content: Yep, what you say in the video pretty much sums it up for me also.I bought the DS2072 for the same reasons as an entry level scope. And actually, I don't think I will need to get an other scope, as a hobbyist. Maybe, IF one day I will advance my knowledge level enough I will need a Mixed Signal Oscilloscope but for the next 10-15 years I am well covered.My only complain against Rigol is their support (after sale service, firmware updates).The competition from the other major companies demands a far better customer service, they should invest more effort and fast into this matter.George

content: Dave wants Staze to go brokeI would still get the DS1102E for myself (and I did). You won't convince me this time Dave.It's just that $800 is alotof money for a hobby you can abandon in 2 or 4 years.I can't abandon the hobby myself because I am making it my career but still, I don't spare $800.Original thread here:https://www.eevblog.com/forum/testgear/first-scope-lost-in-the-reviews/P.S. now the poll made in the original thread will go frenetically towards the DS2072. Lucky Dave.

Saleae continuously reads the bus at 24 MHz, which exactly twice the USB 1 (full bandwidth) signal rate. On the other hand, sniffing USB 1 may not be all that useful in this day and age, unless maybe you're developinganotherUSB bitbang implementation from scratch.

There you have a difference from $3800 for the Rigol and about $7000 for the Tek ones.Its pretty scary how this development is going....

content: Quote from: EEVblog on April 06, 2013, 09:25:00 pmNice video, Dave - thanks for the kind words about the softwareOne minor mistake while you showed the DS2000's features - in frame (segment) analysis mode, you can work with masks (Pass/Fail) or templates (Trace). You can't chose a frame to use as the mask, as you tried to do in the video (you just create the mask in the traditional way of X/Y div/distance) - but youcando it if you use templates. Working in Trace mode is more powerful than Pass/Fail since it analyzes and displays both error frames and the percentage of difference (deviation) from the template - whereas with masks the difference is always just 0% (pass) or 100% (fail). This makes the Trace mode a nice tool for analyzing things like jitter.In any case, great job

content: Quote from: casper.bang on April 07, 2013, 09:55:09 amBut the quality/features of the DS2072 are, as Dave put it, an order of magnitude higher - more like x10 as opposed to x2. But of course, many other factors have to be considered: How quickly do you need a scope? How often will you use it? What are your long term plans? Etc.Need the cheapest scope as quickly as possible?A used analog scope or one of the low cost DSOs is probably the answer.Saving money for a scope that you don't need immediately but want to use for years?Don't bother with one of the < $400 DSOs anymore - they're outdated. Save your money a bit longer and get something vastly better.One other point that I don't think Dave mentioned in this video: the quality of the build (inside and out). Much much better on the new Rigols - it feels much closer to professional measurement equipment.

If you're passionate about this hobby, know that you are in it for the long run and have the cash, I can totally see the benefits!However, if you're like me; primarily a software engineer with a neglected but curious electronics past, occasionally tinkering with breadboards and can see the advantage of a basic scope over an advanced multimeter, there is a mighty big step from a 1052 to a 2072. I am in the marked for an beginner/hobby scope that improves on the 1052 for around $US500/€400. By several definitions, the 2000 series is not that.

Well, if you don't need to do much/any digital circuit debugging - and the current noise issues have been resolved - the Owon SDS7102V is a good deal (large screen, 10M per channel, battery-operated, VGA out, etc.) in that price range.

But yes, with the DS2000, there is the update speed, the segmented memory capture and analysis, the vast array of triggers (including protocols), and the optional protocol decoders - all of those are nice aids to have in digital design and debugging.I don't really know much about the Siglents, but I'm sure there is tons of info scattered about this forum

content: Quote from: casper.bang on April 07, 2013, 02:42:54 pmI have bought both of these scopes for our school (and, actually both are the low BW model with a SW upgrade - it's a bit cheaper that way - I think Dave might be wrong about the SW upgradeability of the 2000 series). The DS2000 series is sexy and definitely pornographic. Looking at the DS1052 screen is like watching an old time peep-show with a scratchy B/W photos on a Rollodex type projector. That said, I am not sure I will be able to justify an additional DS 2000 series scope when a DS1000 series with a nice LA (we use the DV3100) costs the same amount. Most of the time the scopes are used to see if we have a reasonably clean waveforms without too much undershoot/overshoot, or if the edges are monotonic and somewhere down the line there is no double triggering of F/Fs. In this respect both scopes perform similarly. I swapped around the probes that came with the scopes and I really can't tell the difference. And all the options (the bus decoders, the fancy triggers and the 56M memory) on the DS2000 series are not that cheap. So if you are doing digital design, I would be tempted to spend the $400 on a nice LA (the DV3100 with 512K memory on all 16 channels and compression on top of does the trick for us).

One thing though (and I think Dave got this wrong in the video), I'm pretty sure all of the DS2000s come with the 350MHz probes - regardless of the BW of the scope - but I don't remember the probe BW of the DS1052s.QuoteAre you aware that's it reasonably easy to just keep restarting the trial period for the options in the current firmware?

Combine that with anti-aliasing and a scope with these feature is more fool proof, and should be the new beginner standard feature set.You could argue that the 1052 has more traps for beginners in that respect.It's not always all about price.

It will interesting to see what happens now that the GW-Instek GDS-2000A has entered the fray. The 2 channel versions are priced almost exactly the same as the Rigol DS2000s - but the 4 channel versions seriously undercut Rigol's DS4000 prices - and actually create a whole new price point for a modern 4 channel scope with intensity grading, expandability, etc.

content: Hi All, My search for a new scope , lead me to many reviews. and I learnt , what was important,Digital, deep memory, bandwidth, sample rates, screen size, quality and costs.I first looked at Rigol 1052E , then was thinking of Owon, almost ordered. Then update rate after watching Agilent's video on need for fast update to catch rare events. I learnt that Rigol was source of low end DSO for Agilent and I almost bought the low end Agilent on special. but then came the DS2000. It had what I was looking for , and I think Rigol learnt from Agilent.I compared the cost of Rigol to the Agilent and said ok! Maybe I jumped at it early, but bought the DS2072 back it Aug/2012.Definitely NO Regrets!!!!!I was just helping a friend debug data stream and It was easy to show 24 bits on the wide screen, He commented his company using Tek had such small screens. I still have lots to learn with all the OptionsAnd I thank Marmad for the Great software to connect to my DS2072, for quick captures to forward on to people with such easy.Below are some pics of my playing with the DSO and Marmad's software (already posted on other thread)

content: Quote from: majki on April 07, 2013, 11:07:32 pmIt's true - but it's limited in another important way as well. Sometimes you want to use segments to quickly capture multiple occurrences of a signal (e.g. an edge or a pulse) and then run an analysis on the segments to see if there's any minor deviation. Well, the waveform update rate also affects how quickly you can record segments - the minimum rearm time. So the Agilent X3000 has a minimum rearm time of 1us for segments (1/1000000) and the X2000 and DS2000 have one of ~20us (although the DS2000 can be as short as ~17.5 us when you use the Auto sample setting). But the DS1000 would have a much longer rearm time - something in the millisecond range - making it much less useful as an analysis tool. Also, I don't remember if the DS1000 time-tagged it's recorded frames or not - which is rather critical if trying to use it for debugging.

content: Quote from: DL5TOR on April 07, 2013, 11:54:47 pmThat 1ms will be a delayin addition to the rearm timeplus the acquire time, I'm fairly certain. You can test it easily to find out. The DS2000 lets you set that added delay down to 100ns - but that doesn't mean it can capture segments that fast.The general formula for figuring out the minimum time between segments is: rearm time + (timebase * divisions) + delay setting.

It came handy to me many times when I had the hacked 1052E. Don't know if some spec or feature like the hi-res mode covers and renders it not worth including in the 2K series?Anyway, selling the previous and upgrading to the new was a good move I don't regret.

Yes, hacked option and all that, or get it legit for the same price as the 1052E was a few months back.What's the collective thoughts on benefit of the 70MHz versus 100MHz or 200MHz - not everyone has Dave's budget (certainly not as an enthusiast) or contacts to get great deals (but if you do, share them O0 )

content: Quote from: DL5TOR on April 08, 2013, 12:46:59 amThanks for the test, DL5TOR. It seems to show that the rearm time is included in the delay time - I haven't experimented enough with the DS2000 to see if that's the case with it as well. But I think your timing experiment has too many unknown variables to get a truly precise idea of the rearm time. For example, the difference between the 1ms setting and your calculated 1.25ms per segment is 200 waveforms per second. That might not seem very much, but at the lower end of the update rate spectrum, it makes quite a difference (average test time to see a glitch occurring 10 times per second [with 99% prob.] doubles: i.e. increases by ~2 hours). You might try the experiment again - at 200ns/div and at 2ns/div to see if they substantially alter the final result.The problem is, as mentioned before, since 'recording' takes place at trigger events (except in P/F mode), without accurate time-tagging of captured segments - or good analysis software to use on the segments - the usefulness of the feature is quite limited. That is likely the reason you don't see much mention of the feature in the DS1000s.Edit:As an example, here are two plots of segments from the DS2000 - that show a sine wave glitching into a square wave. The top one is done without using time-tags - and the bottom one with. It's clear that in the bottom image you get an idea of when the glitch actually occurred in the given period of time.

(The 'scope display has a black background and a yellow trace, but the saved image inverts the background to white and makes the yellow trace more of a brownish color.)And, by the way, Dave's waveform shows well over 100% modulation -- quite recognizable through the little "blips" instead of a narrow region of 0 voltage. The attached image is about 98% modulation depth.

I mostly still run older equipment for my repair shop and the students where I work are still using HP54603B's which are getting a bit outdated, just how much outdated I was unaware of till watching the Rigol and the price is great. My only concern is how they might hold up to the abuse of college students so we were leaning towards the Agilent DSOX2002A since our HP-Agilent scopes have had a pretty good track record. It remains to be seen if anything new will hold up to these kids. I get lots of good ideas from your test equipment blogs that help keep me current.Great jobCheersPhil

Tear downs are good but ill be honest, I don't walk away with nearly as much learning.I've had this debate in my mind about scopes, I have this massive tds544a at home it's a real top spec scope for its time 500mhz, 4 channels, lots of good stuff. Most of it I don't use and would rather have something small and portable. Was looking at Agilent dso2000x, Rigol and Hameg. After seeing the video I think my mind is made that rigol is a awesome scope dollar for Dollie. Agilent is good too but probably pay more for the name. Tek IMO is really just a name at this point...

content: The software looked interesting, but I was shocked by how long it took to transfer from the scope to the PC. It was attempting to transfer the contents of the 14Mpt sample memory(before being cancelled), right? Eight bits per sample, right? That's 14MB of data. At 100BaseT you get around 10MB/s of throughput ... so it should have been able to transfer everything in under 2 seconds.So, is the speed a limitation of: the bloatedness of the LXI protocol? the scope? the software?

content: Quote from: kfitch42 on April 10, 2013, 05:55:01 pmTwo things:1) Your memory estimate is way low. Dave was working with segments - and together with the full 56MB of normal sample memory, the DSO has something in the neighborhood of 128MB of memory for segments.2) The DSO treats each segment as if it's a single-shot sample, so when external software asks for the current contents of memory, it gets ONLY the current segment. The software then has to ask the DSO to 'play' the next segment (and wait) - and that's what takes most of the time - not the actual transferring of data.After Rigol's experience with the DS1000 series - where you could cause major refresh glitches in the DSO by asking for data from it too quickly - they have (rightly so) made it impossible to cause any kind of glitch or slowdown to the scope's operation remotely, so external software always has low priority. Otherwise I could easily get more than 20 fps from the DSO for real-time waveform display.

content: Quote from: marmad on April 10, 2013, 06:19:35 pmAhhh, I guess I didn't understand segmenting. I assumed there was a single pool of sample memory that got segmented.In the video he captured 8128 frames of 14Ks each. That works out to about 113MB (I was only off by less than an order of magnitude. So, it seems that the combination of the protocol and the scope (I agree the scope should put external requests at low priority) is the limiting factor. I guess that isn't anyway to 'pipeline' those requests ala HTTP/1.1

content: Does the 2072 use compression as well as segmentation? As a software guy working with smart-meters and the analysis/storage of massive amounts data, I would say that timeseries data on a small scale (i.e. in an oscilloscope) is no different and thus subject to some of the same efficient integer compression techniques.

content: Quote from: casper.bang on April 10, 2013, 07:13:39 pmI don't know the answer, but I am guessing no. The great thing about compression is that you get to store more data that fits the expectations of the compressor. The bad thing about compression is that it is less predictable. On a bit of test equipment like this you should expect your expectations to be violated. With compression you would never know how many sample/frames you could store ahead of time. Is some white noise sneaking into that signal you are debugging? Suddenly you don't get as many frames (or perhaps your update rate goes down ... something will have to give).Perhaps compression could help when transferring data to the PC, but, as has already been noted, the performance there is not limited by the data throughput.

content: Quote from: kfitch42 on April 10, 2013, 07:03:04 pmYes, it's a pity that the DSO can't just transfer large blocks of memory with markers signifying segment start and stop points - having to display each segment on the DSO screen really slows down the process. The fastest speed I can extract segments from the Rigol is, on my desktop machine, about 1400 per minute for single channel / 1100pm for two channels. But currently my software is the only way to get segments out of the DSO (which is why I started writing it in the first place) - that is one feature that is lacking in the current firmware: the ability to save and load captured segments. It would be nice if Rigol adds it at some point.Quote from: kfitch42 on April 10, 2013, 07:23:55 pmAlso I'm just not sure it's possible to do real-time given the tight limitations of maintaining the waveform update rate (and blind times). Each segment is exactly like a single-shot capture - and at the 20ns timebase setting - which is where the Rigol captures ~50k wfrm/s - it can capture segments at almost exactly that rate. But I don't know for sure how it stores and accesses them inside the scope - but I sure would like to

content: Quote from: kfitch42 on April 10, 2013, 07:23:55 pmOn the DS7072 as I understand it, capture/analysis, storage and presentation are after all very different things though (unlike the cheaper scopes). In loss-less software algorithms (image analogy: PNG/GIF/RLE) we deal with worst case performance (big-O) and I would think it's easy to guarantee some minimum, or worst case, simply fall back to non-compressed (image analogy: BMP/RAW).From the demonstration video by Dave, it looks like compression could potentially store several order of magnitudes more frames. That could come in handy in a scenario where you favor longer memory over higher frame capture.

I keep thinking if i go with the Agilent I might as well get the 4 channel version which is like almost doubling the cost. With Agilent you start adding options the price starts to go way up and quick.I also keep thinking (pure speculation) that Rigol is going to come out with the mixed signal version of the DS2000 series.
