--ARE YOU HAPPY WITH RIGOL PRODUCTS?--

[Gilbert]

Dear friends,

I see Dave testing a new Rigol Oscilloscope model that looks just fantastic also with its price, while unexpected problems are seen with a power supply he has reported. These equipment look just fine, but how about in general, the quality, performance, bugs, and the feel of them. Sure a trade-off in quality is normal but to what extent is this trade-off. There is a nice promotion here with an oscilloscope, dmm and a function generator, DS1052E - DG1022 - DM3058 (all around $1150), I could not decide to get one set or not. I recently ordered an Hp TBS1052B entry level oscilloscope, waiting for it.

Thanks in advance for your valuable comments,
Regards from Istanbul, Gilbert.

All Rigol devices are more or less bug ridden, firmware support is terrible, customer support is usually terrible, but largely depends on whether you have luck to find someone who has any kind of clue.
I didn't have that luck when I requested a firmware update for my DG2021A function generator which wouldn't work as NI-VISA device over USB interface. Customer support told me that there was no firmware update and that the device wouldn't even allow an update. Which both was wrong. Only by chance I found another user who was given a new firmware by a more competent support person.
Also seeing that Rigol messed up the PLL in the DS1000Z series and the power supplies had/have a couple or more or less serious issues as well makes you wonder how professional their developer really are.
And yeah, the typical Rigol device is usually also much too loud and you need to perform a fan modification to make the noise bearable.

All in all, if you know the issues and can't spend much money, the value for the money is still pretty good.
For professional use, I'd never consider any kind of Rigol product with their current level of quality and customer support.

I'm happy with my Rigol DS1074Z DSO considering what I paid for it and what I got back. I think this is the same for many owners; partly due to the 100MHz hack or the software options unlock on other models. Thereby, conclude why Rigol is so popular in the maker/tinkerer community.

If any serious money is involved for pro use (like >1K euro) I would look at Agilent/Keysight or Tektronix first.
E.g. we have a Rigol DS815A at work. It makes a horrible beep from the internal PSU at likely >8kHz or so. It works fine though.

Personally I have not encountered many firmware bugs, atleast to show stopper extent.
The styling scheme of Rigol is questionable to say the least, but I'm fine with it.
The feel of rotary knobs on my unit is not that great, but I think it will last if you treat your equipment well.
Fan noise is OK-ish for me, but this is purely opinion.


Remember that the DS1052E is not comparable with the DS1000Z by a long shot. The memory extension, trigger options, intensity graded waveforms are incredibly useful. Comparing 1052E to TBS1052B it's probably equal games, although I haven't looked in depth.
I'm not sure about the value of the DM3058 really. I have read there is very hard competition in the price bracket, and the Rigol is not as outstanding as in other test gear.
Not sure about DG1022 at all.

[jaromir]

I'm using DS1052E at work for a 6 years or so. Generally I'm satisfied with it, especially for the price. I bought one to my home laboratory too, year ago.
I consider buying DS10xxZ - it has better specs, as hans suggested.

[Armxnian]

As you've already mentioned, you can build an entire lab consisting of Rigol products that cost as much as a single piece of test equipment from the bigger brands. They are built better than the other Chinese stuff but are still plauged with fairly crap software like the others. If you are a beginner looking to become a professional I would recommend buying entry level Rigol compared to spending money on quality gear. By the time you learn how to use all the features and advance your knowledge something new will come out. Plus with increased knowledge you will better know what you require. As for hobbyists, most don't want to spend many thousands of dollars. Rigol is fine for that purpose. If you outgrow the gear and still have interest in electronics then you can buy better gear.

[Lightages]

I have only two Rigol products, the DS1052E and the DS1054Z. Both have been useful and without the bugs affecting me very much but I don't use all their features extensively. The quality is OK but I am not sure I would have purchased them without the possibility of the freely available upgrades. Without that, I would be looking at Siglent right now. They are fairly responsive and seem to be more customer oriented than Rigol.

I would not get the DS1052E now unless it was for more like $150 in used good condition. It is less than half the scope that the DS1054Z is. Just because it is bundled with those other instruments does not make it a good buy. I would also argue that the multimeter is a OK, but if you need it to be calibrated and adjusted then you need to send it to Rigol as it appears they have not released the procedure to any third party. I find it a bit suspicious that they haven't released any of these procedures, that I am aware of.

Perhaps it is better to think of Rigol as being a basically something you buy and use for a few years and then buy again. Don't count on all bugs being fixed, and don't count on being able to repair or calibrate.

Perhaps I am wrong about their procedures not being available, but it was asked of them by someone here and they were told to send their instrument back to Rigol for adjustment.

[mazurov]

When I was shopping for a DSO I picked Hantek, for the reasons already given by other members. Rigol is OK but so are many other Chinese instruments; you really don't pick it by a brand name or advertised features or even price. Instead, you look at issues ppl are having with the gizmo and ways to overcome them. Take a look at @tinhead 's Hantek thread, for one such example.

I also tend to favor instruments for which the majority of the content doesn't come from the manufacturer.  This approach works very well for me with old gear; seems to work even better for Chinese products - I'm yet to buy one that won't perform as expected.

[Muxr]

Capabilities for the price are off the chart. Especially when you consider the relatively easy unlock to the top tier of the line.

I have a DS2072A. It's a nice scope, with the unlock it's 300Mhz 2Gs/s, with 56M of sample memory and quite a bit of features. You just can't get that anywhere else for $800. (unless perhaps getting 2nd hand). Agilent's comparable scope at 200Mhz and 2Gs/s the DSOX2022A is $2250, Tektronix's TDS3032C is $8065.

Granted Rigol's waveforms per second are pretty weak, but that's a secondary stat to analog and digital bandwidth for most. So all in all I am happy with the bargain.

Out of the box I wasn't happy, because the firmware it came with was locking up all the time. Current version I am on, seems to work fine.

Generally speaking. The controls aren't the best but they are manageable. The UI can feel sluggish at times as well. The build quality is adequate. But bang per buck is there and that holds true today as it did when I was shopping for a scope.

Would I buy it all over again if I was in the same position? Most likely. I would perhaps go for an MSO in the future. I think the convenience is worth the premium.

I have 2 other scopes. A Hameg HM605 and an HP 54610B, and they are both more fun to use than the Rigol. In fact I kind of actually admire the job HP did on theirs (Hameg is full Analog and it's great). The HP is running the same factory firmware with zero bugs. The firmware is just so well written, it even has an easter egg Tetris clone game. It has much less features than the Rigol so perhaps not a fair comparison, but the UI just feels so much more intuitive and responsive, even with way less buttons. Often times on the Rigol it feels like a certain setting I am looking to disable is hidden behind too many menus. It just doesn't feel logically laid out.

A simple fact that the smallest encoder knob on the scope (the intensity knob) is the one you use the most, while the biggest one the one called the navigation knob is rarely ever used for anything speaks volumes of Rigol's knowledge of user interface.

Although I think the UI is a common problem with newer scopes. Since now days the scopes are designed by software engineers (I am one of them). They often times don't really understand the electronic engineer's workflow. This is why old analog scopes feel so much better to use.

It is sad because I think the ergonomics are really an important part of a scope. When you're using a scope your mind is usually occupied with debugging a problem. And the last thing you want is to be distracted by quirkiness of the tool you're using.

[Zero999]

I've recently got the DS1054Z for just £248 (352 Euro, $377)  including shipping and taxes.

I've unlocked all the features and haven't had any issues with it yet. The controls could be better but it's overall good value.

[miguelvp]

DS2072 here and still happy with it, haven't outgrow it yet.

I do have 3 analog ones, all Teks (5110, 7603 & 7613) and I do use the 76xx every now and then because I have a ton of plug-ins. But the Rigol is my main scope.

That's the only Rigol product I own and had it for a year and a half, I couldn't be happier with it.

[tautech]

I have only two Rigol products, the DS1052E and the DS1054Z. Both have been useful and without the bugs affecting me very much but I don't use all their features extensively. The quality is OK but I am not sure I would have purchased them without the possibility of the freely available upgrades. Without that, I would be looking at Siglent right now. They are fairly responsive and seem to be more customer oriented than Rigol.

Yep, one wonders about build quality, support and their bugware, but for me it's specs.
I often ask myself who would buy a scope with only 300V inputs and 250ms/s in this day and age. 
How can one also use a scope with a common vertical attenuator for up to 4 channels, it would drive me nuts, real nuts.

So you think I'm taking the opportunity to chuck some mud, not at all, just sharing some valid thoughts.

Some years ago when looking very carefully at DSO's to import, the above spec criteria were non_negotiable for my needs. Essentially there where no more brands available then as is now but specs are vastly different across brands.

Now I'm a Siglent distributor little has changed, specs still dictate my selections and patience with Siglent to produce more competitive products. I can't share much, but I can say their new DSO will challenge the 1054 on several fronts.
 

[Jeroen3]

You buy a Rigol if the budget is the limiting factor. Otherwise you buy a fancy tektronix or agilent.
For the same price as a Rigol, you get a rubbish piece of tektronix. So it's either rubbish or feature packed with a few (complicated) bugs.

To be honest, the bugs found in the rigol ds1000z are not "simple" ones. You have to match a series of specific settings to reproduce them.
With a TBS1152b, the thing just crashes if you insert a USB drive. Or when you press two buttons fast enough.

So overall, yes happy. I even take it to work sometimes because even the more expensive tektronix devices lack the trigger features available in rigol.

[Zero999]

Oh, I forgot to raise my one major gripe with the DS1054Z: the colour scheme. For some silly reason they chose a similar colour blue for the math trace as that used for channel 4. They should've used something completely different such as green, red, orange etc. It has a 16-bit colour display for goodness sake, they're hardly short of choice!

[Howardlong]

From Rigol I have both MSO1074Z-S and DS1074Z-S oscilloscopes, a DP832 power supply and a DSA815-TG spec an.

There is no doubt that had it not been for the potential post-purchase optimisation at least three of those four purchases would never have been made.

I do also have a reasonable selection of other oscilloscopes up to 20GHz sampling scopes, but my favourite go to scope is a 15yo HP 54642D 2+16Ch 500MHz 2GSa/s due to its almost instant on and awesomely easy to use UI. The MSO1074Z-S is my field scope and the DS1074Z-S is lent out.

On the PSU, I have a couple of other simple cheap single channel units that I've had for some years that I still use at least as much as the DP832. The DP832 is good for slightly more esoteric features like OCP and paired supplies, as well as having single digit mA and mV plus W readout.

The Rigol spec an does get used quite a lot more than the other two spec ans I have as it has the best feature set, although the worst frequency range, I have an old HP YIG boat anchor that goes up to 22GHz.

Regarding the OP's Tek TBS1052B, I still have my TDS2024B 4ch 200MHz 2GSa/s scope that has done me well for many years, but there's no doubt the Rigol beats the pants off it in every way except bandwidth and channel specific controls. The Tek's been in its bag almost permanently for a year or so, but it has a good deal of sentimental value to me, it's paid for itself many many times over during the past decade or so I've had it, several very successful products were developed with it.

I bought the Tek because, well, it was Tektronix, and a decade ago while it might not have been the best value for money the far eastern alternatives had little track record or reliable reviews. It was about US$2,500 too... ouch, I remember that hurting.

Rigol gets its fair share of criticism in the bug department, much of it warranted, but bang for buck, even with those oft reported bugs, it really can't be beat. If you think Rigol is bad you just need to look at some of the other brands from the same neck of the woods. Also keep in mind that Rigol is extremely popular, and with that popularity it means the chances of finding a bug and publicising it is far greater. Some of the apparently show stopper bugs have taken months if not years to come to light and be generally acknowledged. While by no means perfect, some of them are extreme or rare use cases: after all, they have taken a long time to come to light, so they can't be that frequently observed. Again, I am not excusing it, I'm just putting it into perspective.

[alsetalokin4017]

I love my DS1054Z, I _actually use_ it every day. But come ON, give me a break....

[LektroiD]

I have the DS1054z... I see the main gripes on Rigol products tend to be the lack of firmware support and the colour scheme (I have to agree on both counts). But you get a hell of a lot of scope for very little money!

It wouldn't surprise me if the DS1054z is the biggest selling scope of all time.

[Muxr]

It wouldn't surprise me if the DS1054z is the biggest selling scope of all time.

That would be difficult with the rate of change today vs. back when Tek made 465s, 465s sold for a long time, also Radio TV repair business is mostly dead now days, and those scopes were sold to everyone, from techs to governments. But there are way more people that can afford the DS1054z and the user base of scopes has probably grown. So I think you might be right.

[xrunner]

Bought a DM3058E a year ago and have no complaints at all. I installed one firmware upgrade in that time.

I ordered a DG1022 last week and should be here this Wed., I'll let you know about that one in due course. 

[EEVblog]

Rigol's firmware support leaves a lot to be desired, but they do listen and do fix things, both hardware and software.
Bottom line is they are compelling bang-per-buck, and if it was my own money setting up a lab, I'd almost certainly buy a lot of Rigol gear.

[coppice]

Vendors on Taobao were saying the DS1000Z series had sold 20k units a few weeks ago. Now they say 30k. That's well below some famous historic scopes, but they achieved their sales over many years. If the DS1000Z series stays competitive for a while it may well become the biggest seller.

[Circlotron]

I've had my DS2072 with 56M memory for almost 2 years now.  The deep memory with segmented facility means I can have an engine on a dynamometer, do a power run and then scroll through every single one of several thousand ignition events one at a time. I love it! We had a new project that was misbehaving and we were getting somewhat into deep doggy-do. Bought the scope and sorted it out in about a week. Scope paid for itself many times over in that one job.

The bit where you have to make a menu selection then push the button and it jumps to the wrong selection as the button is pushed is a bit annoying. Also sometimes the frequency counter displays <15Hz until you wind the trigger level up and down a bit. 800x480 screen resolution is better than some similar scopes. The math equation writer is great - no getting stuck with only several presets. I often use int(ch1*ch2) for measuring ignition spark energy in my test jig. A small thing perhaps, but majorly useful for me. I'd buy another one in a heartbeat.

*** It is my first and only DSO so maybe my opinion is somewhat subjective.

[bitwelder]

They should've used something completely different such as green, red, orange etc. It has a 16-bit colour display for goodness sake, they're hardly short of choice!

Even before looking at the math trace, why using two types of blue for channel 2 and 4 ?

[0xdeadbeef]

Rigol's firmware support leaves a lot to be desired, but they do listen and do fix things, both hardware and software.

They might listen to you when there's enough attention, but that's not really the idea of good customer support.
A normal customer gets confronted with some support guy/gal with a fake English first name who doesn't even know the products and fobs you off with some empty phrases and you know your question/report will never reach the engineering department.
The most annoying thing about Rigol and the likes is that they tend to release a new product before fixing the old one. E.g. the DS2000 was already replaced by the DS2000A.
Admittedly, that's the same for other Chinese vendors. But they usually have a proper firmware download possibility at least. With Rigol, you need to beg to get an update and if your support person is stubborn or stupid, you get an old version or are told that there are no updates.

[Jeroen3]

I'd expect things to change if they establish a large customer base on the new 1000Z model.

[rdl]

Rigol is okay I guess. I've had a 1052E for a few years now. It works fine and I requested the newest firmware (for the first time) about 6 months ago. They e-mailed it to me in less than 12 hours and it installed with no problems. However, I really dislike the styling of their latest stuff. I consider it bad enough to avoid them in the future.

I'd probably already have a few of the DP832 power supplies if it wasn't for the stupid looking telephone dial buttons, and the front panel of the DS1054Z is an aesthetic mess. I realize a lot of people (maybe most) would disagree with me about the importance of the appearance of the product, but I prefer something I use all the time to at least not annoy me because of how bad it looks.

[xrunner]

Well, I got the DG1022 this afternoon, and I'm very pleased with it. Been checking it out for a while and it sure beats what I had (a GW Instek GFG8216A). Everything seems to work as advertised - sweep, arb, all waveforms ... ah what a luxury compared to what I had! Interesting thing is it has a screen saver option in the utility menu - my DM3058E doesn't, not sure why they don't have one in the DMM since it has the same type of screen.

In any case it's plenty good for my hobby needs. 

[brumbarchris]

why using two types of blue for channel 2 and 4 ?

one is called cyan, one is called navy blue, if one is to be more suck arse precise. go to painting artists or look at the pantone chart and see if you can memorize all the name of blues... muggle even say orange and red is in the same line of color...

and err, the math trace is more like a purple, not blue... there are new fancy names today i forgot what, its the dress color, but for me its simply purple, just less saturated, less brightness purple

Lots of engineers mourn the loss of colour coded resistors, and other colour coding around the electronics world. Few women have colour blindness issues. About 10% of men do. In most countries women engineers are rare, so around 10% of engineers are very happy to see colour coding schemes dropped.

[rstofer]

I have only had my DS1054Z for a couple of weeks and I have done the usual stuff like look at counter outputs from an FPGA and decoding of a UART stream.  Nothing that challenges the scope.  Considering what I do in the sandbox, I may never challenge the scope.

If the scope is annoying, get rid of it.  If the UI is slow, get something else.  Life is too short to work with tools you don't like!

I didn't buy my scope to win a beauty contest and the UI works about as fast as I can manipulate the knobs so I think I'll hold on to it for a while.

I just did a sample of Math A+B using 2 bits of a binary counter on Ch1 and Ch2.  The sum of A+B is exactly what I would expect and the trace aligns perfectly.

A couple of days ago, someone said that none of the trigger modes other than Edge worked on the DS1054Z.  Specifically, they said I couldn't trigger on a character in a UART string.  Well, they had me going!  So I rigged up an Arduino to send character strings and, voila', the trigger is perfect.

Be somewhat doubting about what you read on the Rigol bashing threads.  Much of the information is wrong!

I find the cyan and blue traces easy to tell apart.

I find purple and blue are more difficult to distinguish on the Rigol's display, even though it's easy on screen shots because a computer monitor has better colour than the Rigol's display.

why? its the naked truth that i dont get why most modern people try to deny to this basic instinct, unless maybe they've been crippled in someway i dont know. ask yourself why fashion and cosmetic industries was, is and will always a boom. and plastic surgery has become boom boom, its just overly done and overly... i agree its rude to say it out loud in cross or mixed gender gathering, but i guess here is more men. i guess talking man to man is ok, but man to woman is certainly not.

interesting to know. so maybe you will have a difficulty looking at channel 3 of ds1000z? maybe not entirely blind since its not a sharp red (pink). in the link i attached, i read color blind people developed ability to distinguish colors differently from normal people, maybe they see red and green as the same color, but different intensity, so at least maybe they know.

As with all things, there are degrees of color-blindness.  I don't see ANY of the letters or numbers in the 'dot' test.  I fail completely!  Yet I can deal with color coded parts.  I tried one of the online tests yesterday and didn't do too bad but it all about matching colors.

I see 'red' as what I have been told 'red' looks like.  Same with all the other colors.

Besides, we know that the red traffic light is on top and the green on the bottom.  Except for that one in Syracuse
http://gizmodo.com/the-story-behind-syracuses-upside-down-traffic-light-1545301615

None of the colors on the 1054Z are a problem for me.

[arobincaron]

I am satisfied with what I've seen and experienced with the DS1054Z I've used.  As complex computer based devices DSO are likely to have bugs and issues. It seems best to evaluate for yourself whether this a problem for you.

As far as quality: generally you get what you pay for.  With regards to Rigol I seems to me that you get above average value. That's good enough for me.

[bitseeker]

I only own one Rigol device (DS1054Z) and it's still under warranty. So, for the short time I've had it, it's been fine and does what I need it to. Thus far, I haven't run into its known bugs during normal use. So, I'm a happy camper for the time being.

[jitter]

Rigol DS1074-S, bought just over a year ago.
Running version 00.04.03.SP2, board version 4.1.1.

I'm quite happy with it. No crashes or firmware bugs that bother me (yes, I know there are a few, if you look hard enough).
What I dislike is the fan noise and some printing on the front, whoever thought that white letters in a light gray box are easy to read? Oh, and the probes aren't very easy to take off the BNCs.

But these little things pale in comparison to the value for money.

The scope I use at work daily is an Agilent DSO-3054A. Of course it's better, but even if I had the money to spend, I could hardly justify the € 9,000 or so that it costs more than my little Rigol...

[Monkeh]

Oh, and the probes aren't very easy to take off the BNCs.

The supplied probes generally suck. Crap hook, dodgy switch, awkward BNCs, stiff ground clip.. But probes are just probes, they are, for this range of scope, cheap consumables.

[hibone]

Depending on the angle one is looking from everything has "defects", thus one should take them into account when choosing. What about 4k$ with a crappy "UI"? What if they are Tektronix or Agilent?

I have a DS2072A-S, fully unlocked too, and I am happy with it.
It has its flaws, of course, but that's it.

When you need a feature that is locked away, and you cannot afford to pay for it just to use it once, doesn't that look like a bug?

[jitter]

Depending on the angle one is looking from everything has "defects", thus one should take them into account when choosing. What about 4k$ with a crappy "UI"? What if they are Tektronix or Agilent?

We have quite a few Tek scopes at work and for some reason the choice had always gone to Tek, almost by default. Same with Weller solder stations.
Along comes someone who says "we're going to have some demos over from several other manufacturers and try them out first before whe choose". If you're a company, there are no problems to arrange that, the salespersons will flock to your door to lend you stuff.

In the end we decided on a switch to Agilent scopes. They felt so much more ahead of the competition at the time that the decision was easy. And if I see how sluggish that modern Tek in Dave's vids still is I can't help but think they haven't managed to catch up. Later we actually bought some Keysight scopes untried because we already knew what to expect. Never looked back to Tek and another department ditched their LeCroys and bought Agilent/Keysight too...

For solder stations we went to what seemed to be the new kid on the block at the time: JBC. Again, we never looked back.

It all comes down to choice and if I had to buy a scope for home use again, I would definitely consider the DS1000Z series again. But maybe now there's also competition in the same price bracket that's worth considering.

There's definitely more competition for the DS1000Z series nowadays. Hence, it's good to re-evaluate your choice of supplier from time to time, as you had experienced with Tek vs. Agilent.

I've had my DSA-815TG for about 2 years and am absolutely thrilled with it.  As an educational tool for someone who is learning RF electronics, it has been my single best investments.  I try to absorb as much info as possible about spectrum analyzers & related test gear, so I've learned much about its limitations compared to higher end gear (with enormous thanks to W2AEW, Shahriar at TheSignalPath and others).  But I am solidly convinced that the bang for the buck is unsurpassed.  The performance limits so far have been inconsequential to me.

I've also had a DS2072-AS for about a year.  Originally, I was going to get a Keysight DSOX2014A, but changed my mind in protest over the shitty way Keysight treated me in an unrelated deal.  I stuck $1,000 back in my pocket and set my sights lower.  I run into limitations with the Rigol a lot more frequently than I would with the other, but I'm still very happy with the price/performance ratio.

That $1000 saved is like your own extended warranty.

I'm not really convinced about Rigol and their scopes. We have one in our club and I find it not very intuitive to use (used many years HAMEG and Tektronix).

I'll wait until I can afford a Rohde & Schwarz 1232 (which I will hopefully purchase this year).

I've had my DS2072 for almost 3 years now. Fully unlocked, not sure what firmware.
Just the other day I noticed something. Had it set to RS232 decode and was watching several bytes at a time. Set it to normal trigger mode and it was as steady as a rock. Then turned on that thing that shows the byte values across the screen right next to the actual waveform, and the triggering was now lousy! Really hard to get it to lock, but if I turned off the byte value display it was back to good again. Hmmm....

I love my Rigol DS1054Z!

It makes me laugh every single day.       

[alsetalokin4017]

I have only had my DS1054Z for a couple of weeks and I have done the usual stuff like look at counter outputs from an FPGA and decoding of a UART stream.  Nothing that challenges the scope.  Considering what I do in the sandbox, I may never challenge the scope.

If the scope is annoying, get rid of it.  If the UI is slow, get something else.  Life is too short to work with tools you don't like!

I didn't buy my scope to win a beauty contest and the UI works about as fast as I can manipulate the knobs so I think I'll hold on to it for a while.

I just did a sample of Math A+B using 2 bits of a binary counter on Ch1 and Ch2.  The sum of A+B is exactly what I would expect and the trace aligns perfectly.

Did you try that test at 500 ns/div, Average acquire mode, and with a third channel turned on?

A couple of days ago, someone said that none of the trigger modes other than Edge worked on the DS1054Z.  Specifically, they said I couldn't trigger on a character in a UART string.  Well, they had me going!  So I rigged up an Arduino to send character strings and, voila', the trigger is perfect.

Be somewhat doubting about what you read on the Rigol bashing threads.  Much of the information is wrong!

Perhaps _some_ of the information is wrong, like the statement about the triggering problem (which did not come from me; I've even demonstrated several very useful trigger modes other than Edge on my YT channel) ... and/or perhaps you are just not setting your scope appropriately in your sandbox to see the problems.

Take a look at the two scopeshots I've posted up above. Is this some "obscure" setting or usage of the scope? How many people will simply accept what the hardware frequency counter says without checking it against the actual graticule and sec/div settings? Why does the scope trigger on a falling edge when it's supposed to be triggering on a rising edge? Why does _only_ changing the trigger level between two very reasonable settings on a perfectly ordinary signal cause this set of errors?   

Trust... but verify.

Trust... but verify.

In my case, with the FPGA outputs, I already knew the frequency and the DS1054Z counter was exactly correct.  But, you're right, it's good to verify.

I had two goals for the scope:  Check SPI with 4 channels, triggering on CS' and looking at acceleration, velocity and displacement simultaneously on my analog computer.  The Digilent Analog Discovery does a terrific job for both of these uses.

I haven't modeled the damped harmonic system but I did just model a circle and displayed it in the X-Y mode.  First, it works!  And Measure-All gets what is an entirely reasonable answer for Vp-p and so on.  There are a couple of things I need to play with:  First, I don't seem to be able to increase the persistence in X-Y mode and to accommodate this, I need to speed up time on the computer.  My base time is 1 second and 10x is 0.1 second.  Next evolution, I will incorporate 100x.  Good stuff to know!  Second, the X-Y display is under the YT display and it's in a little box.  I need to study up on that.  But, heck, X-Y is simply a diversion.  Time to read the book, I suppose!  But first the adventures...

There is indeed some variation in triggering, even on edge, as a function of the trigger level.  Nothing I haven't been able to work around (change the level to get what I want) but, yes, it is apparent.  I particularly noticed it when decoding RS232.  Not just triggering RS232, actually decoding it.  Unless the phase of the moon is just right, there is every possibility that the decode is wrong.  Twist the trigger level knob and things clear right up.  I'm not sure I understand all I know about this issue.

Coming from an analog scope, the part I find the most confusing is the fact that the trigger point is in the middle of the screen by default.  Yes, I know I can move it but, still, I'm used to traces starting over on the left.  It'll take a while.

As it stands today, the scope is doing everything I had hoped for.  I really have no issues.  Even if I had issues, I wouldn't be willing to spend a great deal more money to buy something else.  I read a thread where somebody wants to skip over the Rigol and move to an R&S scope.  It has three times the bandwidth (great!), half the channels (sigh...) and five times the cost!  I'll pass!  This is just a hobby...

There are probably only two people on the planet interested in analog computing but I find it gives me much more insight into the differential equations I was barely able to handle back in college.  Things would have been a lot easier if we had had analog computers in the lab.

While I tried to recreate your error I found that it doesn't trigger at a point at which IMHO it should be perfectly able.
It won't trigger a 2.5 V_pp 1 kHz square with 2.5 V offset until the trigger level reaches 440 mV... 
Edit: the same thing happens if you trigger on the falling edge and move the trigger level above 2.16 V...

It's a little worse than that!  It appears that the minimum value is some percentage of the full waveform.  As the V/div increases, the trigger level increases as well.  When I decreased the V/div, I was able to trigger at 120 mV.

Does it matter?  Not to me!  I'm sure even my Tek 485 requires some voltage above the noise floor.

Here's my criteria:  Is the image what I expect?  Can I trigger on it?  If so, we are GTG!

There's a little button down the bottom which says 'notify'. Yeah, it's so you don't notify all of us.

I have had my DS2072 for a few years now and it has been rock solid for me.

It doesn't really hold a candle to the Agilent that I used in my college days, but for common hobbyist stuff it should be more than sufficient.
Yes, the interface layout is poorly thought out, and the UI lags a little, but I have learned to compensate and don't even really notice these little niggles anymore.
Considering what I paid for the scope and how much an equivalent scope from a more reputable brand costs, I find the drawbacks acceptable.

Besides, that is extra money for more equipment!
