content: I noted SDS2000 series are discontinued. The SDS824 appears to be cheaper the spec seems somewhat better, anyone has 'hands on' experience with this series of scopes, is this a new model?Dave

content: SDS2000X Plus and SDS2000X HD are both still active scopes. SDS800X HD series is a nice entry level / budget scope series. All of them have dedicated threads here with plenty of discussion, including a detailed demonstration thread for the 800 series.

content: According to Telonic (Siglent dealers) the SDS2202 and SDS2352 are disconitinued, I never took note of the screen size.... readibg the forum glitches on the SDS800's kinda put me off. Will have to have a rethink here, it was the 200/350Mhz I was looking at.Thanks all, Dave

content: There are some who want to look like fans of the 800 series, but who delight in finding and exaggerating every quirk or bug. It's really a disservice to the scope series as in everyday use they're powerful and a joy to use. The 800 series are an incredible bargain, but if you need more features, you may have to spend more money. Few people actually need more features.

content: Quote from: Davy on February 13, 2025, 03:11:02 pmThose are the higher BW SDS2000X Plus 2 ch models.SDS2102X Plus is still available.My tests on these 100 MHz models revealed a -3dB BW of ~185 MHz.QuoteSad that, most complaints are pitiful stuff when the DSO is perfectly functional and as Conrad says amazingly capable for a low cost instrument.Still, it's only a 7" display which can be a problem for some and the 10" models become more attractive.QuoteSDS824X HD provides ~240 MHz -3dB BW IIRC.Most everything you need to see about SDS800X HD is here:https://www.eevblog.com/forum/testgear/sds800x-hd-review-demonstration-thread/

content: Quote from: 2N3055 on February 13, 2025, 07:18:22 pmOr maybe some specific member here has managed to lower so much the S/N ratio that at a cursory glance this little jewel of a scope seems riddled with all kinds of issues.Perfect? No perfect tool exists.This might not be the best fit for your needs, but it's extremely capable and has no showstopper or even semi-serious bugs.And I say this without even taking the price into account.To Davy: I hope you evaluate what you read taking into account the reliability of the information source.Look at the thread that tautech linked, if you haven't yet, it's absolutely worth it.

content: Quote from: newbrain on February 13, 2025, 11:12:24 pmOh you mean a person that has 150 posts of 500 in topic about bugs, where there are maybe 50 posts about the bugs, of which there was maybe dozen of real bugs found, most of which were fixed long ago.. the rest of the posts is people begging this person to stop trolling us all...This is exactly why I was so violently opposed to what that person does. When you write literally 1000 false posts how something is bad at one point people start believing "something must be wrong otherwise there would not be so much complaining".Even if it just one person that might have some problems or hidden agenda doing it..

content: Quote from: eTobey on February 15, 2025, 06:17:28 amYes, people should. Except that in a topic that was reserved for real bugs you made 143 posts out of 450. Most of then off topic, repetition of already said things or your demands that manufacturer changes the scope because you (who is by the way beginner in using scopes and didn't know much when bought one) know better than whole industry and thousands of people that have been using scopes for decades.Then there are numerous attempts to explain you how you should behave in a forum and how things you are saying are wrong or should not be discussed here. On which you mostly retort with more noise.If we take into account your unrelated posts and not OT responses there, maybe 50 out ot 450 are actually about the bugs...Here is the topic:https://www.eevblog.com/forum/testgear/sds800x-hd-bug-reports-firmware/msg5455364/#msg5455364Pay attention to failed wish by the OP"This thread was created mainly for the following purposes:- Avoiding a wrong perception of "too many bugs".- makes sure that the real bugs get proper attention and are not lost in the noise."Which you so successfully sabotaged one starts to wonder what are the motives for such behaviour.Yes, if they have time to sift through, people should, and see for themselves.Factcheck:This scope was released around a year ago. In meantime it had 3 FW releases that fixed almost all known bugs. There are few minor ones that are going to be fixed in incoming update.Releases are publicly available and free to download to anybody, including release notes.Scope was released feature complete, meaning all features and functions promised in a datasheet were available at release.OTOH lately Keysight and R&S released multiple scopes that cost 20-50x more money. Literally.R&S scopes were feature incomplete (you had Zone button that didn't do anything). Zone triggering was added only a year later although it was marketed and sold with that function featured. THey had one FW update in that period. And yes they had bugs. R&S also started to limit access to releases only to customers they find "appropriate".Keysight also released HD3 series without some basic stuff (like X-Y mode). To their credit, they released 3 FW updates in 3 months and at least made scope comply with datasheet. But in 3 months and 3 releases (4 if you count initial) there is already 7 pages of bugfixes). 7 Pages. Compare that to less that one page of found a fixed bugs in SDS800xHD. Keysight, at this time does not limit access to documents and FW updates.So yes people shouldn't believe me. They should not believe to you either.They should do fact check.But you are successfully sabotaging any fact checking by drowning us in endless noise.At his point I also ask people to consider why are you doing this? Cui bono?

content: Quote from: newbrain on February 15, 2025, 12:56:42 pmMight as well be. But after so much time I don't really care anymore if person has problems or does it deliberately for some nefarious reason. It causes disruption and refusal to stop after being repeatedly warned makes it deliberate disruption.

content: Quote from: Davy on February 13, 2025, 03:11:02 pmIt depends on what you read.But this is a prime example of the dark side of a forum in general, in which case it is exactly the other way around.The 800X HD series is currently the “best” and most complete scope you can get for theprice range.This has been “proven” multiple times, see the link in my signature.There are a few people who think that a cheap scope has to be able to do everything they need. The performance of such a scope has to be on par with a €10,000 model in every way, otherwise the scope is rubbish.This has something to do with the knowledge background of these people, which is then reflected in their expectations. Unfortunately, however, more attention is paid to their complaints than to the majority of satisfied owners.
