Then you can only congratulate the future 1000X HD owners that they have a very good converter under the hood.
Are you still on vacation or can you already provide us with English data sheets?

Question was did anybody tried Bode plot and how was it performing and how was it to use.

I personally repeated (warned) several times SDS800/1000X HD do not include AWG and MSO hardware in the box.
But that was not the question, and nobody was hiding the facts..

I personally like to have scope cheaper few bucks and nix internal AWG that is limited in many ways, and save towards external fully featured AWG.
There are many advantages to that, if it can be afforded.

Exactly

Having an external AWG like the SDG2042X expands the DSO Bode capability considerably!!

[Martin72]

The SDS2000X HD is "dead" in terms of noise, it has a regulated fan inside.
Someone has to open up the case of a 1000X HD or report what he hears during the boot procedure.
Most fan controls can be recognized by the fact that the fan first reaches maximum speed for a short moment, then slows down.
Although I have to say that the uncontrolled fan in the SDS2000xplus was not quiet, it was much quieter than the one in the DHO4204.

[thm_w]

As tautech said in the previous thread, he believes they won't sell SDS1074X outside of China. So that is probably cheaper than any local dealer you'll find for SDS1104X HD (expect $1300 USD retail price).

But, yes probably some cheaper grey market sources will show up, and who knows they might change their mind if sales are poor.

The sellers from Alibaba have nothing to say about not shipping to Europe. The quotation I recevied from they was for shipping to Romania as I requested(aprox 140 $ shipping). This was in 20 Dec.

The difference in price from the 70 to 100 MHz model is less than $ 15 in China. I don't think that will affect the drawbacks of buying without support TBH.

If the price is $1300/€1200, then maybe it is worth the savings. If it is under €1000, I don't think so. In any case the difference in price between the two base models is peanuts, so it won't be a relevant factor, whether they sell the 1074 or the 1104.

On another line, and completely off-topic, Siglent seems to have released a new 34461a.
I mean SDM4000A  , 6 1/2 DMM with scanner card option, apparently user-swappable.
https://www.siglent.com/products-overview/sdm4000a/
EDIT: My apologies, the SDM4000A already has its own thread.

[Martin72]

I wouldn't worry about the prices in China, I think this speculation is pointless.
Likewise whether a 70Mhz will come or not, although I think the probability is close to zero, see the SDS2000Xplus series for the rest of the world.

No I doubt the price difference is less than $15... that makes zero sense.

Here is what you said "But I think it worth waiting for local dealers considering shorter time until launch.". There will be no local dealers for that model, that was my only point.

Have a look there, at the bottom of the page. 6580 vs 6680 Yuan. It doesn't mean anything for european pricing, just the fact that the existence of the 1074 is irrelevant for us, even buying from grey market.

Guys...
2-channel models: 586€, 689€, 727€
4-channel models: 842€, 855€, 868€
Does that make any sense?
Forget it and wait and see.

2-channel models: 586€, 689€, 727€
4-channel models: 842€, 855€, 868€
Does that make any sense?

As to see 6 models, to support and test before any FW updates

Prices changes as for the 2-channels model, any larger price increase.

So for the 4x channels model, I would simple release the 200MHz model only... lets see how this goes on 

As you look at the FW updates, not may seen so far for the old products (SDS 2K+,SDM, SSA)

I don't think they will release only one model. The base one in a hackable 'scope, is for hobbyists, the upper models and options add another source of income from education and enterprise. Market segmentation inside a product line is way too settled in to go away so easily IMO. It must work pretty well, generally.

[KungFuJosh]

As to see 6 models, to support and test before any FW updates

It's not 6 models; it's 2 models with different bandwidth limitations applied. 6 models would imply other hardware differences. The "model numbers" are just stickers on the front of the 2 hardware options.

[rf-loop]

Two more questions to those with early access to the SDS1000X HD (or maybe those who can read a Chinese user manual):

The datasheet mentions that 200 MHz are only available with up to two channels, and the scope drops back to 100 MHz with three or four channels active.

Let's take this first.

Please feel free to reference this source accurately before this becomes a complete mess. Now it is good to remember that two different versions of this SDS1000X HD series have been produced. So called old version (light case) and new version (dark gray case).
Now you can probably also find information with this model name all over the internet, and some of the information may apply to one and some to another version.

So please elaborate. Which datasheet exactly and where?


New (current) SDS1000X HD:
Sample rate (Max.)
One channel mode: 2 GSa/s,
Two channel mode: 1 GSa/s,
Four channel mode: 500 MSa/s

Old (obsolete) SDS1000X HD:
Sample rate (Max.)
One channel mode: 1 GSa/s,
Two channel mode: 500 MSa/s,
Four channel mode: 250 MSa/s  (as can see it was absolutely mandatory to reject BW)


Average and Eres.
Both are mathematical functions so right place is in Math.
In a good analyzing oscilloscope, real data must be available all the time. Now it is. You have available normal true acquisition data and same time also Average calculus or Eres calculus results or even both. 

[2N3055]

I am not sure what restrictions result from having ERES and Averaging as Math functions only. The fact that they take up one Math channel per measurement channel when used seems like a clear disadvantage. And I don't follow in which way it would be better to have them as Math function only?

I keep repeating that these math channels have complex math. So you can have ERES, Filter and FFT for one channel (and more) applied as a complex formula, all simultaneously on single math channel.

Using ERES as a math have you keep original data as sampled - so you can have original data and 4 different transformations....

You might want to run FFT on original data on 2 channels , an ERES in time domain on one noisy channel multiplied with other channel that has Average on it to calculate power... that would be 3 math channels.
You can have a sampled buffer (stopped mode) and apply math ERES after the fact, changing ERES depth interactively, until it is just right..

ERES and average as sample mode is global setting for all channels.  That limits you to what can you do.

I know that I mostly use ERES as math function for quite some time. And don't even use so much ERES because of 12 bit and low noise. You use it only when you deliberately want to filter out higher frequencies in signal, and not to work around scope own noise or lack of resolution.

These scopes also have proper vertical zoom too.

[Martin72]

Hi,
With my SDS2104Xplus, I was annoyed to have to "sacrifice" a math channel for average or eres, because the scope only has two and one is already gone.
Then there was the fact that you then had both signals on the screen, which was also annoying.
This was solved quite quickly with the "Hide" function.

When the 2000X HD came out, it also only had two math channels, but average and eres as acquisition mode.
I thought it was great not to have to use either of the two precious math channels for this, despite the advantages mentioned above, if you do it via them.
Well, now I have both.
The use of eres and average via the acquisitionmode also has a small disadvantage:
This then applies to ALL channels, but sometimes you don't want this.

[Martin72]

I don't think so.
The SDS2000Xplus has neither 4 math channels nor digital filters and the necessary memory management, precisely for limiting reasons.
The 1000X HD has these functions.

Edit:
User "idolclub" could post a few more pictures with the scope in action.
To finally answer the bandwidth question, it would be enough if he activates 2 (direct) channels at the same time, which is then shown in their infoboxes.
Then we would know one hundred percent.

[2N3055]

I appreciate the strong brand loyalty and the protective reflexes. I would appreciate even more if someone could answer my questions re. what the SDS1000X HD actually does...

In the meantime I found an updated Chinese datasheet, https://www.siglent.com/u_file/download/23_12_25/SDS1000X%20HD_Datasheet_CN01E.pdf. The "200 MHz in 2-channel mode only" restriction has disappeared; it was probably just a mistake in the earlier datasheet edition, carried over from the old 1 GSa/s version of the scope.

There is still no mention of ERES and Averaging as acquisition modes; but again, maybe that is just an omission in the datasheet. Given how close the 1000X HD is to the 2000X HD in almost all software aspects, I was simply wondering about the difference. Maybe when @idolclub comes back online he can have a quick look at the actual product.

EDIT: Found the Chinese user manual and convinced Google to translate the relevant section. Averaging and ERES are indeed not supported as acquisition modes, it seems; only Normal and Peak Detect are on offer. See the attached figure from the manual.

For context, in case you have missed it: I have just returned my DHO1074 and am eagerly awaiting the release of the SDS1000X HD, hoping that it will come at a price I can justify to myself for hobby use. Trying to learn as much as I can about that scope in the meantime.

Please don't take this the wrong way, but would you please stop with these comments about brand loyalties and protective reflexes. You are completely off with that to the point to start being offensive. It starts to bother me. It is completely uncalled for.

You asked for someone to confirm if SDS1000XHD has ERES acquisition mode. I don't know because I don't have scope nor crystal ball. So I'm not going to answer what I don't know. Since I have no interest in that particular scope, I'm not going to make further research. Sorry, cannot help you with that.

You also made confused/inaccurate comments on usage of ERES on math channels and asked what would the benefits be. I answered that, because I know it, and actually use it every day. I have not 1 but 2 Siglent scopes of this family as daily drivers and am very familiar how it works.

Maybe you would trust my facts better if they came from Rigol user?

We are trying here to give you good data so you can make educated decision.
I'm not trying to convince you anything. Just to help you make  purchasing decision that is appropriate for you.
What you buy in the end makes no profit to me in any way, one way or another.

Those little (humorous ?) jabs are not appropriate if people are trying to help you.
If you don't want help from RF or me or anybody else, please just say so. So we don't waste our time just to be insulted as we are trying to help.

As a more constructive answer to your other questions, I also have no idea as to general performance of the "black" SDS1000XHD compared to SDS200XHD, for same reason. I find speculating about these things waste of time. We simply don't know until someone gets their "mittens" on it.
But what I know, is that I would wait for "rest of the world" release before we pass judgment. When 6000 series came out, there was lots of confusion about models because China only models had several hardware versions that never came to rest of the world.

Also all this talk about BOM optimization is not exactly correct. BOM optimization is exactly that: optimization. Difference lies in what optimization criteria is prioritized.  You must understand that parts acquisition channel in China works differently than in West. Pricing is different, volumes are different. Many times it is not about cheapest possible parts, but about availability.  Also Chinese companies don't have to have 1200% profit on BOM. They are being run differently.   
So without very detailed insight in Siglent inside strategy and structure of how things are done, we cannot make any predictions of any value. I know I don't have those details, and I doubt many outside inner circle have..
Don't get me wrong, speculate away if that makes you happy, but don't expect to be close to reality.. You simply have no relevant data...

This!

( Is it even small disadvantage...    )

[2N3055]

Please don't take this the wrong way, but would you please stop with these comments about brand loyalties and protective reflexes. You are completely off with that to the point to start being offensive. It starts to bother me. It is completely uncalled for.

Sorry if I caused offense; I did not mean to. But maybe you don't realize how quickly one triggers responses which seem to "defend" Siglent products.

In the present case, I simply asked whether two particuar features were in the SDS1000X HD or not. The answer from you as well as rf-loop was "here's why what Siglent has implemented is good" -- without even knowing (or answering) what Siglent actually has implemented.

You also made confused/inaccurate comments on usage of ERES on math channels and asked what would the benefits be.

Where exactly did I do that?

Maybe you would trust my facts better if they came from Rigol user?

Look, now it is my turn to get annoyed. I am neither in the "Rigol camp" nor the "Siglent camp"; I am just trying to find the right scope for my needs. (And in the present case have already concluded that the Rigol DHO1000 is not it.) I think I have made it quite clear in  many posts that I don't take sides -- or at least don't take the same side always. But apparently that's not good enough -- "You are either with us or against us." 

We simply don't know until someone gets their "mittens" on it.

Right. And if you re-read my post #50, you will see that a simple answer from someone who has the scope already in their hands is exactly what I was hoping for.

Good. As I hoped it was not meant to be offense. But still I do inform you that I don't like it. It was uncalled for.
I was not defending or protecting anything. Simply stating facts.

I am not sure what restrictions result from having ERES and Averaging as Math functions only. The fact that they take up one Math channel per measurement channel when used seems like a clear disadvantage. And I don't follow in which way it would be better to have them as Math function only?

My math comments are a reply to this..

And you are again being adversarial.  You stated that my comment was "reflexive triggered response of defenders or Siglent products". How is that not a jab at someone answering to some of your questions.
And I rightfully asked what do you want. An answer from someone who doesn't use Siglent products or those that know it in detail?
If you think my answers are not truthful and are just propaganda, please let me know so I don't bother.... That is your right.
I didn't attack you. You attacked me, calling me names.

And enough of this Siglent/Rigol camp. I don't belong to any camps. When I was saying good things about Picoscopes I was accused of being Picoscope shill.
I was the one that asked BUD to stop with endlessly repeating stuff about Yaigol PLL problems on DS1000Z. But was also one of the people who have found, verified and demanded RMS bug on DS1000Z to be fixed. While one of my now blocked "friends" was attacking me that I should shut up and just accept that is not a bug but an "imperfection" and "in specifications" and I should shut up and questioning my "agenda". Luckily we persisted and Rigol finally fixed that one. And he kept behaving like that, constantly attacking me personally for anything he didn't like.
So I have a lot of "emotional baggage" when people attack me for no reason.
You must appreciate how I must feel like an idiot after spending 10 minutes of my time to write detailed explanation of how math works just to greeted by "it is amazing how fast one seems to trigger responses which seem to defend Siglent".  Yes, that "took a jelly out of my doughnut"..

As for your post #50, you must understand that no person will go 50 posts back and read everything you ever wrote on topic to get full context.
If I respond to post #64 it is going to be response to #64, unless you specifically referenced something in a post.. And I believe most people will be the same.
Sorry for misunderstanding if any was there.
 
Best,

[rf-loop]

So please elaborate. Which datasheet exactly and where?

I was referring to the machine-translated English version in tautech's post, https://www.eevblog.com/forum/testgear/siglent-sds1000x-hd-coming/. That datahseet describes the updated 2 GSa/s version of course; otherwise I would not have asked about the bandwidth restriction.

It's a little awkward when these are published a little too early and then peoples read these like infinite truth.

In addition, it should be emphasized that  these (early info picked-up data from chinese web sides) need read with big reservations.
Especially in a situation like this, where this model has been just released over older version.
(But naturally root reason is Siglent when they publish data sheet before enough carefully revieved.)

I have one definite opinion. These must be removed from distribution. Just so that these false notions don't circulate, which then remain around forever. There IS an error in that data sheet.

According to my understanding (read: my current knowledge), the correct one is this (for next generation, dark grey  "black", SDS1000X HD):

Vertical (analog)
Channel
4 + EXT (4CH Series: SDSxxx4X HD)
2 + EXT (2CH Series: SDSxxx2X HD)

Bandwidth
(-3 dB) @ 50 Ω
SDS1104X HD, SDS1102X HD: 100 MHz
SDS1204X HD, SDS1202X HD: 200 MHz

Flatness@50 Ω
DC- 10% (BW): ± 1 dB
10%- 50% (BW): ± 2 dB
50%- 100% (BW): + 2 dB/-3 dB

Rise time@50 Ω
(typical)
Typical 3.5 ns (SDS1104X HD, SDS1102X HD)
Typical 1.8 ns (SDS1204X HD, SDS1202X HD)
------------------
And this note: *1: 200 MHz in single and dual channel modes, 100 MHz in other modes is already removed from preliminary english data sheet because it was (and is) only true in 1st generation version SDS1000X HD. This note do not belong at all to second generation SDS1000X HD. But because this model is not released for western markets there is also not current english  data sheet published.



And simplified:

SDS1204X HD, SDS1204X HD (dark grey "black" version)

BW:  200MHz when 1, 2, 3 or 4 channels are used simultaneously.

[rf-loop]

Thanks, rf-loop. As mentioned above, I found the updated Chinese data sheet (Rev. E) in the meantime, and it no longer mentions the bandwidth limitation for > 2 channels. Attaching a Google-translated copy here; maybe Tautech can update his first post in the SDS1000X HD introduction thread when he is back home.

This is afaik, just reason why he have not updated it. 

[idolclub]

Two more questions to those with early access to the SDS1000X HD (or maybe those who can read a Chinese user manual):

The datasheet mentions that 200 MHz are only available with up to two channels, and the scope drops back to 100 MHz with three or four channels active. Is that really how Siglent implemented it? That would be a rather conservative approach.

Also, the dataheet mentions ERES and Averaging only as Math functions; nothing about these modes in the Acquisition section. Have they in fact restricted this vs. the 2000X HD, or is it just an omission in the datasheet?

Thanks for any insights you might have!

Hi,

In SDS1000X HD, the ERES and Average  do not exist in Acquisition modes, but are placed in MATH Menu.

[idolclub]

I don't think so.
The SDS2000Xplus has neither 4 math channels nor digital filters and the necessary memory management, precisely for limiting reasons.
The 1000X HD has these functions.

Edit:
User "idolclub" could post a few more pictures with the scope in action.
To finally answer the bandwidth question, it would be enough if he activates 2 (direct) channels at the same time, which is then shown in their infoboxes.
Then we would know one hundred percent.

10MHz Leo Bodnar testing with two and four channels enabled on the SDS1000X HD.

[Martin72]

Maybe yes, maybe no, who knows.
It is what it is and ultimately only a teardown including removed heat sinks can shed any light on this.
We already know the 2000X HD board without heat sink.

[tautech]

Thanks, rf-loop. As mentioned above, I found the updated Chinese data sheet (Rev. E) in the meantime, and it no longer mentions the bandwidth limitation for > 2 channels. Attaching a Google-translated copy here; maybe Tautech can update his first post in the SDS1000X HD introduction thread when he is back home.

I will when we have the EN release version in a couple weeks.

Until then attached is the older and now outdated earlier white model version.
As has been discussed the sampling rates are now improved with all channels active for the forthcoming black models.

[2N3055]

Many thanks for the answers and additional data, @idolclub!

I couldn't help myself and scrutinized the datasheet a bit more, comparing to the SDS2000X HD. I notice that the ERES and Averaging are no longer advertised as being "hardware accelerated", and assume that is the underlying reason for having to remove these as acquisition modes: Presumably the (global) acquisition modes are hardware-accelerated in the 2000X HD, while the Math operations are done in software, at least in the 1000X HD?

Maybe I am reading too much into this, but it is all consistent with the assumption that the 1000X HD -- while having similar CPU horsepower as its bigger brother, and hence able to e.g. support 4 Math channels -- has a smaller FPGA on board, and is hence limited in its real-time processing capabilities. Maybe the "fixed memory depth" option in the memory management settings had to be left out for the same reason?

If you take a look at that translated Chinese V2 hardware datasheet (the actual scope that is coming to EU), and compare it to SDS2000XHD there is some interesting data inside.

First, math is accelerated. In addition to FPGA acceleration there is a DSP block in CPU for just such occasions too.
FFT is FPGA accelerated, for instance.

One interesting number inside datasheet is Waveform capture rate... V2 SDS1000XHD has higher numbers that are in a ballpark with 2000XHD. Even faster a bit, because it has less memory. That certainly does not point out to a less capable FPGA..
Or does it? I don't know.
I guess we will know soon enough...

Tautech,

If you don't mind me asking, is there a reason for this datasheet here?

It is a datasheet to a scope nobody will ever see, that will only add to confusion, if you ask me...
It is not applicable to this scope in this topic... It is literally something else despite name being same.

There was enough confusion, speculations, flaming and all kinds of non-useful stuff in that original topic based on people being confused by specs..
I would rather we mark as "Do not use" all the versions of V1 d.s. in circulation.

If it is really important to discuss something I think it would be better to use an translated unofficial Chinese d.s. for actual hardware V2. That one might have errors (by virtue of not being official and officially released yet) but is at least addressing right hardware...
I personally would not circulate even that, until there is official d.s. by Siglent in English, but that is me..

Don't get me wrong, I'm not policing what you do, just saying..

Best,

[2N3055]

First, math is accelerated. In addition to FPGA acceleration there is a DSP block in CPU for just such occasions too.

Alright -- "software accelerated" is not to be sneezed at.   As mentioned, my guess is that the CPU capability of the 1000X HD is the same as in the 2000X HD, and that the Math capabilities (and speed) are the same.

One interesting number inside datasheet is Waveform capture rate... V2 SDS1000XHD has higher numbers that are in a ballpark with 2000XHD. Even faster a bit, because it has less memory. That certainly does not point out to a less capable FPGA..
Or does it? I don't know.

Not a slower, but a smaller FPGA is my guess. The lack of a built-in AWG and logic analyzer have probably saved some gates already, and I assume that Siglent trimmed some more functionality so they can get away with a lower-cost part.

Why else would they leave out fixed memory and ERES/Averaging acquisition modes? It's not the type of functionality one would deliberately disable in a lower-end model to differentiate the higher-end 2000X HD, but rather "deep in the datasheet" functions.

I guess we will know soon enough...

Yes, I agree with you (and Martin before) -- it's all a bit idle speculation. But what else is a hobbyist keen on a new scope going to do? I'm not good at waiting, it seems. 

Yeah, it all good fun, just not to take it too seriously...

[Performa01]

Scientific scopes from LeCroy never had any acquisition modes that would destroy the original sample data, hence not even Peak Detect (but sufficient sample memory instead). Average and ERES always have been math functions only.

Siglent, on the other hand, even though cooperating with LeCroy, used to follow different philosophies and offered Average and ERES as acquisition modes. Up to late 2016, these modes were barely usable, because they were only available with short memory like 14 kpts, strongly reminding on the memoryless storage scopes from Tek at that time. Starting with the SDS1202X-E, we got these acquisition modes with 1.4 Mpts memory, yet not HW accelerated. Even more important, these models don’t have 16 bit processing, thus not actually giving any resolution enhancement with either Average or ERES.

The SDS2000X Plus has limited resources, yet it has a HW-accelerated 10-bit mode, which is equivalent to ERES1.0 – and the internal 16 bit interface. There is no noticeable speed penalty compared with 8 bit mode, yet there are no FPGA resources left for generic ERES or Average acquisition modes. As a consequence, we finally got these as math functions, which has a number of advantages, even though it’s considerably slower; we can apply it only to the channels we actually need it, can combine it with other operations – for instance we could use average and ERES at the same time for the same trace.

The SDS6000 and later the SDS2000X HD have sufficient resources, thus providing both the HW-accelerated acquisition modes and the slower math functions for Average and ERES.

[2N3055]

Thank you for the excellent overview, performa01!

The SDS6000 and later the SDS2000X HD have sufficient resources, thus providing both the HW-accelerated acquisition modes and the slower math functions for Average and ERES.

So speed-wise, the SDS1000X HD implementation will be a step back, since it will offer the (slower) Math functions only, right?  I do understand that flexibility-wise, being able to apply ERES and/or Averaging to specific channels only is an advantage.

I appreciate the "LeCroy philosophy" of leaving the original sample data unchanged at all times, to be able to apply various analysis operations on them.  On the other hand, a lot of my oscilloscope use is not highly analytical, but interactive -- so I also appreciate Siglent's efforts to strike a good balance between analytical accuracy and fast interactive response. Offering two ways to apply ERES and Averaging in the SDS2000X HD is a great way of supporting both use cases. But I can understand that "something has to give" in the 1000X HD to meet cost targets.

On Keysight MSOX3104 I use Hi-Res a lot. It is 8 bit, noisy (1GHz BW), and no less than 5mV/DIV in hardware.

On SDS2000X-HD there is hardly need for ERES for interactive work, unlike 8 bits scopes.
Visibly, on a screen there is barely a difference.
SDS1000X HD are very low noise and 12 bit, and only 200 MHz nominal BW.
For slow signals, where you want to filter out high frequency noise you simply enable 20 MHz BW limit and that is it.
I actually very rarely use ERES as acquisition mode. It is of no use for FFT, and even with the vertical zoom, scope will produce very detailed, thin traces without ERES.
ERES helps more with scopes that have large BW, suppressing more of the noise in higher frequencies.

[Wintel]

Does the SDS1000X HD have AC50 ohm inputs?

[2N3055]

Does the SDS1000X HD have AC50 ohm inputs?

According to datasheet, yes..

[idolclub]

Does the SDS1000X HD have AC50 ohm inputs?

Yes. There is DC50R and AC50R.

[roy_eedreku]

This scope seems really good and seems like a much cheaper option compared to SDS2000x HD. Does it make sense to buy 2000xHD if I don't need > 200 MHz and I already have a 60 MHz external AWG? I am not sure if I would be using the MSO feature much and Bode plot would be covered by the external AWG.

Thank you for the measurements 

Conclusions: Much less spurs, as may the result of different used ADC and may also some better RF shielding 

Hp

[hpw]

In addition as for noise measurements as required to "scale for noise" as 1/rtHz normalization and
Y Axis as may dB related (dB / rtHz) or linear related (V / rtHz ... nV / rtHz as Log Y Scaled).

Otherwise we compare spectrum's, with reduced FFT bins, caused by the larger FFT size 

May easier to export the sampled data & all required averaged sample data to process them on the PC.

Or does one SDS1000x HD, SDS2000x HD or SDS7000A HD support such rtHz measurements /scalings?

[maxspb69]

The SDS2000X Plus (which I have) and the SDS2000X HD (which I saw on the video) have a rather slow response to the rotation of the encoders. I would not call their interface pleasant to use. You can rotate the encoder quickly, but most of the "steps" will simply be skipped by the device.
How does the 1000X HD deal with this? If the owner doesn’t mind, it would be very interesting to look at a video where the oscilloscope screen and a hand, rotating the horizontal and vertical movement knobs, trigger level knob, etc. would be visible. So that we can evaluate the responsiveness of the device to external controls.

[Martin72]

SDS2000X HD (which I saw on the video)

In "real life" I didn't notice any major delays when turning the encoder.
But I'm also not someone who turns like crazy and expects a 1:1 conversion.
The encoders on the HD are "better" in terms of mechanics/feel.
It's quite possible that the same ones are also used in the 1000X HD - why stop at the housing...

SDS1204X HD prototype. (white model)

All encoders are detented types and of a softer/smoother type than SDS2000X Plus.
Responsiveness can be described in just one word, sharp.

[maxspb69]

No one expects a digital oscilloscope to respond instantly as analog one. But the latest Rigol models have a much more responsive interface than Siglent. I won’t even talk about Keysight scopes, which are close to analog in response.

Question for Tautech:

It is now possible to order a new (black, 2GS/s) version of the SDS1204X HD from China . Should I do this now or maybe wait for the official release in Europe?

Actually, the response of SDS1000X is very slightly better than DHO 1000X. The difference is tiny but it can be feel.

[maxspb69]

I would take the SDS2000X HD to replace the SDS2000X Plus, but the lack of hacking capabilities and the lack of the possibility of even officially purchasing "options keys" in the country, where I am today  are stopping me from such a replacement.
Therefore, I am looking at the SDS1000X HD as a 12-bit addition to the existing one.

No, 1-2-3 weeks is the normal waiting period. I was not aware of the release date. Thanks for the info.

[KungFuJosh]

lack of hacking capabilities

Lack of what now? Not knowing how doesn't mean the answer isn't available.

[KungFuJosh]

I can totally understand that Siglent wants to keep the lid on the license scheme for the more expensive products, and that those in the know respect that. But the resulting approach of "You first have to show your commitment by buying an SDS2000X HD, and then maybe someone will let you in on the secret" is not for everybody.

The scope is a bargain without hacking it, and prices are supposed to get even better... so people complaining isn't particularly impressive. 🤷

[KungFuJosh]

I am not complaining -- just commenting on your mixed-message response to maxspb69 above.

There was nothing mixed about it. Ignorance doesn't prove or disprove the existence of something. The point was to hint at the fact that a solution does exist.

[Martin72]

You shouldn't make a purchase decision based on whether you can "crack" the device, because then you don't really need it.

[KungFuJosh]

Sorry, but the arguments from the Siglent crew are hypocritical.

You seem to be having your own separate conversation or something. You buy a scope based on whether or not it meets your needs and budget. And if you need to hack it to make it meet those needs, then it's up to you to figure out how. Nobody owes you anything.

None of us work for Siglent, we simply like their products.

[maxspb69]

Has anyone ever talked about the fact that someone owes someone something?

I know that HD hack exists, but it is not public, therefore for me personally it does not exist. And awareness has nothing to do with it.
I bought options keys for my RTB2000, but at the moment I don’t have the opportunity to buy them for Siglent and the problem is not at all a lack of funds. Therefore, when deciding to purchase an oscilloscope, I must understand exactly what I will get in the end. Having purchased the SDS2000X HD, I will not be able to get the capabilities that I need. Therefore, most likely I will not buy it. Unfortunately.

[skander36]

This is your personal opinion. For example I have 4 scopes at 70 MHz , all hacked. I wouldn't buy anyone if were not hackable.
Is not not about someone oweing something to someone but about the scope of this forum - helping/sharing.
Please look at the questions in the threads dedicated to each scope model: "Is still hackable?" sound many of them.
Ethical problem has been discussed many time here but the conlusion was that as long as you don't sell the hack or hacked scope is ok for hoby use.

[KungFuJosh]

This is your personal opinion.

Nah, it's everybody's opinion, including yours. The difference is, hackability is one of your needs, and thus a requirement. 😉

So what are you telling me? You're don't feel like doing your own due diligence before purchasing an excellent product, so you'd rather do nothing? Are you assuming you couldn't return the product if you weren't able to "improve" it as you want to?

Your logic doesn't make any sense to me. You know the "improvement" exists, but you won't put any effort into making it happen? 

[skander36]

Pictures from the inside of SDS1000X-HD.
The ADC's are the same as in SDS2000X-HD which is capable of 2 GSas/s single channel and 1 GSas/s dual channel.
The structure inside is the same as in SDS2000X-HD except the mainboard.

[skander36]

Yes I know I am not a good photographer
You can say it ...

[skander36]

Many thanks for the pictures, and bonus points for removing the heat spreaders and thermal paste to show the key ICs! 

What is the little coax connector in the first picture in post #109 for? Test point, future option, or was it connected to something?

It is present also in 2000X-HD, it links to the backside connector board.  This board is also connected with a FPC cable so I don't know for sure what is his role. Maybe for
external trigger ?
I didn't take the pics from that board so I will use Dave's teardown of SDS2000X-HD which I said that its contruction is identical with the exception of mainboard.

[Martin72]

The ADC's are the same as in SDS2000X-HD which is capable of 2 GSas/s single channel and 1 GSas/s dual channel.

I had already guessed that they were the same - so they're not bad converters...
We already know from the Rigol DHOs that the sample rate can be different with an identical ADC configuration.
Didn't that have something to do with the FPGA?

[skander36]

Didn't that have something to do with the FPGA?

For sure! There is the place where the signals are processed.
The explanation for using the same ADC's maybe is in the price (8-900 E for 10 pieces). So they aquired large quantities to obtain a good price and planned from the beginning to use it also in the future versions.
Also the reason for not being configured in dual 2 GSas/s as in 2000X-HD is probably to not affect sales of this.

[skander36]

All it's possible. It is hard to know from the outside.
But given the difference between hardware of 2kHD and 1KHD I'm impressed of SDS1K-HD can do without signs of exhaust.

[Martin72]

Either that, or it's an artificial limitation introduced to protect the 2000X HD.

You can find out as long as skander still has his scope open...

It is already closed.
I am curious if the 3000X-HD will have the same HW configuration as 2000X-HD. It seem to be overpowered with 4 FPGA's.

[switchabl]

Looking at the photos, memory is 2x Samsung K4A8G16. That's 16Gb DDR4 with 32 bit bus and I'm assuming 2400 MT/s (maximum the ZUS+ controller can do), so 9.6 GB/s max. But that's peak bandwidth and it is shared with the ARM cores as well. So in practice 2x2 GSa/s is going to be hard to pull off.

The DDR controller supports up to 64 bit width, at least in the larger packages. So there is some potential to further scale up this architecture.

Memory configuration on the 800HD looks to be the same (except it's only 2x4Gb).

[Martin72]

I am curious if the 3000X-HD will have the same HW configuration as 2000X-HD. It seem to be overpowered with 4 FPGA's.

I don't think so.
If you look at the data sheet at certain points, the 3000X HD is closer to the 6000pro H12.
Just the fact that it has +4bit Eres (to get to 16) instead of the usual +3, as well as double FFT memory, 1GSa/s logic analyzer (instead of 500MSa/s), USB 3.0, etc., suggest that it is a little brother instead of a 2k HD on steroids.
I will know soon, but I will not unscrew it.

[skander36]

Then maybe Dave will get one 

[Martin72]

That would be better, because unlike him, I have to pay money to get one.
In 8 days there will be a launch of three new model series of a popular brand, which would normally be a day of celebration for YouTube reviewers like him.
But I have certain doubts that he will be suitably delighted with test models from Siglent.

siglent.eu is a retailer and has nothing to do with the official site of siglent europe..
But if he names the prices so shortly before the launch, then they are probably true and therefore the 200Mhz 4-channel is even cheaper than the 100Mhz 4-channel from rigol.

...their siglent.eu domain is clearly misleading potential customers.

Yup, same with https://siglent.co.uk/ is actually owned and operated by https://telonic.co.uk/.

The Siglent mothership should have control of all these domains and list disti's on there as needed. Rigol also has a similar sh*t show, with confusing firmware distribution as a result.

I think that AllData (Italy Rigol distributor) has the correct approach: the site could be misleading https://www.rigolitalia.it/ , but in the main home page logo and in the footer is clearly stated that they are a distributor

For about 10 days I'm running on Fw. ver. 1.1.3.1. on SDS1204X-HD.
This Fw. was send to me by Siglent support as non final version to solved 2 issues that I encountered with SDS1000X-HD.
One was incorect render of the waveform when zoom on the captured signal that looks with semicircles as attached.
Now, with the new Fw. the signal is show corectly as it should on max zoom (second pic). Problem solved.
The other was a bug that make the scope to remain locked on the PSRR measure function in Power Analysis. You can restart but to access any application from Power Analysis menu you should restore to factory defaults or do a security erase, because it remained stick with the PSRR (the Bode plot app which is used in this test does not exit correctly and remain stick). Also this problem was solved.
I have no other issues with this Fw. until now. It is possible that the 1000X-HD models that will be delivered soon to already have this version or newer.
A few more pics from the inside.

Some time ago Dave made 2 youtube video's about the SDS2000X+ memory management (which caused a lot of debate). One about the history mode which was constantly engaged and one about the inability to zoom out on a screen capture. If I understood correctly, this behaviour was changed for the 2000HD series but never for the 2000X+ because it isn't possible or Siglent doesn't want to change it for the 2000X+.

How is this behaviour for the 1000HD series? I am considering to buy a 2000X+ but the 1000HD is also an option for me.

The behavior seem to be the same as SDS2000X+.
The history mode I found always on, even if I turned off.
Also the scope is capturing only what is on the screen, even if I allocate 100 mpts. If you want to zoom out you can't. But if you need more data you may set the timebase to a more larger value, allocate entire memory and you will get enough data. For my needs this is ok but I can understad if there are situations where this is not the best scenario.
