I ran more tests than what made it into the final edit!

I'm responding to this comment in your Agilent review video:
'And I just did a second one (test) and it also took about a minute, so you can actually conclude that this Rigol, if you do the math...  that's just over 800 waveforms a second...'
This is incorrect.

I have not seen any credible evidence anywhere as to a several hundred wfrm/s rate for the Rigol E series, and in fact, all of the circumstantial evidence (wfrm/s rates of similarly priced or designed scopes -  and much more expensive scopes) points to a much lower rate.

But I'm certainly open to hearing about any highly intensive tests that were run (as I did with the Owon SDS7102 and Hantek DSO5062B).

Hi Dave

Any chance You will look into 12bit HR mode of DS2000 series ?
Still not many info how in real this all HR stuff on scopes is working.

Seems that it is going to be very long review..... ;D

6:50 "Pleas don't remove the U disk..." I'm wondering why they didn't spell out the word USB.

Aha, this is because in China USB thumb drives are referred to as "U disk" so my suspicion is that the software was written by a Chinese programmer...

A big thanks to Dave and Marmad, I have learned a lot more about capture rates since reading this thread.  One thing Marmad don't you agree with Dave that triggering is the way to find the glitches?
By that I mean using the pass fail method and letting the scope find the glitch? The whole idea of one glitch a second does not seem typical, it may be one every hour, how does 1mwfsc help in that case, you would be waiting for months by your calculations.

Triggering is not a way to find the glitches, it's a way to examine them once you have found them.
Triggering on something you don't know exists doesn't work (or is just pot luck).
And if you are able to trigger off them, then the update rate is not relevant, because it's a single shot trigger.
Fast updating (and persistence mode + peak detect) is a way to find glitches and other things that you don't know exist, but you suspect might be there.
Having an analog scope is not magic in this regard, as you can easily miss glitches and runt pulses, even if you have the brightness turned all the way up. So in many cases, a digital scope with infinite persistence can be far superior than an analog scope in this regard. Even one with relatively poor update speed (if you leave it looking long enough)

Dave.

That certainly sounds like the best way Dave but don't you think the Pass/Fail could also work?
I imagine that on a low end DSO that's going to run into the same capture rate issue??
BTW Dave can you setup a standardized test on a video that anybody with a DSO and a arb generator could use to test their scope?  It would give all of us great data to publish in the videos forum thread and since you have several dso we could see how our cheapies stack up in an apples to apples comparison of wfcr.

My second comment on all of this comes from 15 years of doing repair work.  For me weird Glitches were very rare in the repair world and when I did come across it; most of the time I could just use my old Analog scope and Tap or twist the board and bingo the glitch would appear or disappear.

Repair work is a very different beast than development.  Glitches of the type that a high waveform capture rate helps with are almost exclusively caused by design errors not hardware failures.  If they show up in the field, it means there was insufficient testing for e.g., timing variation vs. temperature and you should just send the board back to the designer.  As a corollary, a glitch that results from a design error cannot usually be fixed by swapping out with a known good board so you really have to find the problem.

This is why I maintain that DSOs are not the automatic instrument of choice for all Electronic testing.
The features which are essential for development work,are pretty much incidental for most repair work.

Of course,most people in the maintenance side have been confronted by non-functional new equipment.
As you logically assume "It must have worked once", it takes some time before it dawns on you that they never could have worked.

In many cases,it is not cost effective to send them back,& the "Technical Assistance" from (guess what country?)
is useless,so repair morphs into development,where all the "bells & whistles" of a nice DSO would come in handy.

These are very much the minority of cases,in most circumstances the "bash the board" trick works.

I wonder always that the discussion about wfm/s starts in many forums again and again and reveals the lack of knowledge about digiscopes' basics. The Pass/Fail test is intended to be used to find deviation of a waveform and to define a tolerance band around a given signal. It never can replace methods searching for outliers and there are a few reasons why.

Let's assume to have a simple sine and a tolerance band of 100mV necessary not to trigger the fail function caused be noise - a glitch of 99mV would not be detected even when it appears.

The other reason might be that a mask has absolutely no influence on the screen refresh rate. Coming back to the example above, even if the tolerance band would allow a 50mV band around the sine and the glitch has got an amplitude of 99mV what if it appears in the dead time between two following screens? Your mask won't help because the scope's refresh rate is to slow.

Catching a glitch with a digiscope in persistence mode always deals with the probability to detect it between two screens - and the probability to detect it raising with the screens taken per second - the wfm/s.

In the past Agilent has made some detailed reports about this issue with the calculation done for scopes with low wfm/s and higher wfm/s. It reveals simply how many hours you might need to get seldom glitches with the slow scopes.

Nothing to remark according triggering on glitches - Dave has already mentioned the details.


Kind regards

The video almost inspired me to try one, the Rigol DS2202, the 200 MHz oscilloscope.  I liked the wide screen, reminds me of the Agilent DSOX.  Rigol of China has limited the sales of their latest Rigol DS2202 away from E Bay to protect competition from their dealerships in the U.S.A.  The Rigol DS2202 is not available in E Bay.  The Rigol DS2202 is priced $800.00 AUD in Australia as Dave Jones mentioned.  It is priced more in the U.S.A. at distributors in the U.S.A. for $1,600.00 USD.  I do like the angled design panel and the large wave form play back knob, remind me of the Yokogawa DL1502 oscilloscope, but the Yokogawa is an obsolete amber tube display oscilloscope.  There are flaws in the Rigol DS2202 as you shown in your video.  Rigol seems to be trying to update or improve their firmware.  I am happy with the Rigol 1052E.  I would like to try the little more priced Rigol, the 1102E.  I like Yokogawa, but I cannot afford them.  That 100 millionth picosecond is neat in the Rigol DS2202.  Thanks for the video, neat.  For my use, LR of geophysics metal mineral locator coil testing with signal generator, I do not need a Rigol DS2202.

I agree exactly with what Dave wrote in his last comment about triggering, fast updating, and analog scopes. Also with the good points made by ejeffrey about development work vs. repair work.

That certainly sounds like the best way Dave but don't you think the Pass/Fail could also work?
I imagine that on a low end DSO that's going to run into the same capture rate issue??

The Pass/Fail test is intended to be used to find deviation of a waveform and to define a tolerance band around a given signal. It never can replace methods searching for outliers and there are a few reasons why.

I'm wondering if what I wrote earlier about using a Mask test was misinterpreted. I never intended to suggest it was a method to search for glitches - in fact, just the opposite: it's a way to prove how bad the scope is at 'seeing' glitches. But this has to be taken with a grain of salt - since the Mask test adds overhead to the software before screen display, it normally decreases the wfrm/s rate (although Agilent claims that the 2000/3000X are the industry's only scopes to do the test completely in hardware, thus negating the time penalty in the 2000X). But in the case of the Owon SDS line, the wfrm/s update rate is tied to the screen refresh rate so the Mask test does not alter it substantially.

The Rigol DS2202 is priced $800.00 AUD in Australia

Huh!?! Please point me to an Australian website selling the DS2202 for $800 immediately - because it's twice as much everywhere else on the planet!

Hello everyone,

I was hoping you guys could provide me with some feedback:

I am looking at purchasing the Rigol DS2072 but I am a little hesitant as i am not very familiar with the Rigol brand. I have been doing a lot of researching and so far i am impressed with the specs and the current hardware quality of the DS2027 based off Daves tear down video and other peoples comments; but I don't know what to think of the product in terms of Software.

It appears that  the computer software isn't as nice as some of the competitors and watching your most recent video Dave, it does seem like there are some firmware bugs that still need to be worked out.

However I do like that fact that it does have the 8.5" screen, Trigger on Serial data, 2GSPS, 14MPT memory, 500uV/Div range and the record/playback function.
I also like the fact that the standard scope probes are relatively cheap in case replacements are needed.

The other model I am looking at due to my budget is the Agilent DSO1072B, it has the same bandwidth but 1GSPS and only 16K memory. From my experience the Agilent software is spot on and the products has a good reputation.
What I like about the Agilent is the waveform Zoom Simultaneously feature along with the look and feel of the product I also like the Waveform math and FFT feature. 

Does the Agilent offer a record/playback feature? Would that be apart of the "Sequence mode for easier debug" feature that they have mentioned?

I would consider the DSOX2002A  series which has the 2GPS, 8.5" screen and 100Kpt memory but that is out of my price range ad an additional $200+ I know you can get the function generator feature also but unfortunately I have to draw the line somewhere and that is at the $1000 mark.

Even though I am not overly concerned the overall size. Would the size of the Rigol be noticeable on a small work bench? As my work bench is relatively small it is something I should consider but is of low priority. 

What are peoples opinions on the quality of the Rigol scope probes vs Agilent scope probes is there a quality difference?

Aside from the spec difference between the DS2027 and the DSO1072B how do you guys think the features of the two will compare? are there any features that the Agilent will have that the Rigol wont?

Thanks in advance for all your input/opinions I really appreciate any feed.

Jeff

Don't buy the Agilent DSO1072B.

It's a rebadged Rigol, but with 70 MHz bandwidth instead of 50 MHz. Same as DS1052E/DS1102E, but with a huge price premium. In fact, I think they don't even have the 1 Mpt memory like the DS1052/DS1102E have.

Yes, Agilent trust Rigol for making their low end scopes.

That should give you an idea about the quality they have.

I have a DS1102E and I do like it. It's a very capable scope.

I agree. You are just buying an overpriced Rigol.

The DS2000 is an awesome scope for the money, it's got to be the best value scope in that $800-$1200 price range.
And I'm sure the software bugs will be fixed, if they haven't already, I'm just waiting for some updated firmware to see if it fixes it. John South said he'll have some more new firmware today.

Hi Jeff

Record/play back is called segmented memory in the Agilent world, I have it on the 3000 series scopes at work.
It is a charged option.

Yokogawa scopes also have this, and is standard.

I did hear lower end Agilents were repackaged Rigols but I was under the impression that was a few years back and might not be the same anymore.

Has anybody identified which Agilent models are repackaged Rigols? Does Agilent simply load its own firmware onto the devices or does it even use Rigol firmware (with slight modifications such as changing Rigol to Agilent in text)? Has anybody purchased a Rigol scope that can be repackaged and try loading the Agilent f/w into it? (just some thoughts)
If the Software is better (more user friendly, less buggy) I could see a bit of a price increase but I dont know about double the price.

I was looking at the DS1102E but I was under the impression that it was a few years old and was hoping for something which had been released fairly recently. I also heard that it has issues with fan noise.

What are the scope probes like? Do they seem like decent quality?

Has anybody identified what the buttons on the left side of the screen do?

Dave, I am really excited to see a full review of the DS2072 when you get the opportunity. I am very interested in seeing someone operate the device as I have been informed that Rigol doesn't demo this unit.

Thanks again everyone


Jeff

- I looked in the user manual and it appears that the buttons to the left of the screen are for the
"one key measurement of 24 parameters" ie. quick measurement buttons? Has anybody tested these out? do the "increase productivity"?

Agilent DSO1004A = Rigol DS1064B
Agilent DSO1014A = Rigol DS1104B
Agilent DSO1024A = Rigol DS1204B

..for example. All is done by Rigol including firmware and software, there are only cosmetic changes (splash screen, menu colors). Actually the firmware of Rigol units was a bit ahead in terms of bug fixes and new features. I do agree with others, there is really no reason to spend more money on a Rigol with Agilent logo ;)

DS2072 is really nice and very promising unit, I can only recommend..
Bricked Rigol? This thread might be of any help.

I don't mind the fan... on mine it's quiet.

They feel quite good and work well.

I contacted Rigol North America to see if these was any information on new firmware for the DS2000 series units.  I also brought up the X <-> Y label swap.  To be honest
I likely wouldn't of noticed as it's a feature I would rarely use.  After some time the rep from the Distributor called me trying to set up a conference call between me and the tech
in the US (I'm in Canada) at Rigol.  Unfortunately I'm currently very busy during the day, and didn't get a chance to call my rep back.

I did though receive an email a couple days later in which the tech described the CH1=Y and CH2=X as by design even though it was not 'standard' convention with other manufacturers.
He also indicated that he is not aware of any firmware revisions to the scope as of this moment, but promised to look into it further.  I'm hoping this isn't a glimpse of what there is to come over the horizon, i.e.: difficult to obtain firmware updates.  No offense to Dave, but some of us don't carry the weight to get noticed, scoring none milestone revision or test firmware.

I'd like to keep the scope up to date, especially due to the model being in it's infancy.  There are ALOT of things that could be made better with relation to the UI, and adding software upgradable bandwidth would be awesome.

I'm currently evaluating the OPTIONs (trials) on the device, so would hate to update the firmware and lose the trial counters anyway.  I suspect the procedure described using the SINGLE button doesn't work above, as dave did try it on the video.

So looks like I'm out of luck for now with the firmware.  If anyone hears different, please drop me a line.

I'm not getting my firmware direct from Rigol, nor am I requesting it, or even in contact with them about it.
The firmware I got was asked for and requested by the local Oz rep John South from Emona on his own accord. I didn't know about new firmware or the X-Y bug until John told me.
John said he's getting another new firmware update from Rigol on Monday.

Yes, Rigol really need to fix their attitude toward firmware updates, they are very quickly getting a bad rep for it, which is a shame. No one minds firmware bugs (in fact it's good, it shows the company is actively finding, fixing and improving things), but companies need to have a clear central and public repository for it.

I totally understand the occasional revision being done to fix a very specific problem which is not necessary for the MASS market, but when the device is so young you'd expect a great deal of revisions in the first few months slowly trickling down to none.  That point you figure you have a mature stable product.

I think the same reason they didn't include the Bandwidth upgrades as an option is the same thing that fueling them being tight fisted with the firmware revisions.  They're scared the public will end up hacking the options find an easy 'free' upgrade to the higher bandwidth models.

Hasn't Agilent stopped doing the customer activated bandwidth upgrades?  I thought I heard they were stopping last month and it would require the unit to be returned to Agilent...just rumor... might be totally false. (Referring to the DSOX2k and 3k).

But I do agree they are quickly becoming unpopular in my books... I did have high hopes for them until the DS2000 series didn't have a 4 channel option and no software upgradable bandwidth.

We'll have to see how this plays out over the coming months.

No, that is just from certain bandwidth, e.g. 200MHz to 300MHz/500MHz, or 300/500MHz to 1GHz. They are different physical front end circuits.
Been that way from day one.

But isn't that exactly the problem the rest of us, the unwashed masses without the publicity, have? "We" have no one pro-actively requesting firmware updates for us. No one in the supply chain has an incentive to do that for "us".

Rigol's European office hasn't changed this a bit for customers in Europe. They are effectively hiding and are focusing on managing their warehouse. So it is back to China. It is two problems. Having to deal with Rigol China, and second, what should be a push service (Rigol pushing out new firmwares to their customers) is a pull service (having to beg Rigol for an update). And it is like pulling teeth when you have to deal with Rigol.

Yes, Rigol really need to fix their attitude toward firmware updates, they are very quickly getting a bad rep for it,

"Very quickly getting?" They have that reputation for a long time already. No support and broken promises.

No. John did not solicit the firmware update for me, I did not ask for it at any stage, and he did not "pull strings" or anything of the like because I'm involved.  It had absolutely nothing to do with me or the publicity of the blog.
He either requested it for his own scopes he is selling, or Rigol simply offered it to him because he's an official Rigol dealer, and that's what you'd expect them to do with their dealers. BTW, he was the one that found the X-Y issue and got it fixed.
He simply offered me the firmware he got given because he knew I'd be doing a review soon and it might possibly fix some issues.
And BTW, I did not get the scope from him, I got it direct from Rigol NA (US), who presumably did not care enough to follow up and forward me any new firmware.

So in this case I do not have better access to firmware than anyone else, I got it like everyone else likely would, through their local Rigol dealer.
If I was a regular Emona customer buying the scope from John, he'd give me the latest firmware, because that's what good dealers do.

So those who are complaining they can't get Rigol firmware updates, I suggest you ask your local dealer you bought it from. That's one of the value-added services they usually offer, because in this case Rigol themselves seem pretty piss-poor at it directly.

Hi there,

just a moment ago I've watched the video and was curious to see if my DS4012 has got the same bug related to the zoom when recording waveforms - it has not. Works as it should, i.e., when in STOP mode playing around with activating the zoom and turning the big knob both channels are updated fine.

So, only to confirm, there higher model does not have this bug and it shouldn't be there in the DS2000 series.

Thanks for the video.

Kind regards
Gunb
