content: So about $12,000 and the front panel looks like it was designed as a high school project? Weird graphics and a terrible selection of fonts.People might say it doesn't matter, but if you are working a large shop and go for the Rigol vs one of the more established brands, and this thing shows up, it's going to look bad on you for spending money on a Chinese scope that they couldn't even get the front panel right on. That is going to drive down sales to the industrial customers Rigol wants to target.

How hard it is to hire not even a designer, but a normal human from the street to tell them that this looks terrible and cheap?Rigols sort of worth the money on the low end, but if you are paying good money for the instrument, just go for a decent brand.

When I ask for quotes I keep telling that i don't care for bandwidth. Let it be a 10 MHz scope but i still wantAdvanced math, math on math, istograms, uncommon decodes (uncommon for cheap scopes)Not surprisingly the seller will happily throw more bandwidth for free but won't add the real goodies which are why i would choose scope X instead of Y.that is a nice differntiator, it's also part of the reasons i like my picoscopes a lot.If i only want bandwidth i'll go grab an old scope from ebay for one tenth of the price.

content: Quote from: ataradov on August 05, 2018, 03:38:08 amA "normal human from the street" might actually like that kind of looks. I know at least one educated and smart adult person who actually prefers looks meant for kids and teens, to the point that e.g. for entertainment devices he may choose technically inferior products just because of those looks. Though, I think he would not do such choice if it was about "business" or other serious usage, like these scopes are. But a random person from the street might not be smart enough to understand the priority of usability over looks.So, it could still be better to hire a suitable designer, and of such sub-type which is trained for (industrial) usability, instead of "style". At least one major IDE software project went baaaadly downhill because they had gotten a "graphic designer" of the kind who designs marketing web pages and such, instead of one experienced in usability and how it actually works. The results sure looked fancy, but was horrible to use.

content: 3 USB ports, they finally realised the 4 port hub they use to interface the front USB and the touch screen has those 2 spare ports on them essentially free, and then added the 2 sockets. Wonder the power delivery ability, and if they put any sort of overcurrent protection on them as well.Bet the reason they do not see the USB drive Dave plugged in is because it is too large, and they are using an older Linux kernel that does not support over 8G drives natively. Way too common, and really no reason not to have the large drive support enabled in new designs, and not only limited to test equipment either, very common on printers as well.

content: I do not think the design "annoyances" of Far East industrial products are matter of an "lack of professionalism".It is about their "perception of beauty". It is a fully different culture in this regard, when comparing to Western one, indeed.We say their products look like "Christmas Trees" (lot of different lights, colors, rounded shapes, bubbles, fonts, crazy shaped buttons, shiny surfaces, mirrors..). They simply like that..Look at their cars, for example, and compare their design, for example, with a BMW.The same with o'scopes, it seems.PS: see below Western vs. Far East perception of Beauty (imo)

But when you do similar videos going forward, could you improve the audio?I assume this was simply captured via the in-camera microphone. A lot of volume fluctuations as you were moving around, but even when you sat still, the voice sounded thinner than usual. A clip-on mic, or even a stationary one properly directed at the speaker, should work better.

Also, it is easier to clean up a dirty button than a dirty screen, should one not be wearing the gloves and has extra dirty fingers (e.g. working on a piece of electronics that contains lubricants/chemicals/accumulated dirt over years). And, in certain cases good buttons can work faster than a typical touchscreen (i.e. higher rate of actions e.g. when going through a list of selections); no idea if such case would apply or be useful on this Rigol, though.

content: Excellent video, Dave. Thanks!A few years ago Dave reviewed a GW Instek oscilloscope that, just like this one, was functionally sound and capable but people focused on its looks. As I said then: if buttons, fonts and looks are the major criticism, then Rigol should be quite proud with their product. I see a lot of details and button/menu organization that are quite similar to my DS4000, thus it is possible they want to maintain this familiarity intact (and yes, I also find a bit odd on my DS4014 the trigger "Mode" have a specialized button).It seemed a quite capable device with reasonable lag (keysight's are another league, but they carry other limitations by using their old ASIC) but there were not many details on this quick first impressions to make a definitive call on that. Rigol is most probably placing this product to replace both the DS4000 and DS6000 lines.The touch interface seemed quite responsive and reasonably thought (the virtual keypad saves a ton of front fascia realstate, although it is not as nice as a real one) and I see that the buttons surrounding the screen are a great welcome addition if I am not willing to use the screen. Unfortunately Dave forgot to test the touch trigger capability. For a first implementation, that is not bad.I see a fail in acknowledging the USB pendrive. It seems that it is running some sort of Windows judging by the C:\ drive selection, thus I don't know how the pendrive was formatted or if it is a true OS or hardware fail.Basic memory is quite similar to the DS4000, which comes with 140Mpts default, as well as the probe auto-detection and the digital interface connector - a plus in my opinion.The true test would be to use all that with decoders, where the DS4000 fails to do well on the larger time/div settings or delayed trigger. Another excellent test would be specialized triggers (which are limited on the DS4000) and pattern searchability (non-existing on DS4000). However, the flexibility of the LA interface and its digital and analog arrangements seems well put together.Other than that, it is always a matter of price versus performance. A hefty $2.7k for a 100MHz version seems somewhat high (similar to what a DS4014 cost at release time), but with option bundling that may start to make sense when compared to other manufacturers. Obviously that, if the Riglol works, then this becomes unbeatable.

content: Well, to me it looks like a logic extrapolation of RIGOL designs from the past.- its not a mass market entry "toy" like the enormously successful DS1054 series- they want to play with the big boys now- they now have a price range that is not too much below Keysight, Tek or Rohde Equipment (you can get quite some discounts there, RIGOL does not rebate to the same extent)- they try to provide the features their competetitors have, but the do it the first time, and you can see that- ergonomics has never been the top priority of RIGOL. Design as such is probably done by amateurs or not considered important- Uglyness is a matter of taste, unfortunately. They can always claim that as long functionality is OK its irrelevant. On the other hand, its clear that an uglier design does not cost more than a good one, and a good one probably sells more units.- The scope is brand new, and it contains a lot of new functionality. You can expect that bugs are common, and it will take about a year to fix themost prominent ones. RIGOL has deteriorated regarding bug fixing and problem removal, probably due to lack of resources and too much market success.- They copied their pricing policy from other vendors - base unit plus a lot of options packaged in a way so you have to buy several (e.g., look at the protocols), not just one covering most users needs.My advice:- Dont buy it now.- Wait for full reviews.- Read forums for all kinds of problems, updates and fixes.- Always compare prices on what you have to pay including options and vendor rebates.- You max expect that they want to server price-insensitive brand-loyal people first. Only buy if you are desparate or dumb.- Wait at least for the first price correction round (just think of their electronic loads)- Test before you buy !!!- Also test their support during the test period before you buy !!!- If you can, test two instruments from different vendors side by side.-

content: What I see as part of the problem with the front panel design is the line borders around groups of controls. Functionally at least, they need to be simple rectangles, perhaps with rounded corners as per older HP stuff. What we have though is a wiggly squiggle for a line border, and there is no real coherence from one to the other. It is art for art’s sake, not as an aid to function. It might be compared to serifs on lettering that is meant to guide the eye along the line of text from one letter to the next. In this case though the wiggly line just confuses the eye and does not achieve its purpose of grouping a family of controls very well. The mishmash of different shaped buttons doesn’t help either.

content: Quote from: Tom45 on August 05, 2018, 06:36:53 pmThey are probably talking about digits and not bits. As the ADC has 8 bits - it gives us 256 counts or 3 (2.5, if you prefer) digits. So obviously, it is a mistake.Although I don't understand the usefulness of such a "voltmeter". It would've made more sense if they implemented a hardware DC voltmeter with at least 2000 counts so you won't have to use your DMM unless you really need to measure something accurately.I saw the same thing on R&S 2000 series scopes, but it was a bit more useful as they had 10bit ADCs.

content: Quote from: EEVblog on August 06, 2018, 01:50:30 amI can confirm that an onscreen keypad/keyboard via touchscreen is super handy (from my experience with the RTB2k). Saves huge amounts of time for both things like naming saved data files, and (more importantly) allows for direct numerical entry of things like trigger holdoff, probe attenuation, V/div, horizontal and vertical position etc etc. Even if everything else was button/knob driven it's worth having a touchscreen just for that (though it's usefulness goes far beyond that). I find using the touchscreen for menus etc rather than soft buttons (none on the RTB2k) is fine, so personally I'd get rid of them and spend the space on more screen area, though they certainly don't hurt (you're always going to have some duplication of functions on something like a touchscreen scope).

content: Based on my own experience with largest int IT vendors the number of people (the actual "doers") is rather small with product development. My bet the 7000 series has been developed/created by 2-3 guys max. They spent 4-8 years with it. All inclusive - box design, electronics/Asic/pcb, sw, testing, documentation. The other xx thousands employees are usually with production and sales/marketing.

content: Quote from: imo on August 06, 2018, 11:08:56 amMy experience differs: to me this would be true with either an update or a new design but using subsystems of a previous one. In this case, the new ASIC probably demands more people to properly design, test/characterize and document it for the end product design folks. One thing I agree: it is not an army of people but maybe 8~10 for the ASIC and maybe the same amount for the product (including documentation, graphical design and marketing).Regarding the design, the 60 degree angles of the front fascia lines seem to form a brand identity as they match the hexagonal shapes of the vents in the back, the front oscilloscope cover and even some shapes present on the DS1000Z/DS2000 series.

You only get 10 horizontal divisions on the 7000's big, wide screen. However, less expensive Rigol scopes have 12 divisions and Siglent have 14. Does the 7000 give you more resolution per division?

The one you linked is an imitation of the Keysight design.Regarding the MSO7000 series - I'm not sure where it leaves the DS4000 ones, which are similarly priced, but with which you now get less value for money. Maybe they'll get their price adjusted soon?

What I see is a poor imitation of a great design and an original new design that doesn't look half bad and it's in line with their other products.My initial comment was objecting to giving credit to Siglent for that design, when it's not theirs to begin with. They copied the layout from Keysight and those curved lines and angles from Rigol.The same can be said about their signal generators, Keysight layout and Rigol look. If they didn't have the logo, you could easily confuse them with a Rigol tool.

The main reason for the ASIC was most likely to be able to get the 600k wfm/s, everything else was secondary.Edit 2:Now that I think about it, one thing that bothered me about this new scope is its limited bandwidth (only 500 MHz). I was expecting they'd have at least a 1 GHz version (considering the 10 GSa/s), so it's possible the ASIC made things worse and that's all they get with the new frontend.

content: Amount of unwarranted bitterness in comments is quite amusing..Since all are speculating whatever they want to prove their point, i decided to look up some info..It seems Rigol developed 3 custom chips :1. Active differential probe chip (one that goes inside probe). That is high frequency, analog chipActive differential probes in GHz range cannot be discrete design.. This is their attempt to do it right. We will see if they were successful.2. Scope front end chip. That is the chip that represent integrated input channel (analog part) together with attenuators.Similar like above, front end of a scope channel on higher frequencies can benefit from integration.. So far all Chinese scopes were made from off the shelf parts in discrete SMD. This front end supposedly have capabilities to reach 4GHz. If true, using that chip will make 500 MHz scopes trivial.. You slap that on board and route it to A/D. Of course, we'll see how successful they were.3. They developed fast 10GS/sec 8 bit converter with fast buffers at front (to ease driving of A/D) , A/D, and even some DSP on chip (probably some data shaping, filtering, corrections.....details are fuzzy)So far all Chinese scopes used off the shelf A/D. Now they have one of their own. Even if it is not perfect, they can tweak it to perfection eventually. But so far, it looks like it's working well. Remains to be seen.The architecture is completed by SPU (sampling processing unit) and WPU (waveform plotting unit). Those seem to be inside Zync. Or maybe SPU is separate chip. We'll see when Dave opens it.SPU is quite complex , and has 2560 MB local waveform memory with claimed 32GBps bandwith. It also has Real time Fir filters, Hi res mode, Averaging, Sin(x)/x, interpolation, freq counter, triggering, protocol decoders, measure accelerator, and segmented mode capture all hardware accelerated.In WPU and central control unit, FFT and math are running on CPU cores, accelerated by DSP accelerator.By keeping that part of UltraVision II inside FPGA, they can fix bugs, add functionality and upgrade for new generations of products.Their own front end and A/D chips will be probably cheaper that what they pay now, so they could use them on lower end.At one point, when UltraVision II is proven to be functioning well and that they are happy with functionality blocks built in , they might even make an ASIC version of it.As I said before, it remains to see how successful they were in achieving targets.But to belittle huge effort it took to develop all this, it's just bad form.These guys did huge techonological leap compared to what was state of the art for Chinese companies, only year ago.Capabilites wise, it is better than many scopes out there. And if there are bugs, they will sort them out. You cannot upgrade 4 MS memory to 100MS with firmware update....I cant wait to see what new Siglent will bring to the table. That will be interesting too.As for the pricing, market will sort that out. I allready see Tektronix adjusting prices, rest will follow.And yes, if it happens to be hackable, it will be best selling scope in history....

Also 17pF input capacitance in modern 500MHz scope looks bit weird and depending how 50ohm is made it may disturb also it.----But what is nice, they have 2.5GSa/s (4ch on) in 500MHz scope so Rigol do not perhaps anymore fall in wrong made Sin(x)/x trap.Also they have implemented now some kind waveform history buffer so that perhaps also many more users start understand how powerful tool it is, as R&S and Siglent some users may know, specially if Rigol launch it later with some bottom price units.

For about the same money I can buy 10 bit with true 500uV/div and similar memory depths from R&S. Having a minimum sensitivity of 4mV probably means having lots of noise. With the information available it seems Rigol is where Keysight was 15 years ago. The way I see it Rigol really needs to drop the price otherwise this MSO7000 won't sell at all.

content: Quote from: nctnico on August 08, 2018, 05:55:13 pmAs a customer, I didn't run and buy one. I DO expect teething problems. But not because they are "stupid chinese", but because it is something so new it has to have problems. R&S you mentioned came out with a new platform at beginning of the last year. It still has many bugs, albeit they are less and less serious with time. Most stable are Keysight 3000 series, but just because they are 10 years old....And R&S has 10 bit and lower noise, higher sensitivity inputs.. But has it's own shortcomings and much lower update rate. Actually, all the arguments that you mentioned are valid for Keysight x3000T/4000 series. It has same same spec front end.Except basic DS7000 have 25x more acquisition memory.So if you need 10 bit, high sensitivity (power measurements for instance) you are better off with R&S 3000 than with Keysight 3000. Or DS7000.But compared to dsox3000T, hardware capabilities wise, DS7000 makes Megazoom4 look , well, retarded. 4MS memory is just funny. And I know 1 milion wfms/sec is more than 600000 but it is not relevant. But 600000 vs 60000 (R&S) is something you might notice. Or not.DS7000 series is like something between Keysight 3000 and 4000, because of screen in between. Hardware specs are obviously inspired by fast waveform rate of dsox3000 and also by users criticising it for very small memory. They also implemented Tektronix measurement logic, with full buffer measurements (3000T decimates. although quite well), histograms, large 1Mpoint FFT that has better interface (you can set start and stop, or center span frequency). Measurements are architecturally better than dsox3000, and on some measurement it shows. Not to mention severe aliasing that happens on Keysight as soon as you slow down timebase a little.. On certain timebases and setting you will have better results with DS1000Z than with 10 times more expensive Keysight 3000TIt has two channels of AWG (like KS 4000) , which has also one feature I like : while generating signal you can mix in and add separately controlled noise .It has segmented memory (for free not a 1000€ option like R&S), search...It has potential. If there will be problems they will be because it seems to be complex and sophisticated instrument. Those are hard to debug and if there are problems they will be because of that.And pricing is quite funny. Lower freq (100, 200) are good price. With full app bundle you get it for much less than big names. but jump from 200MHz to 350 MHz is allmost 3000€ more... 200 to 500 MHZ is 5000€ more. I would sell for 1000€ per 100MHz, and not sell 100MHz version at all. 200MHz -2000 €, 350 MHz -3500 €, 500 MHz -5000€. MSO for a bit more, let's say 800€. And all options included. That would sell like cakes. Off course, if it works well.But if it doesn't sell, they will adjust prices. Or maybe it will prove to be good enough to make problems for big guys.DS4000 was good basic scope. Fast but only basic features. This one is not like that. It has all the good stuff from Keysight 3000 (fast) and Tektronix 3000 (better measurements) AWG from Keysight 4000, hardware decoding....... If it all works well, it is going to be interesting.And then either premium manufacturers have to actually pump out really better products and keep price ranges, or drop prices.In which case 2nd tier manufacturers have to do same... Good for consumers..We will see who blinks first...And, again, all that will be more interesting if someone unlocks ds7000. Or if Rigol gets smart and just sels fully unlocked scopes in few frequencies and with/without MSO. Or maybe Siglent does that, so Rigol will follow.

A nice number for marketing but anything over 1000waveforms/s will do just fine.QuoteFull memory measurements are OK but not a show stopper because it affects only a few corner cases. What is more important is math on full memory but I don't see any mention on how the math channels are implemented on the DS7000. It that is done on the full memory depth then the DS7000 definitely scores bonus points because that is a more rare but very usefull feature especially when combined with signal filtering.By the way, I'm not sold on the bandwidth/centre/span FFT controls. The FFT still is highly dependant on samplerate and memory depth so having traditional spectrum analyser-esque controls isn't making life easier.Regarding the A-brands reacting: I have to see it first because I've been reading that for years already. So far none of the B-brands have caused any A-brand to change their pricing strategy or change their products.

On paper, in some areas it is class leading.How well it will work remains to be seen.Also Siglent is making their first entry in this market too.Also, how well it will work, we'll have yet to see.If they do prove to be dependable and reasonably bug free, they WILL rattle the segment.

Tequipment usually sells B grade and with the EEVblog discount can be down close to $300, but you get the full factory warente. I don't think the extra $30 or so is worth loosing that 3 years.

There is a forum topic on Keysight E36300 series PSU, and recall. They shipped PSU with several hardware flaws, that shouldn't have passed design phase.

Keysight, while still being good company, is nowhere near old legendary HP in anything.It is a different world, and USA companies nowadays are all run by same company principles. Some of them are better at making you think they care. They are literally teaching Machiavelli in management classes.Milk the brand, as high profits as possible. That means no fundamental research, no product development unless absolutely necessary. Reuse and recycle as many old parts as you can and make only cosmetic changes. If you develop something new make it cheap , make it look fancy, and pay more for front panel design than for base board. Looks and fame sells.And as long people buy that crap, they will do it like that.In meantime, Chinese are pumping out products that work better by the day. With 50% profit margin, not 5000%. Which means people can afford it.In private (hobby) environment they already rule. In small company segment also, in last few years.I next few years they will rule 3000 class too If A brands don't take the seriously. Which is the bread and butter of scope manufacturers.Tektronix, and Keysight and LeCroy will rule 20, 40, 110 GHz scope market. Chinese don't have that. Yet.

I wouldn't call a salesperson from a distributor a credible source. When I visit companies I see A-brands on the desks of electronics developers only. Other then that there is the occasional low end Rigol and (re) brands from Element14/Farnell and RS but these are mostly for occasional use.

content: Well said 2N3055. I think you have hit the nail on the head.Sure there will be some bugs but seems they have decent bug reporting and regular firmware updates and that is really what people want. There isn't a scope released by any of he A class companies that does not end up with some bugs.There is definitely a difference between how the same actions by a high end manufacturer and a lower end are received. I hope the new Rigol scope works out well for them and they continue to improve their design processes.

content: Quote from: 2N3055 on August 09, 2018, 07:03:49 amIt was one day long time ago I tell to some noname chinese manufacturer that please, best and most easy way what you can do for understanding T&M designing (exept modern hardware things naturally, but it is not so important because developing is much much more that just circuit design - first need have some idea) but thinking before muscle work is important if want rise to B+ or A class. If only want fast win and fill pocket... yes it can do but road is short.Read carefully all or most HP journals over the decades and think what all things are important in development and final product also without forget documentation. Quality thinking, design team "spirit" and "flow" and how important is that there is also working very experieced and skilled peoples who really understand how to use equipments (for UI design and also mechanical design... try example stack today these tabletop plastic boxes what mostly looks like childrens toys and designed as womens clothes and shoes thinking some fashion. Of course one reason is that many things are designed just for buy, use bit and throw away and buy again next model... every second year and better if life cycle is more short. More pixels and this and that as some time ago with digital camera boom. But, still IN have never seen better photographs what was some take around 1930. Same with scopes etc. Skills, knowledge and experience is much more and more overlooked and only peoples think what this instrument can do. Without any worry about what are user itself specifications.As we can many times seen also here peoples buy nice instruments but after then are like withjout any idea what it is or how to use it... windering what not connected probe show on the screen and if it is manufacturer made bug or some other error in design... and many other things. And this we can many times see when more experienced some users do even when we can assume he know what he is doing. Of course noobs are easy to fool...Of cvourse we need better equipments but.... who cares better users? Who can develop users?BTW, old HP did even this!! (also old original Tek some) Lot of courses, lot of teaching materials, lot of shared knowledge and so on.Who is FIRST chinese company who do it... what year... perhaps 2020, 30, -40 or do it happen never.

content: Quote from: rf-loop on August 09, 2018, 09:27:39 amRF, I agree with you that old HP and TEK did that. I learned how to use scope as child, on a Tek 2205 from user manual. And also there was additional Tek book (sort of similar to todays ABC of scope primer). I learned all from there.Also many things I learned from excellent documentation from HP, IBM etc etc..My point is, THEY don't do it anymore. Whatever resources they have, are old, still from before, from that time. Reprinting old whitepapers with a new logo and design is not new value.R&S is actually doing some effort here, but not much.My point is that A brands are not doing it anymore, or doing on much smaller scale that they get credit for, undeserved.That is why Chinese brands don't do it. Old documents are publicly available. Buy any scope, just download old Tek book. Buy and DMM, get old HP measurement books.. And even A brands are not creating new materials, new value.And A brand support is not what it used to be. No individual spare parts, no schematics, they will tell you to send it in for repairs, same way the Rigol or Siglent do.What is added value of support? A-brands have better bug reporting procedure? For the money they charge, they should have much less bugs that B brands to begin with. At least that is their explanation of much higher price.Remember "Scrap the Toys, Get a Real Oscilloscope" patronizing bullshit ? That is their opinion of customers.Also there are cultural differences form old days. I know it from my country. In Eastern block, you had to make do with what you had available. Nobody cared if instrument was hard to use. If it was capable of achieving results, it was your responsibility to make effort and learn how to use it. It wasn't seen as a hard to use instrument but as your excuse not to work hard.And if there was something you didn't understand, you had to figure it out by yourself. There was no Internet, nobody to call, maybe a colleague, maybe he knew... You had service manuals, you repaired it in house ("what do you mean pay somebody else to repair it. Aren't YOU the f**king EE? I pay you already. You have schematic, fix it. Tell me what parts to order... Off you go.."")In China, they don't expect they need to tell you how to do you job, or hold your hand while measuring rise-time of signal.If you are not qualified, step aside, there are others that know how to do it..So manuals are basically exhaustive list of what functions are present.I do agree with you that if they would realize this, and started doing more in this regard, that that would make them more popular.But one of the reasons their prices are low is that they spend less money on marketing activities (which this is).

content: Sinisa, well said. I was also raised in a country without resources (at university in the 1990s we had to get by with HP200CD oscillators, for example) and way before the internet (magazines and books were our primary source, and language barrier was high).One remark is that, from my experience in the industry, companies nowadays are releasing much more troublesome products ("customers as beta testers") not because of pure evil, but also because the profit margins cannot absorb the longer development and test cycles these products require (the design teams are smaller and the resources are much more scrutinized when compared to an era of plenty such as the cold war). Despite the fact that software is conducive to an attitude of laziness or procrastination (everything can be fixed at a later time), its complexity increases at a geometric rate from version to version (as Nico mentioned a few posts ago).A similar scenario happens with the production of technical content: the tasks of creating training content, technical literature and user's manuals is frequently assigned to a smaller group of people that also have other tasks such as applications and support (I am immersed in that daily). The consequence is there's a tendency to cater to the more pressing issues (or low hanging fruits) and release short Youtube videos or very focused written application notes, while the deep technical content tends to become an over arching project that takes a lot longer to reach a usable status - if ever. User's manuals still demand a great deal of maintenance (new features and bug fixes added quite frequently) and this is even worse with pure software products, where people do not even take the time anymore to read the manual and go directly to Google, Youtube or other resources.Quote from: 2N3055 on August 08, 2018, 10:12:42 pmI have to disagree with you there; the latest firmware releases of the DS4000 do a decent job in decoding and are different than DS1000Z series in the fact they decode from memory and not the screen (one of Nico's pet peeves).The absence of a search capability is my biggest annoyance with it, and I can live with its annoyance of having trouble decoding above 50ms/div, but YMMV.Also, depending on your use, the small memory of the DSOX3000 completely blocks you from even considering a purchase.

I apologize for confusion I created I was exaggerating a bit to prove the point. For me, for my use, lack of search made it not much more useful than DS1000Z. That is why I sad that, rather clumsily... Sorry for that, I hope i explained it better now.Regards,Sinisa

content: Quote from: 2N3055 on August 09, 2018, 10:46:37 amIMHO this is a bit of a rant. The A-brands demonstratingly have less bugs than the B brands when an instrument is introduced and are more committed to fixing bugs in a reasonable timeframe. Also in my experience the A-brands work better in corner cases. This is one of the reasons I've turned away from buying cheap test equipment. The chance that it won't perform at some point is high and then I need to spend money again to buy 'the good stuff' (besides time/money wasted on messing around).

If you want something that works from day one- buy an A brand if you can, or a very trusty mass model from a B brand- get a model that has been on the market for years and that does the job you need- avoid new and fancy stuff if you can- read the net for reviews and bug reports.- negotiate hard. Your chances with old equipment is much better than with new models.much luck !

Your personal experience is based on sample of 1. You bought one Siglent scope model as an early adopter. Which is bad idea anyway, being early adopter.Quite frankly I think you have every right to be pissed at them then. I would be too if I had a story like you. Because of YOUR story I am a bit wary of Siglent. I've seen some mistreatment of compensation capacitors issue etc. I do have a reservation about them a bit too.But because of what happened to youonce, youshouldn't extrapolatethat:1.AllChinese equipment fromallmanufacturers is shit.2.AllChinese manufacturers are shit.3. All manufacturers and productsnever change. They never learn anything and can never get better.4. Also good ones cannot change to worse. They are just blessed with goodness..... (hint: Tektronix)When Keysight sells you very expensive (for what is is) power supply that has basic flaws at being power supply (it has switch on transients that damaged 2000 USD development boards, and cannot measure correctly ..) and has fundamental flaws in it's core analog circuitry, then you are not pissed at "crappy Americans". Than, after waiting for months for them to admit it, they finally replace it for you and then you are happy with their excellent support. What about handheld meters fiasco, recalls of 3446x series, flash rot on 2000/3000 series, exploding PSU's on 3000 series.... Etc Etc..No, they don't exist. You have excellent support. It's a premium manufacturer, these things don't happen...I'm a realist. Anybody that expect that something as complicated as MSO/DSOX3000 or MSO/DO7000, or R&S2000/3000/4000 series can be developed in a year with zero bugs is, well, delusional.And I mean by anybody, not even the mighty ones..Keysight 3000/4000 series is the most stable of all because it has been debugged for 10 years. If you can, assemble list of all erratas and bugfixes over the years. I took a quick look, for 2000/3000A it is a 23 pages document, including enhancements and bugfixes. For 3000T it is additional 11 pages. But after all that, it is rock solid.Because of being that old, it is also horribly overpriced for what it is. I would rather go with LeCroy 3000 or R&S 3000 series. I like R&S 3000 best, but that thing is as buggy at the moment as you think Rigols and Siglents are. Which are not anymore. LeCroy has it's funny little annoyances too.I apologize to everyone for writing so much.And Nico, I do understand your frustration. I respect you have your opinions. But, please, you have to stop telling us what we should do or think. We heard you first 100 times. There are many people here that have quite positive experience with Chinese equipment, quite opposite from you, provided that you don't have unrealistic expectations and accept those are not high end products.I wish you all the best, and thank you for all the stuff I learn from you. If you wish to reply, please do, but I would like to stop arguing with you. I respect you and don't want that. I wish we could stop here and agree to disagree if we cannot agree to anything else.Regards,Sinisa

content: Sorry to say, but there is a grain of truth in all this rant. The story runs like this:- A low-end model is simple. Simplicity in software means less errors.- A low end model sells in millions or at least 100ds of thousands. The chancethat a user finds an error is quite high, just because of the number of peopletrying everything out.- Lots of complaints demand a fast problem fixing cylcle. A manufacturer ofa mass model cannot afford a lot of bad press so the fixing is done with a high priority- After a a reasonable timespan (1-2 years) the low-end model errors areetched out and you have a reasonable product.Not so for the high end.- Higher complexity is more prone to errors, on a nonlinear scale- A small customer base results in low sales volume- Mostly specialized applications, not generalities like the low-end models- Bugs are detected, but by few users only- These bugs have low priority due their small numbers and low public attention- It may take years to remove them, if ever.This is the primary dilemma of a rising star company which had a lot of success on the low end. If they move to the pro segment, user expectations are very different from what they are used to. Pros are absolutely intolerant to missing specifications, bugs or lousy or nonexistent product update cycles. Arguing that you are cheaper than A brand XYZ wont help you there. I have seen this a lot with Rigol stuff. Their cheap line is OK, but beware of some pro instruments.

Even Dave's camera was having trouble and focusing on the foreground reflected by the screen.The excessively complex control panel markings add nothing and detract from intelligibility. Were the designers simply courageous or did they get paid for every line, angle, color added? I like the simple lines and shaded areas used on old Tektronix font panels.The FFT function discards phase information. I am still looking or a modern DSO which supports this.No peak-to-peak triggering.No trigger after delayed sweep.Supports windowed measurements.No high resolution acquisition mode? Does that mean that again measurements are made on the display record?1mV/div sure looks like x5 or x10 digital magnification but the specifications unambiguously say 1mV/div sensitivity.Marketing materials advertise shortened overload recovery time but no specification is given. Cleverly, this is done as an image so a text search does not find it but it sure caught my eye.I could see the interface lag when Dave was operating it. How slow does it need to be?Did Rigol confuse differential with two channels? Does each module have two differential channels? The photographs do not show that.

Some of the specs do look quite tempting I must admit, but that UI and all the bugs it entails is something you gotta live with. At the entry level you have no choice, but there is much better choice in this price bracket.I personally wouldn't take a chance on Rigol if I had $3-4K+ to spend on a scope. That R&S RTM 3000 looks mighty fine however.

content: Quote from: nctnico on August 10, 2018, 08:02:20 amIf it works, DS7000 has many things those mentioned don't..But it remains to be seen if it some advanced prototype or fully featured product.I have so far compiled few objections:1. No high res mode. It can do averages from multiple triggers, but not high-res running average mode. Big fail.2. Still there is visible lag from button changes to starting redraw with new settings. Frankly, it's not a problem, but it simply shouldn't be there. Optimization of that is in order.3. It is not low noise front end. It is in DSOX3000/4000 class though, but worse than R&S.. Or Lecroy WS3000 which is also 8 Bit.4. No math on math. That's no good. For instance: apply filter, that pipe that to differentiation. Otherwise you just get too much noise. Especially when you don't have low noise input, and you didn't implement Hires. Fail.5. Thinking about that, filters should be separate from math. I should be part of channel setup, together with normal hardware bandwith limiting.6. There is no custom math formulas. Math is worse than (except FFT) than in DS4000. In fact , it is pretty much same as on DS1000Z. Fail.I'm sure if I had chance to try it I would find more...Thing is, hardware is capable of being so much more. We will see if Rigol is capable to bring it to it's full potential.And of course, how long will it take if they do.

content: Quote from: 2N3055 on August 10, 2018, 07:16:46 amPeak-to-peak automatic triggering continuously sets the trigger level to a percentage of the peak-to-peak signal level; it is similar to triggering with AC coupling but it ignores duty cycle. It is great for fast hands free operation when you are probing around in a circuit. Automatic level triggering sets the trigger level after the trigger times out which is much slower and annoying if the level drifts to a point where it barely triggers preventing timeout.I do not know of any modern oscilloscopes which have this feature but that does not stop me from noting its absence.QuoteTrigger after delayed sweep removes jitter. It was more important in video applications but it still has its uses like if I want to view reverse recovery of a diode in a switching regulator where the duty cycle is not stable and I cannot trigger on the reverse recovery itself.QuoteWindowed means the measurement area is set by cursors which I found in the manual. I do not like to use the term gated for this because that more properly means that the measurement window is controlled by some other signal as with a gated frequency counter.Quote from: 2N3055 on August 10, 2018, 10:06:38 amIf they say low noise then they should specify the noise level. The automatic RMS measurement function should be able to measure the noise level directly but on some DSOs, RMS measurements only work on high level noise free signals.Like "fast overload recovery" and "unlimited internet", everybody has a "low noise front end" when they do not have to specify it.QuoteSomething else I always look for is being able to average the output of the FFT and not the input which is handy for making noise measurements. I would also like to have an FFT normalized to SqrtHz when this is done. Computers are good at this sort of thing yet I usually end up doing the normalization manually.

If there are major problems now, I think it's only fair if Dave informs Rigol and requests a feedback (or maybe he was promised a rush job of bug fixing of the firmware and he is waiting for this).Anyway: I am sure, creating a large review with comparisons to other scopes will take days. If the video has 60 minutes, I am sure shooting and editing will take much much longer.

content: Quote from: imo on August 17, 2018, 07:25:01 amWell, we disagree here. In my opinion it is a sign of good journalism to give others the opportunity to express themselves on reproaches. If Dave should have found bigger bugs (which he did not mention anywhere and which is pure speculation!), then it is absolutely legitimate to give Rigol the possibility to provide an answer, most of all as this is a brand new product which can never be bug free. And should Rigol say: "Please wait another week with the review, because we are developing and testing a new and much much better firmware", then it is in the interest of all future potential buyers to postpone the review for this long. That doesn't mean he shouldn't mention the problems! But it would be much more helpful and professional to add an "already fixed" to this.Postponing/waiting has nothing to do with 'not being independent'. EEVblog is not "Fox News" or "The Sun". And Dave certainly won't wait forever. But if it's just a few days, it's good for all of us (win-win) as you get a review of a device including the latest firmware.What you are asking for is a bashing now ('hurry before they come up with bug fixes') with showing bugs that would be fixed long before the device is delivered to you. But in the end would only be good for entertaining some, not for providing hints if to buy the product or not. That doesn't help anyone - so it would be a loose-lose situation (well OK: a win for the entertaining).

content: I agree. If you review something, you do it on what the product does or does not at the time of the review.You may mention comments on future updates by the manufacturer, but a review is a snapshot of facts and not the intentions or plans.I remember Daves review of the first DP832s; The review was put online, RIGOL reworked their mainboard fixing some problems (even replacing the mainboards of existing customers free of charge) and Dave did a follow-up review where he stated that its OK now.If you want to be perceived as unbiased you should avoid all notions of "embedded" journalism where the manufacturer is given some control of what you say and what not.The borderline between marketing and journalism must be very clear.PS: In Germany car journalists are only given new cars for testing if their reviews in the past have been pleasent. All other ones have to wait until the car is on the market.

There was a lot of space around, so they did this with no explicable reason.They fixed this in newer versions (I have 4 DP832As, but only the newer type), and they said that owners of the old version could send in theirs for a new free mainboard.The behaviour of RIGOL at the time was a reason why I bought quite some RIGOL stuff. To me, these people appeared as honest and dependable. Eveyony can make errors, but they stood up for it and fixed it. It was a trustbuilding measure.For more info, why dont you have a look on Daves first and second review of the DP832 here on EEVBlog ?PS: I have heard of the overshoot problem, but I need to measure this one with the versions I have.

While making my own reviews I report bugs / shortcomings to the manufacturer and in some cases they provide a fix for some of the problems found during the review period. But I'm not going to wait forever because when people buy the instrument shortly after the review they'll also receive what I've reviewed at that moment. If a piece equipment isn't really ready for release then it is bad luck for the manufacturer but the review goes online.

In theory, there's no discussion about hacking scopes used 'commercially', in reality, there's however some sort of twilight zone here...And honestly, when one sees how BW upgrades are typically priced, this is really calling for hacked machines !If've heard companies arguing that corporates typically get significant rebates on those... so at the end, those who would be able to pay for the options get 60 or 70% rebate, and those who can't afford them (at list price), don't get any rebate... while this might commercially make sense, it actually creates the conditions for some to consider hacking their scopes...

Forget about that.If they are asked for substantial rebates, they need a justification, there is paperwork for them, ... They are only human and a bit lazy, too.This is how I did it:I told them that I will not only try theirs, but also units from their competitors. I gave model numbers, I told them where they were better andthey were worse, I published my tests on the net. So, they had the best (and probably the only effective) reason for substantial rebates: *competition*.That worked.Example for some tests:https://electronicprojectsforfun.wordpress.com/test-equipment/test-equipment-measurements/a-high-speed-oscilloscope-comparison/https://electronicprojectsforfun.wordpress.com/test-equipment/test-equipment-measurements/rf-signal-generator-am-modulation-quality/https://electronicprojectsforfun.wordpress.com/test-equipment/test-equipment-measurements/rf-signal-generator-iq-modulation-quality/

content: Quote from: nctnico on September 04, 2018, 05:24:45 pmI can't necessarily understand the rep's attitude in this case; to me it smells like he did not believe at all in the customer's expertise and tried to pull a realtor's attitude: show something wonderfully irresistible only to try to take advantage of the awe of the customer (quite childish IMHO). Perhaps that is what Sinisa's rant talks about. Regarding the oscilloscope itself, JPortici's review is what I remember as well.Quote from: 2N3055 on September 04, 2018, 05:49:25 pmI don't know about Croatia's market, but here in test gear haven this money buys you quite a decent used oscilloscope.

content: The inbuilt sig gen looks identical to the one on the Rigol DS1074Z. Max 25MHz sine & 15MHZ square waves.You'd have thought that for a 500MHz scope costing in excess of £10,000 when fully upgraded Rigol would have taken the opportunity to improve the sig gen too, say to 100MHz sine wave; or is that too much like common sense?

Keysight MSOX-3104T - up to 20 MHz, R&S RTM3000 - up to 25 MHz, LecCroy Wavesurfer 3000 up to 25 MHz...Only Tek MDO 3000/4000 go to 50Mhz... None of them go to 100MHz.Siggen on a scope is not a full instrument, it's more like a supplementary function, to give a handy basic signal source that is right there. Actually, 2 ch on Rigol is more useful than higher than 25 MHz frequencies..

Extend timebase to say 500ms (default test max 5ms), and much sharper edge (~2ns) or Arduino version of test. They claim full memory (guess 500Mpts? then) measurements, and in real time. Something thought to be impossible and even unneeded by some not long ago...

content: Those caps are in the power supply, which was outsourced. Rigol probably treated it as a module and didn’t spec the components used inside. It will be interesting to see how many will fail during the three year warranty period.

content: Looking forward to a full review, but lots of unanswered questions still:- Still software serial decode?- Same super crappy encoders like the 4000 series?- Laggy UI?- Web interface?And most importantly, will it suffer for years with very poor dedication on the firmware side? Anyone that bought a 4000 or 6000 will be hesitant to purchase this.

content: Quote from: Fungus on September 21, 2018, 05:08:52 amDon’t get me wrong. I didn’t mean the failure comment to be critical. My Rigol DS4000 scope has a CapXon populated switching supply in it, and it has been working fine for six years.Also, despite the firmware hassles on the 4000, I am still considering the 7000 series for a possible upgrade. I, like others, anxiously await a thorough review.

content: Quote from: commongrounder on September 21, 2018, 04:57:09 pmSimilar scenario here, but mine is 2015. I suspect Rigol is (rightly so) giving business to their fellow countrymen and Capxon seems to have improved their product.Quote from: PA0PBZ on September 21, 2018, 06:35:03 pmNot only that, but a golden rule of electrical power transmission: the higher the voltage, the smaller the losses. The board already heats up as is, imagine carrying higher currents in longer traces.One interesting detail I found funny about the teardown was Dave's comment about the HW revision in resistors - I found the same in my DS4014.https://youtu.be/zbU2our0qCI?t=12m43s

content: Quote from: Fungus on September 21, 2018, 10:23:53 pmNo because 'consumer' components will always be cheaper. IMHO it is a mistake to think that very expensive to produce ASICs can somehow be used cost effectively in a low cost oscilloscope. Just look at the number of memory chips around the ASICs. A Xilinx Zync based scope just needs a multi-channel ADC and one memory chip to function. You can't beat that with an ASIC.
