content: 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.

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.

content: Quote from: thm_w on January 11, 2024, 12:52:36 amThe 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.

Market segmentation inside a product line is way too settled in to go away so easily IMO. It must work pretty well, generally.

content: Quote from: ebastler on January 13, 2024, 08:26:45 amLet'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/sOld (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.

content: Quote from: ebastler on January 13, 2024, 10:12:06 amI 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, allsimultaneouslyonsinglemath 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.

content: 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.

content: 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.

content: Quote from: ebastler on January 13, 2024, 11:14:15 amPlease 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...BestSinisa

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,

content: Quote from: ebastler on January 13, 2024, 10:12:06 amIt'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)Channel4 + EXT (4CH Series: SDSxxx4X HD)2 + EXT (2CH Series: SDSxxx2X HD)Bandwidth(-3 dB) @ 50 ΩSDS1104X HD, SDS1102X HD: 100 MHzSDS1204X HD, SDS1202X HD: 200 MHzFlatness@50 ΩDC- 10% (BW): ± 1 dB10%- 50% (BW): ± 2 dB50%- 100% (BW): + 2 dB/-3 dBRise 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 modesis 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.

content: Quote from: ebastler on January 14, 2024, 10:37:13 pmIf 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...

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,

content: 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.

content: Quote from: ebastler on January 16, 2024, 03:10:10 pmOn 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.

content: 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.

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).

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.

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.

content: I just got my SDS1204X HD, and while testing I noticed unresponsiveness of the ch1 and ch2 buttons. Then in keyboard test mode the keys were also unresponsive.After a while with fiddeling around with the keys they became responsive, it was almost like there was some dirt on the pcb or something and the fiddeling made the contacts clean enough to work.My previous scope was a fluke pm3094 and after many years of service no mechanical problems, but siglent is a hole different level of instrument. So is this normal for an instrument of €1400? Should I send it back on warranty?

So just the memory storage, and waveforms/s ?How does the 1104X HD cost almost 3x the price of the 804X HD (I know the BW is 100 vs 70) ? The 1104X HD is still about ~2.5x the price of the 814X HD, here in Canada anyways.I'd really like to see these scope side by side, but I'd say the 804X HD will be fine for me for now.

Now at the time i was just doing a comparison with a Micsig MHO14, and that casing runs quite hot while in operation, so i might be making an unfair comparison here. But maybe the fact that the case was (too?) cool indicated that the fan had failed and then something overheated causing a short? It was running for maybe 30 minutes or so before dying. I dont know how warm the SDS1000X HD casing is supposed to get, so its speculative from my side.Do siglent scopes have overtemperature or fan failure protection?

For as long as I can remember, every processor has had internal temperature sensors that throttle the CPU or shut it down completely if the temperature gets too high.In your case, however, I think it's more likely that the power supply has suffered “sudden death.”

It just turned on without issue.I dont know what to think of that...? So Eleshop assumed it must have been the powercable i was using, and decided to ship the scope back to me.Err, well... if they would have asked me i could have told them i had already tested the power cable (obviously...). The cable is fine... At least it works fine in all my other equipment.So at least one thing we learned here is that it wasn't a catastrophic failure. The scope still works (for now). So it must be an intermittent failure is my guessing? Maybe a contact issue that got resolved by transport? Anyway, i'll see what happens when i get the scope back. But my gut feeling tells me the issue isn't resolved and the scope will be returned for repair again in the near future...

So to now have it fail multiple times in a row because i wasnt inserting it properly doesn't make sense. I don't know, maybe there was a tiny obstruction inside or something...?Anyway, ill do lots of testing in the coming weeks, see how the scope holds up.

Lets hope that's all it was this time.An anectdote, which I've told here before, but worth telling again:Many years ago now I bought a HV diff probe from Pintek (not Pintech). During testing it constantly showed twice the voltage compared to my FLUKE 89 DMM so I contacted them and, as is usually the case, they'd "never heard of such an issue", but they express shipped me a replacement probe. It arrived, I connected it in place of the original and it was exactly the same issue - at which point it hit me. I had the FLUKE across positive and ground while I had the diff probe across positive and negative of my dual output tracking supply. Both probes worked just fine.I owed up, shipped the replacement probe back at my expense and asked how to reimburse them for their expenses but they just thanked me for telling the truth of what actually happened. Love it.

I inserted the SD card with the system, powered it on — and nothing. The LED didn’t light up, power consumption was minimal, just like the device was completely off. I pulled the card out thinking maybe it would try an online boot like the Raspberry Pi 4… but again, total silence. I tried to insert card again with no result. So I was almost convinced I had received a defective unit, especially as I bought it with a small price discount. I even wrote up the dispute text, recorded a video, got everything ready to open a case. But before doing that, I decided just to try another SD card. And it booted right up. Turned out the first card had simply died for unknown reason (it was pretty new) and wasn’t readable at all, and it appears there’s no online boot on these Pi versions and LED doesn't light on power on before OS boot. So instead of opening a dispute, I ended up thanking the seller.Glad to hear it worked out well for you too!

content: Hi GuysI could barely read the frame rate on the screen via VNCViewer, either via the web or via the Windows software, which was between 7 to 9 FPS. This is very low. It should be at least 15 to 20 FPS. The connection speed is close to 100 Mbps, which is 8 MB/s. Based on this information, I tested with several different software, all of which were very slow. Now if there is a way to increase the frame rate, fix this in the future because this delay is also not desirable for recording and displaying on the monitor.Thanks

content: Quote from: KAKUL on September 22, 2025, 05:25:43 pmConsidering using libvnc 0.9.12 I checked a few open source servers and came across TurboVNC and a few I will mention here. The information shows that the current server uses ZRLE and Hextile, both of which are inefficient compared to Tight encoding (used in TurboVNC). Tight encoding in TurboVNC can reduce data transfer by 50-70%TurboVNC reduces CPU consumption with its lightweight design and advanced optimizations (such as pipelined updates and dynamic resizing), while libvncserver 0.9.12 introduces more overhead due to its older architectureUsing TurboVNC significantly reduces bandwidth requirements and increases FPS in desktop/graphics rendering compared to ZRLE/older libvnc — especially on ARM hardware (Zynq ZU2CG) that has the efficiency of SIMD-accelerated code (libjpeg-turbo, zlib-ng)I recommend using TurboVNC instead of the current x11vnc/libvnc for remote desktop service on Zynq (ZU2CG) devices.Technical reasons:1) TurboVNC uses JPEG compression (libjpeg-turbo) and zlib-ng optimizations, which are ~25–30% faster on ARM2) Its interframe/shadow framebuffer mechanisms significantly reduce network traffic

content: Thank you for this detailed suggestion.Let's wait and see if Siglent will consider it. I for one fully support the idea of using better compression algorithms in order to get the maximum out of the given LAN bandwidth.In any case it probably won't happen very soon, as Siglent R&D has a lot of workload and speeding up the webserver certainly isn't high on their list.

content: Quote from: Performa01 on September 23, 2025, 08:00:20 amKakul suggested VNC version that uses lossy compression (JPEG) and is optimized for speed over image quality. Also it is questionable if current update speed is limited with VNC implementation or by assigned application priority.We must always remember that oscilloscopes have hard realtime parts that take absolute priority.

content: Quote from: 2N3055 on September 23, 2025, 08:45:09 amYes, you're right of course. Yet more/better compression is still the right direction to go. For the relatively low complexity of a DSO screen, a better lossless compression algorithm such as PNG should be possible and realtime processing could be faster than any JPEG.

content: Quote from: 2N3055 on September 23, 2025, 08:45:09 amI don't think they intentionally slowed it down because it's inherently slow due to the old version of libvnc and ZRLE.If we assume that the waveforms and measurement section are an animation, they are always changing.ZRLE is not optimized. It is suitable for images with few changes (such as simple user interfaces), but in the previous example it is slower in changing waveforms and measurements.ZU2CG uses two Cortex-A53 cores (AArch64) — this architecture takes advantage of SIMD/NEON and is better synchronized with libjpeg-turbo and zlib-ng, meaning TurboVNC actually works better on this chip than older implementations.

Question if there are resources available for this (both in development and in hardware resources of all of the scopes in question) only Siglent can answer.

content: HiThere is a point about the ADC temperature, which is about 50 degrees. I think this temperature is too high. The appropriate temperature is 40 degrees. High temperature will cause noise. The default installed fan cannot transfer air pressure from outside to inside and remove heat. There are two ways: one is to replace the internal fan and the second is to add a fan next to the air inlet on the left side of the device. According to the pictures shared by Dave, if a thermal pad can be placed on the ADC heatsinks and attached to the top of the case, it can transfer some of the heat to the case. Friends who have already opened it, please try it with an oscilloscope if you are willing and please tell me the result.Thanks

content: QuoteThere are reasons why the temperature readings are not accessible to the (end) user; they could make them nervous for no reason.I extracted all graphs with temperature-dependent curves from the data sheet.DNL, SNR, THD, SFDR, ENOB.As you can see, there is no cause for concern or rework.In other words, it can be assumed that the developers at Siglent are also familiar with the ADC data sheet and have adapted the design accordingly.There is always room for improvement, but the question is whether the benefits justify the effort.This is a question that all developers ask themselves every day.Martin

Cars, ships, planes would have no electronics that doesn't die all the time.Or it is you that is pulling arbitrary statements out of thin air..And my response to you was not insulting..And I do have many details and informations. I am just not sharing it with you in the public forum.I did review thermal design and found it very good.If you asked politely why I think so maybe I would have explained a bit.Now, I couldn't care less.

Just direct, without false pleasantries.You proceed with insults and generalizations."I always do...." What are you, my case officer that analises all my responses and have statistics?Is that is also coming from the same scientific process that says semiconductors die at 50°C?If you have problem with communicating in foreign language say so.We'll sort it out.Escalating with insults is not answer to any problem. It IS the problem.I still stand (and with so many industry wide references that I am not going to bother to cite because it is not needed) at my factual statement that declaring that modern ADC running at 50°C is "too hot" is ridiculous statement. Whoever told you that is wrong.Open datasheet for the ADC in question and you will find it there.If you want to make such grandiose statements, than it is YOU that did not provide ANY proof or demonstrated any resemblance of "scientific process" that resulted in that claim. If you can demonstrate, by scientific process, by manufacturer datasheet or errata sheet, their written statement or something, I stand corrected and will formally apologize to you, right here on forum. I admit when I am wrong and pay my debts.If I insult you for telling you the truth, than that is YOUR problem.

He respectfully appreciated your previous comments, as he stated there and in response to your other statements. He is correct, in stating 50°C is nothing of concern for these chips. If you read the datasheet, 50°C is the middle of the smallest range. 100°C is the peak of the smallest range.It's okay to be wrong sometimes; don't take it personally.Thanks,Josh

content: I knew it! I wasnt going insane earlier when i posted that my SDS1104X-HD had died! If anyone recalled that i posted about this 4 weeks a go? Anyway, the scope got returned to the seller. They tested it, it was working fine on their bench, so they shipped it right back to me. Making me think that i hadnt plugged in the IEC cord properly or something...And sure, when i got it back it worked fine for a couple of weeks.BUT TODAY THE PROBLEM IS BACK!!!And this time i have some video proof!Something is not ok with the power supply of this thing... Its making some weird crackling and sizzling noises. Don't know if that shows up on the video or not.Sorry for the bad video orientation, i just got the phone out and started recording.Anyway, this thing is going back to the seller again!

content: It still looks like contact problems at the input, which would also explain the noises described (which I didn't hear in the video).To find out whether the problem lies with the plug/socket connection, you could proceed as follows.Take a conventional 3-pin power cable and crimp AMP cable lugs onto one end.Connect these to the contacts of the Siglent power socket – ensuring that the power is off, of course.This definitely creates a solid connection, but when the effects set in, there is a loose connection inside the scope.

content: Quote from: Martin72 on October 02, 2025, 09:27:40 pmThe high pitch arcing sound that i hear when the power led does light up temporarily is coming from the inside of the scope, somewhere near the powersupply.So i tried your suggestion (sort of) and hooked up a set of cable clamps to the IEC connector. These are fairly high quality hirschmann clamps with quite a bit of pinching force. So im pretty sure the connection on the IEC terminals of the scope is adequate. But still, the problem remains...That pretty much rules out anything outside of the scope, and the problem must be internal.I also checked the mains voltage, and sure, no problems there...

You never know if its something a bit more serious like a transformer arcing over or something.Ive contacted the seller, they already provided a return label for shipment and the unit will be replaced. Based on the video they could tell this was a very clear case for DOA / replacement.

And probably Siglent wants it back for failure analysis. They take QA seriously. They will want to know what happened here, because it is failure I never heard off before with them.Anyways, your patience paid off, and it also shows the value form buying from respectable vendors.Hope it will be smooth sailing from now on..Best,

And then on Sunday, it just turned on again, no issue whatsoeverI ran it all day to see if it would act up, but nope, working just fine. Maybe it got scared that it was going to get scrapped for parts... I kind of felt bad for the poor scope... It just wasn't meant to be...
