POI. Not all Digital issues could not be replicated by beta testers. The dual decoding fault is a recognised bug and is to be remedied in coming FW. There are to be 6 models in this range, 70, 100 and 200 MHz, 2 or 4 channels.

[@peterrenolds258]

Just bought the SDS814X HD largely based on your demo. Thanks so much for your detailed walk-through which now forms a large part of my instructions. I'm very impressed with the added capabilities over my old but trusty HP 1742A! I needed to capture stepper motor step pulses during motor acceleration and the memory depth and zoom capability made it amazingly easy to see the step pulse period changing from ~500uS to ~50uS. Still figuring things out but am very very happy. Looks and feels like a much more expensive tool. Have not figured how to set time and get it to stick, it just reverts to 1970... that's the only bug I've found so far. Installed the Feb 23 firmware update and it loaded flawlessly. Love it! Cheers

[@SurvivalSquirrel]

I was excited like you in the first few days. Until i found quite a few bugs. First i thought it is much better than the rigol. But it seems the Siglent bugs were just a bit more hidden. I dont know. There is one huge bug: the trigger holdoff is not working.

[@tautech8196]

@@SurvivalSquirrel A fix for Holdoff and other bugs is coming soon. We beta testers will have it this week and if all is sorted it should be available for the public quite quickly. Hang in there.

[@inakiteira6612]

Hi, may I ask where you bought it? Ive been checking Amazon or Ebay for the sds804x, but it seems as the only model available is the sds814x.

[@tautech8196]

Sorry Peter, I case you didn't know you require a LAN connection to have access to a NTP server to get actual real time. You can set all this up in the Time/Date menu. The scope should sync with the NTP server for the correct time within a minute or 2 of boot.

[@tautech8196]

@@inakiteira6612 Mine that Defpom looked at came directly from Siglent a few weeks before release. They are currently in high demand so keep looking but I suspect it might be a while until there is spare stock of these to pop up on eBay or Amazon. TBH you would be best advised to get one from a local dealer. Consult the Siglent websites for your local guys.

Thanks for this review / guide to how this works. Just starting to learn with my "824" I received last week. Very impressed so far.

[@danielmorgan7702]

This is a great video of a demo of a Siglent SDS800X HD series oscilloscope. Thank you! I watched this video when I was considering the scope. And now with the scope on my desk, I am watching the video again to better understand what features are available and how to get to them. Easier to watch a video than read dry documentation. I can read the documentation for more specifics.

[@markbratcher9095]

I'm holding out for the Rigol DHO814 vs Siglent SDS814x HD shoot-out. :) It seems Siglent waits for what Rigol is going to put out there, then a few months later puts out a product that is competitive in price for the same basic features (number of channels, bandwidth, etc) but exceeds in other specs and capabilities. But it's hard to compare their datasheets side by side.

[@david300m]

Very informative. Thanks for the effort.

[@weirdboyjim]

Nice review thanks! I have the SDS 1202X-E but a couple of times 2 channels has felt like a restriction so I’ve been looking for a 4 channel scope. This looks like it might be a smooth upgrade. I do make frequent use of the Ext input though, for many of my tasks it’s close to having a 3rd channel.

[@QsTechService1]

[@thierryj5035]

This seems to be the Siglent answer to the new low cost Rigol with 12 bit resolution. Why not to mention it ? But, as we still do not know the price of this thing, we cannot judge. Thanks for this review.

[@anorthernsoul153]

Great review! Looks like a really capable scope. Does the power analysis feature need a license to be unlocked?

[@TheDefpom]

I believe so yes, it’s listed as an option on the box of this unit, I’m sure you could “unlock” it yourself though soon enough, worth a look on the EEVblog forum to see if there are hacks one the unit is released.

[@TodoInventosTV]

[@stevehn787]

Just been out to see Rob tonight looking at spectrum analysers, he reminded me of your channel so here having a look. Rob sure knows his stuff, and can kill hours out there looking at all the products.

[@kevinjoyce5076]

As hobbyists we have never had so much choice and performance. Thank you Siglent. As the sample rate halves on channels 1 and 3 I assume there is only a single ADC in here, like the SDS1000 X-U. Is this the format across the range or will Siglent do a twin ADC version to mirror the SDS1000X-E? Whatever it all looks very nice. And well done on getting a review out before EEVBlog who's passion now seems to be pool cleaning robots.

[@tautech8196]

The SDS800X HD range all offer 2 GSa/s therefore with all channels active, sampling equals that provided by the 4ch SDS1000X-E series.

[@originalmianos]

NTP servers have a domain name as the name resolves to multiple addresses for fault tolerance and load balancing. You can probably enter a domain name in the box anyway, and you should.

[@tautech8196]

However Siglent models that support NTP require the URL of your local NTP server which can be found in seconds with a online search. NTP can be a one off sync or periodically as you wish. See the app note for X-E models: siglentna.com/application-note/datalogging-with-the-four-channel-sds1000x-e-oscilloscope-models/

[@originalmianos]

@@tautech8196 Seems to be an IP. in this app note, not a URL. I guess if you do have a local NTP server and the address is hard coded this is fine. If you are using an NTP server outside your own network you should be using a DNS name. How I know? Worked at at cloud provider. Built an proper NTP client for an MCU (Not a simple polling but actual NTP, that takes into account the delay and jitter).

[@BirdManPhil]

Am I wrong thinking this scope has a 16 channel LA input?

[@TheDefpom]

yes it does

[@bblod4896]

Nice. I still prefer my analog scope.

[@SirMo]

Analog scopes are fun to use. Also they tend to have the XYZ mode which can be quite handy and it's something that newer scopes don't have. I have a little curve tracer box that interfaces with the scope via XYZ mode. So I keep an analog scope around for this reason.

[@richardmerifield3263]

It looks identical to my old SDS-1104X-E but 12bit and touchscreen. The price will need to be the same or less than the old technology or it will be a hard sell in my opinion.

[@tautech8196]

Yes, this is the first impression until you spend some time with these new HD DSO's. Many more features and substantially more memory depth. The new UI aligns with the more expensive upmarket models.Being able to use a mouse with it is a significant advantage although Defpom didn't demonstrate it. Pricing is attractive. As yet not tested however I believe the cheaper 70 MHz model will challenge SDS1104X-E BW -3dB point.

[@richardmerifield3263]

Ok, thanks for the reply. I guess as a hobbyist there are only a certain number of features I need and nothing was shown that would add value for me. UI changes and a mouse would not warrant an upgrade, 12bit and touch might. I will keep an eye out for the many reviews likely over the coming months.

Twice the depth of the Rigol DHO800 scopes, no VESA mount and no HDMI output. It'll have to be a lot cheaper than the DHO800 to get any substantial market share

[@TheDefpom]

I don’t care about VESA mount I don’t have space to mount an arm, I have no use for hdmi, if I want a bigger view I can just use my computer and login to the web interface and even control it from there, and depth makes it more stable on the bench

[@yannis92preloude]

The price of the Rigol DHO800 is very good. You also have USB-C so you can run the scope on batteries which is very good. The Rigol is slimer in size as well, I have the 2CH Siglent SDS1202X-E which is a very good scope but now I would need to get a 4 channel scope 12bit will be nice but I don't know which one to go for Rigol or the newer model to mine. I would like to stay with Siglent but they are a bit expensive.

[@danielmorgan7702]

I disagree. I paid more for my Siglent SDS814X HD. I do not need VESA mount. I have a shelf to put my scope. And if I want to see the screen on my 27" computer monitor, I will just my web browser to connect to the web server on the scope. I decided against the Rigol DHO800/DHO900 series scopes because of all the bugs and how bad the lines look on their screen.

[@RodrigoForrequi]

I have a DHO914s and I'm considering bought a SDS814X HD. The Rigol interface its bad. They waste too much space on the DHO screen with non important things, like logos, draws, etc. Some people like and need the scope to be aside, so the Vesa would be a nice option. But the measurements results on the right of the DHO screen consume too much screen space, and the screen isn't big.Rigol put icons, draws, and some non sense stuff on a small screen. The DHO still have annoying bugs, freeze to much (I need to press Default button almost every use). I like the way Siglent does the measures results and other things. Even without the embedded generator I'm considering the SDS814X with care and attention.

[@danielmorgan7702]

@@RodrigoForrequi The siglent has an optional AWG you can buy. However, I am unimpressed with the built-in signal generator to the Rigol scopes and optional signal generator for the Siglent scopes. Just my 2 cents, you are better off getting a stand alone arbitrary waveform generator. Even if you have to go cheap and get a cheap Chinese $100 AWG Off ebay. Unless you want to do something like a Bode plot, then that might require a Siglent AWG to go with your scope unless you can figure out a way for your Siglent scope to control your non-Siglent AWG.

I've had a Rigol DHO814 since October now and I bought it as a second scope mostly because of its form factor. Sadly the Siglent design looks dated and very low cost. A missed opportunity I think.

[@tautech8196]

@sergivaschenko DHO has half the memory depth of lowest model SDS800X HD and half the FFT points: 1M vs 2 Mpts. This is all in the datasheets......

[@tautech8196]

@sergivaschenko Not so. You have full control for accurate FFT or fast FFT, entirely the users choice as it should be.

[@TheDigitalAura]

The processing speed of the Rigol is quite simply outstanding. The FFT must be the best and fastest at this price point. I've easily determined a keyfobs frequency using it, and there is no slowdown no matter how many other windows you have open.

[@John.Doe.2025]

Whooow! That's the huge advance. With new device You got 72 db floor on FFT instead of 48 db. If someone mess with digital signals only - just spend a $5 logic analyser on Ali.

[@tonyh6309]

​@@John.Doe.2025 Whilst the 12 bit ADC has lower noise than the 8 bit (Siglent spec is around 8.5bits ENOB) it's unlikely to be close to 4 bits better (I'd guess 6.5 to 7 bits ENOB for the 8 bit ADC). Also, note that the FFT noise floor is *not* the SNR of the ADC - the FFT has 'processing gain' as it is breaks the signal bandwidth into many narrow bandwidth bins. The longer the FFT the lower the noise; eg. a 4096 point FFT has a noise floor 33dB below that of the ADC. See Analog Devices MT-001 page 6 for an explanation.

[@veegee24]

Sadly, UI is still as laggy as it was 10 years ago. Seems like they don't really know how to write software. The whole thing stops acquiring and freezes whenever you interact with the UI, especially any of the horizontal and vertical knobs. Looks like the Keysight Megazoom series are still the only viable option if you don't want to get disrupted by a garbage UI.

[@danielmorgan7702]

The scope works for me. Most people watching this video cannot afford a very expensive scope from Keysight. This scope brings the high end scope features to a low end scope under $1000. And some compromises had to be made to get the scopes under $1000 such as a 7" screen vs a 10" screen for the higher end scopes. I am happy with this scope; it is a big improvement over my old used HP 54600B scope.

[@tautech8196]

Display lag is by design. All measurements are ceased and restarted when setting changes are made. The ever running History in the background also has to be flushed and restarted. Even the cheapest models in this range offer a magnitude more mem depth than in a KS and for a fraction of the cost.

[@veegee24]

@@tautech8196 It's not "by design", it's the result of the software developers not understanding correct software engineering techniques. You have to decouple the UI from long running background processes. It's just poor design. You're right that it's the best value compared to Keysight, but that doesn't excuse poor software engineering practises.
