content: Okay, there are a lot of reviews (on this site, as well as others) of scopes between $300 and $600 US. The ones that jump out are the classic Rigol DS1102E (and it's little brother), the Hantek DSO5102B (and it's siblings), and the Owon SDS7102. Then, of course, there are the other ones that are the same scope, just a different brand name. But it seems, being in the states, that these are the big 3 in the ~$600 or less arena.From what I can gather, the Rigol is pretty solid, but at this point, a bit dated (small screen, no real standout features, etc). The Hantek is extremely hackable (as per the 100 page thread on it here). And the Owon is similar to the Hantek with a few more bells and whistles, but is also missing some things (which I guess the company is adding now with newer firmwares). Also, I note that all these units are from at least 2011 and older. Coming from computers, 2 year old models are pretty old. How often are scope models updated?I don't really have a list of things the scope MUST do, since it's my first, and I'm really teaching myself this stuff. I'm a Systems Admin by profession (which is one thing that really draws me to the Hantek), but I've always dabbled, poorly, in electronics and would like to get into it more. Having a usable and inexpensive scope seems like it would be a good tool and would probably be all I would need for years.Anyone have any thoughts? And before it comes up, I really can't justify the Rigol 2000 series (DS2072) unless there is something REALLY compelling (for a beginner) about it that these others don't have. The price point is twice what I was otherwise looking at. =(Thanks for your time.

content: I'm in the same unfortunate position as you are; except I have actually just played with a Rigol. You are right, it's pretty solid but I *have* to warn you against the horrible noise the DS1000/1100 serie produces... also, the screen is pretty small.In spite of it's mixed reviews, the Owon SDS serie is my current favorite candidate, due to it being quiet, having a large screen and 10M sample memory (good for capturing serial data). I am not in a hurry though, will monitor these threads for a few weeks before committing. In the perfect world, tomorow Rigol would introduce a revamped DS1000/1100 serie with bigger screens and more sample memory, which would make the choice much simpler.

content: Update to my previous comment about the screen size: Mark's (marmad's) review of the Owon device includes screenshots which quite clearly demonstrates the difference between a larger screen + resolution (yes I know the waveform resolution is the same 8 bit).

content: Yeah, I have a month or more to make the jump.Looking at the 2000 series Rigol, it seems like it pretty much brings the Rigol up to par (if not beyond) the Owon and Hantek. But again, it's nearly twice the price of those units. Maybe their name has earned them that cachet.The Owon does seem very capable... I just keep looking back at the 100+ page thread about the Hantek and how hackable it is. Do we know if you can hack to get better bandwidth? Sounds like a big advantage is there's a single ADC which I guess produces less noise?But all that just makes me think, the Owon is the newest of these three... so it's grown off the previous two. I also kind of dig the fact it can run off battery (though I don't see myself using that a lot (but then, maybe I would)).Good to know about the Rigol. While I'm thinking about moving my bench to the garage, until that time, a loud fan would be kind of annoying. Wonder if the Rigol 2k has that issue.Any thoughts people have would be awesome.

content: Don't get caught up in the trap of buying anything above what you know you need.Are you buying a scope because hacking it is interesting? If not, then don't consider that as a differentiator. Does the higher screen resolution really matter for you? If not, then that feature isn't mandatory either. What do you intend to do with this scope? Do you even need anything more than 50MHz bandwidth at this point? Etc.At that point then you can really compare apples to apples. Keep in mind that if you are a beginner then you *probably* don't really know what your needs will be a year or two from now (heck - you might not even really know what they are today). So don't assume you need to blow money on features you might not ever care about. From what I can tell, most folks outgrow their "starter scope" after a couple of years, and by then they really know what they want/need. And well-kept scopes seem to hold their value reasonably well (though you may end up just keeping two or more around).I recently picked up a Rigol 1052E because it was the cheapest starter digital unit with the features I care about for now, in a device small enough to fit on my current (cramped) workbench. Maybe in a couple of years I will feel a need for higher bandwidth, more channels, more features, or even just a bigger screen. By then the technology will have advanced and I will be able to get more value for my money. And maybe I won't need anything better than this - in which case I saved a ton of money by not buying features I don't need.If you end up getting a Rigol, don't forget to do the quiz in the checkout process to get an extra $30 off the price.

content: I purchased the Rigol DS1102E a couple weeks ago. The fan is pretty quiet. They might have fixed the noise problem.The waveform display is not that great but I bought it more as a waveform analyzer since I have a couple of Tek analog scopes for viewing distortion and signal tracing.The frequency function is accurate within .002%of my good counters and the measurements display works well which is what I purchased it for. I can't justify spending a thousand+ dollars on a digital scope when this 100 MHz scope gives me the info I want and a good vintage analog Tek scope still has a better display for under $150.

However, Mark Madel's mentioned the Rigol's fan noise @8:40 into his Owon review:Owon review...as does this guy here at @6:32:another reviewerI also just shot a small video with my phone to demonstrate what I mean:This kind of noise is completely unacceptable to me and is pretty much the single largest reason for why I disqualified the Rigol. I'd love to hear it's fixed in latest generation, but it's definitely not a great marketing aspect of the scope.

Either I got lucky or Rigol fixed the problem.I have no noise at all compared to that last video. The lights and screen are really the only way to know mine is on.

content: Just for reference, I have purchased a DS1102E for almost a year now and mine does the fan sound shown at the two videos below. Therefore Rigol probably heard the complaints on the web and replaced the fan.For me personally it is not loud enough to justify replacing it.When I was trying to decide on the oscilloscope, I looked at the offerings from Owon and Siglent, but since I tend to keep equipment for long periods of time (I still have a 15+ year old Kenwood CS4025 bought brand new), I chose Rigol because of their excellent reviews on the web regarding build quality.

content: A test instrument should measure reliably and perform exactly as the spec sheet says, so you know its has no unknowns and is fully predictable when you are probing unknown circuits. i spend my time on my circuits not troubleshooting or hacking my scope's reliability, unless that's what I want to do.The 1052e has been around since 2007? and while not the latest and greatest, its also been tested for a longer period, to know its a reliable DSOdesign, with the occasional assembly defect that is usually found early in the scope's life and is easily fixable under warranty.As a started scope, the 1052e will help you appreciate what a better DSO will do if and when you are ready for it as MacAttak says, particularly in the USA with Rigol USA here to honor the 3 year warranty.Outside the USA buyers are left with the sellers warranty, as many countries do not have a local Rigol head office. Also the price differences may not be so marked, so competitors are more attractive as if a glitch occurs, and its past warranty, you are left shipping it back to China, which is probably a futile effort. So local hackers are your source for service, and if they know Owon or Hantek more, it may be better off to use those scopes rather than Rigol.

The fact the Hantek runs these is interesting to me. =) And really, I don't KNOW if I need more than 50mhz, but it seems that even the Rigol 1052 can be "hacked" into a 1102. Is there a good reference for what I would need those extra 50mhz for?Quote from: MacAttak on April 03, 2013, 12:14:46 amYes, again, totally makes sense. I'm a bit confused on the quiz thing though.

Part of me just loathes the idea of buying something from A. 2007, and B. With a 320x240 screen. =/ On the other hand, looking at their site, I see there's a rackmount option, which is something I can't see the Owon doing (it's just a bad form factor for this), and I don't know about the Hantek.Anyone still have their Rigol from 2007 in service? I mean, is there any reason one of these DSOs wouldn't last 10+ years?Thanks!

content: The "quiz" is in the order checkout process at the Rigol NA site. In the shopping cart there is a button that says "Earn an extra discount" right above the total. I am not sure how long they are doing this, but the button is still there. Even without the discount, the pricing directly from the manufacturer is competitive with resellers (or better). Their shipping rates are also competitive, and very fast.The quiz is really just a gimmick to get you to look at the spec sheets of their more expensive models. Things like "which of these advanced features are supported by the 4000 series models?". And you would just go look at the product page for the answer. If you miss a question then just start it over. Worth the few minutes to save $30 though.

I was mostly using it in my noisy shop, and it was drowned out by the drone of some server fans which are near my bench.Several months ago, I brought the scope up to my home office to use it while I was writing some firmware. I found the fan noise to be OK for the first few minutes, but it got awful after that. I ended up replacing the fan with a Noctua 60mmx25mm fan and used one of the speed-reducer adapters that came with it. It's not silent, but it seems to be a good compromise between noise and airflow. I tried it on the slowest speed, but it cut the air flow down too much for my comfort level.

The only thing wrong with these has been the rotary encoder for the time base is dirty, but I work with it regardless. Its not something I would ship back to Rigol because I think the older units with firmware 2.2 -2.4 ?? were made better and I fear instead of servicing it they'll swap a board or the entire scope for a newer model.I easily think the scope will last far over 10 years. IIRC in ~2011, scores of Rigol built Agilent versions, DSO3000 series, were dumped for $150-200 on eBay all working, the seller was offering a batch of them 10-20 at a time for almost a month; they were built in 2005 or so and were dumped by a school.Quote from: staze on April 03, 2013, 04:38:47 pm

I mainly use a Mac myself. Anyone know if something like LabView or any 3rd party software will talk to this scope on the Mac? It does look like it'll write out CSV to a thumbdrive, which a mac should read.Any thoughts? I know there was a guy in Germany, I think, that wrote a Mac application to access the Hantek.Thanks so much for the help. Now I'm leaning back toward the Rigol.

content: Quote from: EEVblog on April 03, 2013, 11:27:35 pmI'd disagree with the above statement. The cost factor for an after-hours tinkerer/hacker is a lot more important and the cash saved when buying the 1000-series can go into other kit like a good bench PSU, soldering iron, DMM, etc. I find myself in much the same space the original poster; by day I write C++ code for large unix systems used in the telco space. In the evenings I sit and hack Arduino and TI MSP430 code and build little projects from PSUs, chargers, NTP time-sync kit to a mpu-controlled electric blanket.Doing the above I find the 1000-series more than adequate for what I do (I actually have the Atten ADS1102CML of which I did a review elsewhere, but it's in the same class as the Rigol 1000 series). In fact, in almost a year of having this scope there's nothing I did that I couldn't measure with it.Quote from: EEVblog on April 03, 2013, 11:27:35 pmI don't dispute the above fact - and believe me, I drool over the WFU rate of the Rigols and Agilents, but at the end of the day, my current scope handles everything I throw at it. Having the extra cash allowed me some freedom to get my bench set up and kitted out with Raaco drawer systems, good LED lighting, a swing-arm magnifying light, etc.If you've got the budget, by all means go for the 2000-series, but if not, using the 1000-series for tinkering/hacking really does not present any challenges.--deckert

Keep the virtual machine for electronics except when working with PDFs. I find Apple's text rendering much better and the scrolling much more natural and faster than under a virtual machine or regular Windows. Get XP because it is compatible with practically everything and I am sure it will still be for at least 4 years.

content: Yeah, while a number of EE tools offer Mac versions (Eagle for example), you will eventually run into a situation where what you want will ONLY run on Windows. I use Parallels on my Macbook and like it a lot. With Coherence mode (same thing as VmWare Fusion), the desktops are merged and you rarely even notice the fact that some things are running in a virtualized Windows installation.I don't recommend trying to use the latest version of Windows with it - it works OK in Parallels/VmWare/etc, but some of the software packages you might want to run don't always run well on the latest and greatest operating system version. Stick with Windows 7 for the best experience. XP is nice and stable but it is very old and was supposed to be past support sunset by now. The only reason Microsoft still supports it is because there are so many holdouts still using it.But generally speaking, you can have the best of both worlds that way. When software you want to use offers a OS X version, then you can use that... and for others you can just use the Windows version without really worrying much about it.

If there's a firewall up, you're not advertising your computer to the public and you're not mucking about in the questionable corners of the Internet, the computer's a damn appliance, not a kingdom that needs to be guarded.

content: It's not just security updates - no more bugfixes or driver updates either. And once an update to that specialized software breaks backward compatibility you won't have much luck convincing the vendor to support your retired OS platform.Also, there are many ways to compromise your system other than visiting shady web sites. You wouldn't call this one shady, yet it is exactly the kind of place that would be targeted by a zero-day exploit such as the Flash or JPG exploits that have cropped up in recent years. And just because you aren't running a server doesn't make you any less of a target. Bots don't care.Personal computers are certainly not appliances. You can't have your identity stolen by a bot that hijacks your microwave. Yet.

content: Quote from: EEVblog on April 03, 2013, 11:27:35 pmThat's a little sad to read. As an electronics hobbyist (software engineer by day) I just can't justify spending around US$1000 for the DS2000 series - that is a whole lot of money on a hobby budget. At that price range, frankly I'd rather go out and get a super nice new RC helicopter for another one of my expensive geek hobbies.There *must* be a decent scope in between the DS1052E (US$300) and DS2000 (US$1000) which offers advantages to hobbyists while not breaking the bank. From reading these threads, it's pretty clear that I am not the only one with a budget that can only be stretched to around $500-$600, regardless of how much more value you get by adding 30-50% more (that's a game you can't win unless you won the lottery).I reckon that the DS1052E (which I have evaluated an older sibling of over the last week), would actually serve me fine for my journey beyond the simple DMM. That is, if it weren't for the fact that it sounds like a jet engine and has a screen no bigger than my smartphones yet a resolution 4x smaller.

Seems like it's all pointing at Rigol at this point, but just cycling around between "Buy a 1052, it's all you'll probably need" to "Save your money and get the 2072". And the 2072 does look sexy as hell, but since I'm not an EE, I'm just not sure if I'll use all it can offer. But then, I do like nice things (I bought a Fluke 189 for that reason), so...Now, I'm off to watch Psych, and The Daily Show.

content: Quote from: staze on April 04, 2013, 05:02:16 amThe only change I would recommend would be to get the 1102 (100MHz version). Many of the glitches I measure with the Atten come out at 60-70MHz (see the common mode noise glitches in the "show your bench PSU" thread) and some of the signal ringing a little higher.I also agree with MacAttak's earlier advice in reply #5, it's really good advice.--deckert

If you can't afford it, the point is moot.

content: I fond the DS1052E/1102E the best compromise between reliability and price. The model has been around for 5 years and during that time the software has been refined. Technical support and warranty claims have been reported by users online (just get Rigol products from authorized sellers).In my opinion, when you pay hundreds of dollars for something, you better know you are getting something you can rely on.The other oscilloscopes in the price range of this series are recent and sometimes unpolished. Little is known or published about them so you are not 100% sure what you are getting.I have more confidence in a tried and proven product than something little people know at this sort of price range.And don't forget that the more people are using it, the easier it will be to get people to answer your questions. Also, it's resale value is likely to be higher as there will be more demand for it, like happens with Tektronix CROs right now.Now the issue with the DS2072 is that if is twice the price and is not yet proven, although it's quality suggests it can overlast a DS1052E. And don't forget software will contain more bugs than usual for now.

And that's excluding the sexy options such as serial decoder, advanced trigger, etc.It does look like a great piece of kit but for many hobbyists who value their savings and marriages I think the 1052 will continue to be the Model T of the oscilloscope world for a while yet!

content: All very good points.So, the question becomes:Spend ~$330 now, and get a DSO1052 (or a little more and get the 1102), and have a scope that will probably serve for more than what I need right now (heck, I don't even know what I need, which is part of the problem), and in 3-5 years, upgrade to something better if needed, maybe recouping some part of my ~$330 by selling the 1000 series. Or save a bit longer, buy something higher end (the 2000 series) and have something that will last me longer, but may be way overkill, in which case I got something nicer, but spending way more.It's the "buy a radioshack dmm vs buy a fluke". Sure, the 'Shack DMM probably will do everything you want, but if you need a Fluke in the future, you're stuck with a Shack DMM that you either have to sell, or just look at thinking "why did I buy that?"But, I'm a tinkerer, so the 1000 series will probably work fine for me for everything I want to do. *sigh*At this point, I'm saving for anything, so hopefully by the end of the month when I have enough for the 1000, I'll have made up my mind to either buy, or wait.

If you are like me you change hobbies every once in a while. My only exception is electronics because there are half a dozen of fields I can alternate between.You can always sell your gear. The DS2000 series will probably keep its value more because it is new and likely to be in service. You can sell the DS1000E series as well but by then, the models will probably be discontinued.Weight the factors in. There are many ways to do this like pros/cons lists and such.Quote from: staze on April 04, 2013, 07:10:26 pmNah, a 'Shack DMM equivalent would be a DSO nano. This is more like Fluke 117 vs. Fluke 87V. You can keep the Rigol DS1052E and get a DS2000 series in 5 years if the 1052 costs too little to make the sale worthy.The DS2000 series have a Trigger Out. If you connect that to the Trigger Input on the DS1052E you effectively get a dual timebase 4 channel oscilloscope. Neat!If you feel you deserve a DS2000, get it. If not, get it when you feel you deserve it, if this becomes your permanent hobby you will eventually want one.Quote from: staze on April 04, 2013, 07:10:26 pmYeah me too. But I got this oscilloscope and I am expecting it to last until I graduate from college. I start in august and it ends 3 and a half years later.Another alternative to the DS2000 series is getting a DS1102E, a logic analyzer and/or an analog oscilloscope depending on what you need. As a bonus, it fills up your empty bench a bit.Ivan

I've always been interested in electronics, but I've never spent that much time learning them. Macro stuff I can do (home wiring, etc). Micro stuff I've always dabbled in (replacing caps on failed monitors, etc). A scope is something I've wanted for a bit, especially since my grandfather used to write the manuals for Tek scopes (yup, good ol' days when Tek was pretty much THE employeer in Beaverton, Oregon). =)One of the first things I was going to try to do was look at my home AC power for harmonics (looking for signals that would interfere with X10 type communication). So FFT would be needed, but the 1000 series does that.Think at this point, I'm going to just going to save, and figure it out once I have the money. I do need a bench power supply as well.*sigh* I guess the problem is... I'm not strapped for cash. I just have to save for it a bit longer (read, as you said, saving marriage).

Only thing that would be awesome from the 2000 series (other than the much better screen), is the serial and I2C decode, but those are pay-for options anyway (after the 30 day trial), and I can't see using those at the moment anyway. *sigh* Not being an EE (hell, I got my degree in Political Science (aka Government))... gar. The 2000 series is hella sexy... damn pre-emptive buyers remorse. =)So, what KILLER "app" or feature does the 2000 series do that the 1000 series won't?

Not to be against you Dave, just a suggestion.Ethernet might attract someone who's into IT. I admit that.If you decide for the DS1000 series, you could get a logic analyzer as well, as you go along. A Saelae Logic as Dave reviewed, is a good idea if you ever want to program microcontrollers. If you are a programmer, I really recommend getting into MCUs. I wish I had the talent to program properly.The DS2072 is great stuff, in my opinion. If I ever get a chance to select my equipment for my lab in a company, I would definitely get one of those.

content: staze, you keep mentioning that you also need to get a bench PS. Do you not have one at all? If not, then IMO that's a pretty darn critical piece of equipment for most of us - on par with having a scope and only slightly less important than having one or two DMMs and a soldering iron. I would do some homework on that and pick out what you think will suffice for your needs, and keep that in mind as you consider budget for the scope. Bench PSU costs can vary greatly depending on what you need out of them.But if you already have a PSU and just want to upgrade it or get a second one, then it's not such a big deal. As long as you have *something* capable of delivering an appropriate source of power for what you are doing.FWIW, I was strongly considering the 2000 series too when I decided to go for a 1052E. The money actually isn't a problem for me in general - it's just that overall I have poured a ton of cash into this hobby over the past 6 months. At least $3,000 - not including the new scope - on things from PSU to solder and hot air stations, assorted power and hand tools, furniture, books, educational kits, mcu boards and modules, countless online orders for parts from Digikey/Adafruit/Ebay, PCB fabrication for circuit designs, and even a mid-size 3D printer to handle creating custom mechanical parts and project enclosures. All those little things add up very quickly.I rarely lose interest in my hobbies, and within a couple of years I'm sure I will have outgrown this scope. So when the time comes, I will just buy a better one - but for now, the 50MHz low-end 1052 will do, and it is much more easily absorbed into my budget.

I mean, that's a whopping €561/$719 price differential here! I'd like something a little better than the 1052E yet not as overkill as the 2072 which I would probably never use to its fullest (and couldn't justify getting).Thus, the Owon SDS7102V remains of interest to me. At €489/$627 it sits under the middle marker between the 1052E and 2072 (and qualifies for free shipping, unlike the 1052E). Forgetting the 2072 for a moment, don't you get very interesting features in the Owon for the extra 70% over the 1052E? (10x longer memory, larger screen, one ADC, lower noise, portability, better probes...)I'd be interested in trying to highlight the candidates in this €400-500/$500-600 range and judging by some of the other comments in this thread, I am not the only one.* Prices from batronix.com, the cheapest source in Europe.

content: Quote from: ivan747 on April 05, 2013, 12:46:35 amYeah it's pretty clear that a stand-alone logic analyzer is much better value than  integrated ones, and more likely to receive software updates. I noticed that after the Saelae Logic16 was introduced, the Logic8 is now only €119/$149. Being a software guy, having native client software for Windows/Mac/Linux is pretty awesome, as is having official access to anSDK.Biggest downside appears to be that the voltage levels are quite limited, meaning classic rs232 signals are off limits (you'd have to build a small frontend with voltage dividers and potentially some inverters).

With one channel use it can do 1GSa/s using 500us/div - 2ns/div and with 2 channel use 1ms/div -2ns/div 500MSa/s for both channels.Siglent: With newest FW they are not bad. It is good to realize also that old reviews are old. Building quality in outside and insidew is also good in new SDS1000CNL/CML/CFL models.UI is quite fast and good features. Even there is real dual timebase! This means that in ALT mode both traces have own trigger AND also separate timebase! There is also trigger for both edges. Of course vertical have fine adjustment also. Factory tell waveform update rate is 2000wfms/s max. Equal time sampling also works fine with new FW. Both channels have also separate adjustable DSP filters. Good measurements and also tracking cursors etc.(These old 5.7" display models are going Obsolete and Siglent stop them after 30.April.2013).Siglent CML models have max 2M shared capture memory and it is half speed as example in Rigol DS1000E series where is 1M. For low speed Record some Siglent models have separate 6M memory + very low speeds it can also capture directly to USB memory. (of course it have also this usual recorder as "frame record" for higher speeds but it have (as usual) dead time between frames. (6M recorder is continuous data stream without breaks but can use only with low horizontal speeds)Siglent have also developed they after sales customer care (Of course distributors need be main role for after sales care). Example public FW updates, service manuals and also spare parts available.If look more expensive scopes. New Rigol DS2000 series looks very good.

I am interested in the line with extended memory (good for capturing digital communication) soCMLis the one for me.There's a decent demo video online, which shows off the Siglents 1052E heritage, except there's now a dedicated single shot button, no need to share the vertical control between the 2 channels and of course more horizontal pixels (more visible waveform history). It has soft rubber buttons, 12 of which are with status LED's. I also like how the vertical resolution dial takes precedence (larger and located higher up) of the offset dial, which confused me on the Rigol 1052E.I just wish I didn't have to order from China, but I have not located a European dealer yet.

content: Is the CNL the same as the CML?Note there are CNL's on eBay.I don't know if there are any local dealers since it's the OEM building and reselling them under their own brand... their clients might get a bit upset.As much as I/we bitch about all of this, it's still mind blowing that you can buy ANY scope for $300-400. Wonder what Tek thinks about all this. Having worked for 3com when Netgear and Dlink really made their push with $20 NICs, they were pretty honest saying "cards are cards, it's all about support". Unfortunately, they were both right and wrong.

content: If you have a retailer near you or a good online vendor, most will let you try it for 1-2 weeks, no questions asked return. Then you can have the 1000 series scope now or sooner, than wait a longer time to acquire a more costly scope. You get more for your dollar in the 2000 series if you have more money to spendandyou need those functions. But until then, you are taking a gamble on whether your skill set for the near future will appreciate those extra capabilities. Only you can answer that question. If that time comes, the 1000 series is popular enough to easily sell; just note those that have been sold on eevblog by members and how long its takes to be sold. On eBay, I see them sold used on bids for about $300, for new ones selling for $320! Its certainly held its value.http://www.ebay.com/csc/i.html?LH_ItemCondition=4&clk_rvr_id=467640924211&_nkw=1052e&LH_Complete=1&LH_Sold=1&rt=nc

But yeah, I know there's the question of if I'll really grow to use the 2000 series, etc. I think what I'm really going to do at this point is save (if I can... I keep finding ways to deplete my savings) until I have enough for the 2000 series, and at that point, I either buy it, or buy the 1000 series and some other stuff. Or, I'll have moved on in hobbies (I hope not). Who knows, maybe by the time I have that money saved (July/Aug), the price will tick down a bit. Looks like Instek and a couple other manufacturers have brought out scopes that may force Rigol down a little bit (maybe).The 2000 series is just too damn sexy to NOT want. The intensity display was probably one of the biggest things that sold me... that and the wfps, etc.Here's hoping, and thanks!

SDS1000 series is not anymore newborn baby.Last time I have only very quick test SDS1072CNL with newest FW version 5.01.02.13.Not bad.-----------------------------------------------------ADD: Here you can find more new freq response test for SDS1072(CML)BW is clearly improved in new HW. (also Equal Time mode is now lot of better in new FW (+HW))https://www.eevblog.com/forum/testgear/siglent-scopes/-----------------------------------------------------Next images are from OLD tests using older SDS1072CNLFW: 3.01.01.31R17HW: 10-61-3.3Frequency response -3dB point is (dependent about test setting) between 90 - 100MHz.ADD: -3dB point is around 115-120MHz in new HW 11-61-3.3Risetime using not so perfect <1ns risetime pulse.same as before but persistence on (there can see also cursors are auto tracking)Freguency response using linear sweep from 1MHz to 150MHzCenter is 60MHz and 15MHz/div. In this image -3dB is around 90MHz with this test setting.(signal from generator using 50ohm coaxial and Tektronix 50ohm terminator in scope input. (this is not ok becouse total load is not 50ohm impedance mainly due to oscilloscope parallel capasitance. But accuracy "enough for this purpose".)random imageand if some reason do not like black backround....What is nice, it havedual timebase. In ALT mode both channel have of course individual separate trig, but also they may have different timebase.If compare to Rigol DS1000E serie and if I remember all enough Siglent have more features.(time ago (some year) I have also sold some Rigol DS1000E series and also tested them. With this experience, in this price class Rigol DS1000E was good and when it come to markets there was not so many others. It was first chinese DSO what quality I can accept also for sell to my friends so that I can also meet them later without need later run away.)Everyone have its own needs and liking and financial situation. This is my personal opinion and NOT related to situation that I sell also Siglents. I'm hobbyist and professional with measurements and electronics and selling is only very little sidecar and not so much business as "get all money you can"... no no and no.If I get today nearly same price SDS1072CML or SDS1102CML as Rigol DS1052E or DS1102E.Selection is very very clear and I select Siglent without hesitation. (yes and I have both available as easily)One I must say, Rigol probes building quality is littlebit better than what Siglent use (these what I have seen. Yes they work and no problem. I littlebit worry this rotary cable connection in scope end - why it is this rotary construction. Fixed is more reliable imho)Of course there can do many kind of playing, one example with edge ?? trig:(In this image used dot mode instead of line)(there is 8ns "jump - no jump" jitter in signal timing, and also then added level jitter. Trigger is some rising edge (left) before display area and trigger mode is of courseedge ??))Some more can find herehttp://siglent.freeforums.org/index.phpbut sorry there is finnish language also. (but least some test images may show something more. Later I will continue with some more tests.

Heck, I wouldn't even call mine "loud", it's just "louder than I would have thought for the device". Heck, old Analog scopes were certainly louder than this (my Drobo is louder than this, but it's still noticeable).Either way the serials work, mine would seem to be a later production than yours. So I doubt that's it. I just figure in 6 months or so, when I know this thing is past it's likely early failure time, I'll pop it open and drop a quiet fan in there.Now, if we had some db meters...

But mine isn't the bearing, it's just air flow noise... which is probably mostly caused by it being a 5500rpm fan (which seems crazy to me), and the air movement past all the grills. The only thing I can think is the "quiet" ones are the odd ones out, and they used a different OEM for the fan, or somehow set the fan voltage lower than the 10v or whatever someone measured was being fed to them. Anyway, not a huge deal. Just seems like something that should have been caught in their engineering phase (or at least in later revisions).

content: Quote from: Galaxyrise on October 16, 2013, 04:52:16 pmWell, I bought the DS1052, and work bought me the DS2072. =) So, it's still valid. =)I really liked the DS1052e. It worked. It was simple, did what it should, and was really inexpensive. Used it to fix several pieces of equipment.Yes, the DS2072 is better. Is it worth 3 times as much? I don't know yet, but with how much I've used it, maybe not, at least for what I do with the scope (electronics repair). Yeah, a $100 analog scope would have worked too, but I never found one I really liked for that price point.What really muddies the waters is the new DS1000z series. 4 channels for $500 (if you include the tequipment eevblog discount)! And for not much more, you get an AWG. Crap, my bench (shelf) would be much less cluttered! =) I haven't used one, so who knows... but given the specs, I wouldn't hesitate a moment if it was my money. I'd grab the DS1000z and never look back.But, if you only have the $300 like I had... I wouldn't hesitate a second to get the DS1052e unless you have some big need for the extra features of the higher end scope, or just hate buying older tech. The 1052 served me extremely well. I'm still not sure if I'm going to sell it, or keep it around (I could easily use it as another two channels by linking it to the DS2072).Hopefully that makes sense. I can't really speak to the difference if you're doing higher end work, but for repair... depending on what it was, you could probably buy the 1052e and make that money back just on the hours billed for the repair. =)

content: The DS1000Z looks like the one I have been waiting for. I wish there were a 2-channel DS1000Z version as a direct replacement for the old DS1052E, but at €535 the DS1000Z is a lot more affordable than the €845 DS2000 (Batronix prices).

content: You get your money's worth as you buy up the Rigol family of scopes. If you buy just what you need you get the biggest bang for buck. Glad to see Rigol is innovating as best possible on the low end too.Note, on the 1000z, per the specs, at 4 channels, the max sampling rate drops to 250Ms/s.

content: Well, the 1GSa/s ADCs are available since 1997 or so (remember TDS220), but they are still expensive.

content: Those were not off the shelf ADCs, and used an analog shift register as fast in, slow out FIFO, so the actual ADC did not have to run at 1 GS/s.
