2000X HD

[dexar]

Does anybody know how responsive the UI is in the two scope families?
I am guessing that the SDS2000X HD is powered by a more powerful CPU but
can you feel the difference compared to the SDS1000X HD when operating it?

 

[skander36]

The best answer can be done by the one that own both models, but excepting those that get a old test v.1 of the 1000X-HD I don't think that someone will buy both models for the future.
This models does not have a CPU in terms of clasic arhitecture, but if you are refering to the application processor, 1000X-HD has a more recent and advanced one - Zynq 7000 UltraScale+ MPSoC, while 2000X-HD has an older version of Zinq - Zynq 7000 SoC.
But ... while 1000X-HD is doing the signal processing with the FPGA logic included in the same Zinq MPSOC, 2000X-HD has 2 other more powerfull FPGA's available: Spartan 7 and Artix 7 to do the processing nedeed for 2x2 Gsa/s and 4x12 bit channels at 500 MHz BW.
So the difference in power procesing of the signal became obvious.
During use SDS100-X-HD is not slow at all, except when you have more math function simultaneously for ex. FFT or nested functions.
So in terms of usability 1000X-HD does not show slowness as an obvious issue, only if you look for it you can find situations when it can be revealed. But I didn't find scopes that can't be kneel if you really want.


P.S. If you look for a model with a clasic CPU from Siglent they have SDS7000A wich feature an x86 architecture.

Thanks for the info. Now I understand why ERES is done in hw only in the SDS2000X HD.

You wrote 500MHz BW. The highest BW model of the SDS2000X HD is 350MHz according to the siglent homepage.
Do you mean that it is SW limited to 350Mhz or was it a typo?

Correct. SDS2354X HD.

However a BW upgrade to 500 MHz is available as an option....unpriced on the EU website.
https://www.siglenteu.com/accessory/350-mhz-to-500-mhz-bandwidth-upgrade/

This only supports 500 MHz with 2 active channels and just one on each ADC otherwise a 350 MHz BW limit is automatically applied.

[dexar]

Tautech, do you think Siglent will continue with updates for the SDS2000X HD. It sounds like it about to be discontinued?

[tautech]

Tautech, do you think Siglent will continue with updates for the SDS2000X HD.

100%, it is a very capable and popular model which fits well between the 8bit SDS2000X Plus and the new 12bit SDS3000X HD.
SDS2000X HD has some more and better features than SDS2000X Plus yet they are both 500 MHz designs.

In the future it may be changed to the dark scheme of the other 12bit models but this is just a guess on my part.

[tautech]

TBH for several reasons and if your budget permits, get a SDS2000X HD.

500 MHz capable platform.
SPL2016 LA probe superior to that offered with SDS1000X HD.
Considerably greater memory depth plus superior memory management tools.
User configurable trace colors.
Whisper quiet fan.

SDS2XHD-BND option bundle promotion until mid year.

[joeB]

The SDS2000X HD also includes the 500 MHz passive probes.

[skander36]

Batronix now has the SDS2000X_HD in stock at the lower price (Siglent recomended) - 2,237 E.

[Martin72]

Indeed ! (2 day ago it wasn´t showed)
https://www.batronix.com/shop/oscilloscopes/Siglent-SDS2104X-hd.html
Together with the bundle this would be maxmium insane price/performance ratio, even without the bundle.

I paid €2831 in december 2022. Doesn't matter, I rather that these things depreciate in value than stagnation with no new released devices.

[Antonio90]

It is a very good deal indeed. I had to talk myself out of buying it, as that would mean selling my two best DMMs and maybe some other stuff. As good as a deal it is, we are still talking about + €2K, which is a complete lab in itself.

[Frex]

Hello all,

I'm also interested to upgrade my bench with the SDS2000X-HD,
but I have some questions about it.
First, is there a way to unlock it as for the non HD version ? (bandwidth and options).
It seem that there is a hack,  but not publicly revealed.
Second, there is also complain about very slow update rate in LA mode compared
to non HD model,. Do this point has been fixed ?
(There is a youtube video about this issue here : )
Thank you in advance for your opinions.

[H.O]

I was about to pull the trigger when the 2104X HD was available at Batterfly the other week but when I got around to it it was gone. Oh, just as well I thought...it's not like I've worn out the 2kX+
But now, when it showed up at Batronix at the new pricepoint I could no longer resist.

SDS2104X HD with the SDS2XHD-BND bundle coming shortly.

If anyone else is ordering from Batronix don't forget to use that "Request quote" button.

[egonotto]

Hello,

the SDS2104X HD is no longer available from Batronix.

Best regards
egonotto

[egonotto]

Hello,

it is now exciting to see whether it will arrive this week. I have not yet received any information that the SDS2104X HD has been in transit.

Best regards
egonotto

[Martin72]

... and neither from Batterfly. It's not "not in stock", but entirely unlisted. So maybe we understood tautech's hint right after all, and this model is being discontinued? But strangely, siglenteu.com still lists it at 1880€ excl. VAT.

This indeed suggests that the 100Mhz are being sold off.
Does that make sense....
I don't understand the strategy behind it, but I don't have to.
Someone should let Welectron know that the prices have dropped for the 2104X HD - they still have some in stock, but at the old price.

[H.O]

Interesting indeed. It vanishing completely from the Batterfly website was what I noticed the other day when I almost let go of the idea. Then it showed up at Batronix long enough for me to place the order and then dissappears again.
Have an order confirmation but it has not been shipped yet so I guess we'll have to see.

Siglent.eu still lists it but at €2682 and I assume that's +VAT since they list the bundle at 235 (which is the price +VAT at other places).
Siglenteu.com lists it at €1880.
Swedish retailer Elektrokit.com claims to have one i stock but at an even higher price than Siglent.eu (around €2800 (+VAT) at todays exchange rate).

[egonotto]

Hello,

I think it will work. It was still there on the night of 25.3.2024 to 26.3.2024.

Best regards
egonotto

[Martin72]

 

[fredo_]

It disappeared from Eleshop.eu too !  https://eleshop.eu/catalogsearch/result/?q=SDS2104X+HD
I received an email this morning from Jeulin.fr (where I ordered mine) saying it should be delivered by the end of next week... finger crossed !

[Martin72]

Why not, this is a very good scope that doesn't even have to hide behind the HDO6034A (in most areas, not all) and I congratulate anyone who was able to get hold of it at the last price.
But I would have rather expected the "ancient scope" SDS5000X to be taken off the market.
You can make mistakes like that.

[dexar]

According to one distributor that I talked to Siglent has discontinued the 100MHz model. The ones that are at sale is the current stock.

[Martin72]

Yepp, the 100 Mhz model has been discontinued.

[H.O]

Yes, I asked Batronix and they confirmed that the 2104HD is being discontinued.
With both the 800 and 1000 series having a 100MHz model I guess they felt there was too much overlap. But then, there's a 200MHz in the 800, 1000 and 2000 series so I don't know. Their decision of course.
Anyway, they also confirmed that mine shipped this morning.

[egonotto]

Hello,

I ordered on Monday but nothing had been dispatched by Wednesday evening

Best regards
egonotto

[Martin72]

Where, by batronix ?
Have you received any kind of confirmation at all?

[egonotto]

Hello,

yes, I received an order confirmation and a pro forma invoice and transferred the requested amount immediately.

Best regards
egonotto

[Martin72]

Already paid, aha...
Then they'd get in touch if it had already been sold out.
Otherwise, I would contact batronix again tomorrow if I were you.
I would write, I ordered the scope and paid for it straight away and now I can no longer see it on your site - can I still get it?
Or something similar.

[egonotto]

Hello,

I have written an e-mail to Batronix. I won't receive an answer until tomorrow.
In my opinion, I have a purchase contract with Batronix. I therefore assume that Batronix has reserved a device for me.

Best regards
egonotto

PS: It would just have been nice if I had received it by Easter Saturday

Just giving Frex's post a bump in case anyone can comment on the youtube video showing the performance of the X Plus vs the X HD for digital signals.  Is that because processing the 8 bit signals is easier than processing 12 bit signals or maybe the test wasn't done properly or something else?  Thx

Pay close attention to the fact that the devices are not setup the same. It's mentioned in the comments on the video too. There's also a link to the thread where it's discussed further here...and the video is 2 years old, so it's not even relevant firmware anymore.

KungFuJosh, thank you. 

from the comments:

"@voitano73
1 year ago
Plus is set to 1kpts timebase , HD model is 4Mpts"

this^ is what caused the X Plus to perform better than the X HD?

So bottom line, if the testing was set up properly and the newest firmware was installed the X HD would perform as well or better than the X Plus on the digital channels?  Or there is still some advantage for the X Plus?

Martin72 and others, thanks for referencing the thread but I don't see anything that definitely explains the performance difference.  I saw other people saying they had similar results to what was in the video and I saw the suggestion that there were setup differences and I saw that there might or might not have been a bug report to Siglent and I saw that there was new firmware - but I didn't see where (in the thread or anywhere else) the performance difference was ever refuted or definitively explained.  Sorry if I missed it.  Was there a clear resolution?  If so, maybe someone can please cite it?  Thx

[Martin72]

Martin72 and others, thanks for referencing the thread but I don't see anything that definitely explains the performance difference.

The link was also only meant to show that there was a discussion about it, including confirmations that the person who first noticed it did nothing wrong, because others could also reproduce it.
That's all there is to it, it came to nothing.
I bought a set of original logic probes much, much later and didn't notice anything detrimental during my tests.
Perhaps the update rate hardly plays a role in this case.
Or it was fixed in the last firmware update.
If there are any concerns, I would mention this again in the bug thread, it will get lost here.

Martin, thanks.  I posted here in part because I was thinking I might "need"   a 1000X HD or a 2000X HD rather than a 800X HD.  So just to clarify, I'm not trying to report a bug - just trying to understand a few performance differences (and discrepancies?) mostly between the 1000X HD and 2000X HD but also among some of the other down stream, up stream, and adjacent models.

To be candid, I might have developed a variant of TEA called "New Siglentitis" - which I think I contracted from trying to read all the HD posts and discussions around here - and now I'm very close to pulling the trigger on a 2000X HD.  But when I see reports that somehow the 800 and the 1000 outperform the 2000 and 3000 on the mask measurements, and maybe the 2000X Plus outperforms the 2000X HD on the digital channels I start to wonder if I'm too far out over my skis? 

Maybe I don't understand enough about the FPGA or other architectural aspects of the Siglent product family to make an intelligent decision.

For example, just above in this thread we have these specs:

SDS800X HD and SDS1000X HD
Mask test speed  Up to 80,000 frames/s

SDS2000X HD
Mask test speed  Up to 14,000 frames/s

SDS3000X HD
Mask test speed  Up to 28,000 frames/s

I don't really absolutely "need" all of the features or any particular specs mentioned but I'd like to at least make a good decision among the available models.

fwiw I have a 2000X HD sitting in a shopping cart but these last two outlier cases (mask speed and digital channel performance) are causing some cognitive dissonance.   

Maybe I just need to slow down and better understand the X HD line up from the 800 thru the 2000 series.  After a few weeks of reading/studying I thought the safe/preferred choice was the 2000X HD and I was ready to hit the go button but between the X HD mask specs and now the X Plus vs X HD digital channel video I am having "almost buyer's" remorse. 

That's my story and I'm sticking to it - but I'm open to therapy.   

[egonotto]

Hello,

I have the mask test speed data from the data sheets. I don't know whether this data is correct. I have found errors in data sheets from time to time. I also don't know whether the mask tests are equally powerful in different devices.

Best regards
egonotto

[tautech]

EF, nice post and it does seem unusual the Mask test rate is so low in the datasheet (just checked) compared with other models.
However there is probably a partial workaround for the more simple waveforms in that SDS2000X HD provides for 2 user definable Zone triggers where when strategically placed and a Not Intersect property selected, using this instead of Mask could maintain a higher framerate.

Not tested and none in stock but others might contribute/clarify.
 

[KungFuJosh]

I don't believe the 80,000 on the mask test. It's probably a typo.

[tautech]

No, 80,000 is what the docs say for the SDS800XHD. I find it hard to believe that a hardware accelerated function would be highest in the lowest model. That's not how hardware planning usually works. I also assume it was supposed to say 8,000.

Kindly, Please, don't put words in my mouth that I haven't said. I think the straw puppet theater belongs somewhere else - or not any - in my opinion, it is not suitable for anything.
     


SDS3000X HD max speed is stated as up to 28000/s and it is true least at current FW 1.0.3.3.

I also wonder where from come suspect or claim that it is not true.
Later when/if I have idle free time to take SDS2kXHD on board (if need) I can also check it.

With this test I measured ~28300 fail pulses/s from Aux BNC when test was continuously running as in image below.

My bad (even though it was posed as a question). 😉

Still though, it's crazy to me that a hardware based feature would have the best performance in the worst model. Hopefully it's a temporary firmware limitation, but even that is odd since at least the 2KXHD model has had plenty of time to mature.

[Martin72]

Hi,

Still though, it's crazy to me that a hardware based feature would have the best performance in the worst model.

According to the datasheets:
SDS2000Xplus, SDS800X HD, SDS1000X HD, SDS7000A: 80.000
SDS3000X HD: 28.000
SDS5000Xplus, SDS6000A: 18.000
SDS2000X HD: 14.000

So the 2000X HD is the best model of all.
However, I had never used the mask test to be able to judge whether the rate is really important in "real life" or only for data sheet fans.

This is still kinda confusing.

Not sure why these specs indicate the 2000X is ”the best model of all” (maybe it’s just humor?).
More importantly, while any one feature spec is just one feature spec - which may or may not be of interest to some users - this feature spec indicates that (unless it’s a documentation error) something is different about the architecture of the 2000X HD vs the product family siblings.  Maybe hardware or firmware or support or some other aspect of product development?

[KungFuJosh]

It was humor. Truth be told, it probably doesn't matter for most people whether it's 10k or 100k per second on a mask test; it's just the idea that they made more expensive models with a lower spec that I can't reconcile in my head.

roger on the humor

and yes this feature spec is not a big deal

just trying to understand the “why” and if there is any notable implication for the product (especially with respect to the support road map) beyond this one feature spec

it would be nice if someone from Siglent could explain it

Same, I'd like to know why. I can make some guesses, but there's no point in guessing. I don't think there's any real concern for the support roadmap for any of these for at least a few years.

Hi,

I would also be interested to know why this is the case.
That it is probably not a big showstopper, this thought came to me when I found the specification in the data sheet of the SDS6000A, after all the "most powerful" SoC oscilloscope.

Maybe the (older?) 2000X HD has some different (FPGA?) resources that encouraged the designers at the time to be more conservative in how they managed/allocated the resources, and at the time the mask "budget" only got what it got?  How much similarity/difference is there between the 2000X HD and the 800/1000/3000X HD?  Which leads to the question of whether the 2000X HD is on some different firmware dev branch than the 800/1000/3000 X HD?  Just pure speculation.  Maybe rf-loop, 2N3055, Performa01, TopQuark, mawyatt, tv84, tautech, et al / others can give us an overview of the the similarities and differences of the underlying architectures of these scopes, and some thoughts on how the hardware similarities/differences might impact future firmware development, upgrade rollout, and product support across the models?

I think you are overestimating the insights that the (basically three?) siglent beta testers have.
Even if they or some or at least one of them had this insight, it would be unwise to publicize it.
For most end users, this is also not interesting in the sense of what benefit they get from the knowledge apart from satisfying their curiosity.
Even if, as a technician, I naturally always want to know how something works together, I am basically only interested in one thing in this question.
Does it make a difference or not?

Might depend on how curious someone is or what they find interesting.

Their functionality and UI can be traced back to SDS5000X, which IIRC was the first to use the current UI or maybe discontinued SDS2000X ?

Which leads to the question of whether the 2000X HD is on some different firmware dev branch than the 800/1000/3000 X HD?

SDS2000X HD was Siglents first 12bit model and as such much served as a development platform in some ways however initially they were priced beyond the reach of the average advanced hobbyist and SDS2000X Plus was the cheaper and more favored model.
However now all latest Siglent DSO's essentially share the same UI, improvements and bug fixes are in time rolled out to all models.

Maybe rf-loop, 2N3055, Performa01, TopQuark, mawyatt, tv84, tautech, et al / others can give us an overview of the the similarities and differences of the underlying architectures of these scopes, and some thoughts on how the hardware similarities/differences might impact future firmware development, upgrade rollout, and product support across the models?

Typically all models use a dual ADC architecture, each with dual memory support but how they each might be configured can initiate confusion as they each have been configured in a way to meet their feature/price point vs marketplace competitors.
At this stage the only model that seems different is SDS7000A as Siglent have developed their own next level acquisition HW to properly compete with other brands that offer 2-8 GHz DSO's.

Hi,

Hehehehe.....
The 100Mhz model lives on, at least at Lecroy.

Maybe 14k was just a documentation error?
