content: I decided a week or two ago that I need to replace my old Tek 7854 mainframe boat anchor. I have a budget of ~$1000 and the Rigol scopes definitely appear the best bang for the buck.I am set on getting an MSO because I do mainly digital work and also need to be able to correlate with analog on the same screen. So far I have not found any cheap USB logic analyzers for <$300 that will support external triggering from a scope.I narrowed down my choices to the MSO2072 and MSO1074. My question is: How do the LA sections compare between the two, and what software functionality differences exist?From the info I have been able to find, the MSO1000 does not support analysis of stored data, while the MSO2000 can use analysis tools after capture. Am I also correct in assuming that both will do live deocde, or is decode only on stored data?I appreciate the help in advance and if there are any relevant posts I may have missed please link them. I have been researching non-stop for the past week.

content: Quote from: lapoltba on September 26, 2014, 04:51:48 pmYes, that is somewhat limiting. Though you could use a USB LA in one window, combined with something like Marmad's RUU in another window, for the Rigol analog channels. Both on the same screen (PC-side). Both on the scope screen means an MSO.Something that does PC-side integration more elegantly (fully sync'ed) is one of LeCroy's LogicStudio's, which incorporate analog samples from a select set of DSOs into their logic display. That comes at a price though, because IIRC, that's about a grand for the LogicStudio, plus the cost of a scope.QuoteThis part confuses me. All the logic analyzers can use one channel for a trigger, and can control their acquisition from the scope TrigOut. That includes USBeeSX ($169), Saleae Logic ($149), ZeroPlus LogicCubes ($119), Hantek LA4032L ($199), etc. Could you explain a bit more, to clarify?I'd think issues like real-time vs. post-acquistion display, maximum sampling rate, protocol decoders, etc. would be greater factors. And several USB LA units support far more protocols than the Rigol MSOs do.

Like you said not being in real time and having to deal with delays, sampling rates, and limited voltage levels is more my concern. The Saleae is the only one I have really looked at so far, and unless your signals are +/-5V, you need to level shift. I don't want to have to deal with that. I want plug and play, especially for a device like the Logic Pro @ $400 and $500. If I'm going to pay that much, I can get the MSO1074 over the DSO1074 for only ~$250 more with it all built in. The difference is $400 going to the 2000s.I wasn't sure in the specific differences between the 1000s and 2000s though.

content: Quote from: lapoltba on September 26, 2014, 08:27:37 pmOK, that helps.QuoteI don't blame you. The USBeeSX also falls into that same category (though I picked up a level shifter for $17 that lets me handle RS-232, CAN, etc. without hassles). Oh! And they're not +/-5V. They're 0-5V. No negative voltages allowed.(ADDED: Well, the original ones... as Alan's chart below shows, they've made them tolerant now to negative voltages, though not triggerable on them.)However, both the LogicCube and the Hantek have good front-ends, handling broad bi-polar voltage ranges, with adjustable trigger levels, just like the Rigol MSOs. The LogicCube also supports a very large number of protocols, while the Hantek sucks on that count. With the Rigols, the only protocols you'll ever get are what they start with, and the MSO1000Z doesn't even do CAN. Want I2S? Sorry. Flexray? Nope. USB1, IRDA, JTAG, etc. No, no, no.[I'd give a strong vote to the USBeeSX here, for excellent protocol support that's essentially infinite, because they provide tools to easily (without programming) define your own protocols. I've benefited from that several times. And the Search/Locate capabilities, with markers and notes, are spectacular! However, they do require a front-end module to adapt to bipolar voltages, and are limited to a max 25MSa/s rate. Useless when dealing with fast-SPI, for example, but OK when I was doing only 8-10 MHz there.]QuoteAgreed, if you're only looking at Saleae.QuoteLet's focus on that then. Performance-wise they're almost identical, with both offering the same max sampling rates. The 1000z 'only' has 24M samples (8-bits), vs. 28M for the 2000. Or half those, in 16-bit LA mode. Also, the Trigger Threshold range on the 1000z is slightly smaller, at +/-15V, vs. +/-20V. Not normally a consideration.When capturing frames, in Record/Play/Analysis modes, the MSO2000 drops from 65k to 32k, when the LA channels are enabled. I'm guessing the MSO1000z drops from 60k to 30k also, though the spec sheet on that model doesn't reveal that. Both of them do provide live decode capabilities, but they can be a bit slow to update the screen (due to software decoding).The LA cabling on the MSO2000 is somewhat nicer, with 2 separate header pods that can plug directly into board pins. While the 1000z requires flying leads (which the 2000 also provides), from a single pod, coupled to the scope with a wide chunk of ribbon cable. Of course, since the LA option on the 2000 costs $400, vs. $250 for the 1000z, you'd hope there was a bit more there.In the Features category though, you have things on the 2000 that the 1000z lacks. Like the post-acquisition Analysis mode, which can be very helpful at locating glitches, on either the analog or digital side. NA on the 1000z. Also, the 2000 has a Continuous Record mode, which grabs frames as you probe, and you can go back through to look at them, or run a deviation analysis on them as well.Important for some folks is that the 2000 has accurate (1 usec) time-stamps on segmented captures, while the 1000z has none at all (no RTC date/time clock either, for on-screen captures of when an event happened). Right now, we know for sure that the 2000 can decode frames in segmented captures. The 1000z is supposed to (according to Rigol), but I've never seen anyone here that owns one confirm it. The 2000 also has jog/shuttle knobs for enhanced navigation, that the 1000z lacks. And Marmad here has developed a slick PC-side tool called RUU that already supports the (analog side of) the 2000 directly, though I believe work was progressing on a beta-implementation for the 1000z.More important on the analog side than for a digital guy, but while both have Math capabilities that are quite powerful, the advanced Math on the 2000 lets you set up full user-defined formulas, so you could see things like power analysis more directly. The 1000z only lets you select from built-in functions. And when you do need to check the quality of digital signals like clock pulses in the analog domain, the 200 MHz bandwidth on the 2000 can come in handy. The 2000 also has a 50-ohm Input setting, which the 1000z lacks, though you can do as well with an external 50-ohm BNC adapter (if you happen to have them in your drawer).Lastly, one significant difference about the MSO1000z that's far from obvious is that it's NOT a 4-channel analog + 16-channel digital MSO, as one might assume from the marketing lit. For each Group of 8 digital channels you enable, you lose one analog channel. So it becomes a 2A+16D MSO, just like the MSO2000.That's pretty much all I know, though others that own an MSO2000 may have more to contribute.~~If you were asking for a recommendation though, I'd need to know more about the type of things you use the LA side of things for. Because if you need more protocols, more powerful triggering, or stronger post-acquisition analysis, there are better tools to handle that than even what the MSO2000 provides. The downside of course being that you lose the convenience of always having the two A+D sides in sync, without any extra effort. That's a personal judgement, that will be different for everyone.[One flip side of the convenience angle, is that the Rigols can only decodeup to 2 bussesat one time. The USB-LA modules have no such constraint. E.g., I've used a USBeeSX to watch data flow through a vehicle interface device, from a CAN bus, through a 4-channel SPI bus, on to an RS232 stream to a host PC. With bi-directional comms. While sending data to/from a DataFlash module, also over another 4-channel SPI bus. All synchronized, and easily correlated. With channels left over for me to set flag conditions, using GPIO lines.That's not possible on most MSO's, because they lack either channels or decoders.(ADDED: And I just remembered that when I added the 2nd SPI bus into the mix, I switched to my LogicCube, which has 16-channels, vs. the 8 on the USBeeSX. But I did everything else within the 8-channels on the USBeeSX. That made the triggering on the LogicCube more important, since the SX was essentially unlimited capture depth.)]As I mentioned before, the $119 LogicCube has 16-channels,at up to 400 MHztiming mode.[Sorry, only 100 MHz, in async mode. I was confusing it with the Hantek LA, which does do 400.]It's +/-30V tolerant, but triggers only range up to +/-6V. However, it also supports state-mode, with an external clock input that can sample synchronously with your logic bus (up to 75 MHz). None of the Rigols support that. That can drastically cut down on the oversampling required. It also has so many protocols available I've lost track (over 100?). Though it now comes with the first 52 protocols for free. And can be extended. While the memory depth on it is in the medium range (128k samples), it provides data compression, so that really means 128k transitions. Which on a sparsely populated comms bus could be 100x greater depth (i.e., it essentially does run-length encoding, providing a counter indicating how long a state was maintained, up to 255 clock-cycles). [The $119 model comes with a 32k depth, that's easily modded to enable the full 128k samples.]That also means when it comes time to ship the large acquisition to a PC for analysis, it happens very quickly. Vs. sending 12M data points, 95% of which are identical. Which is what you have to do on the Rigols, as soon as you exceed what can be done with their internal analysis capabilities. (I.e., neither has any post-acquisition Search or locate capability, on a long capture. So if you capture a long burst, it could be fun scrolling through up to 28M of bitstream.)My apologies if this is all just a tangent, and you simply wanted to pick one of the Rigols.

content: Quote from: lapoltba on September 26, 2014, 08:27:37 pmI had an older Rigol with an LA and it doesn't compare at all to either a Saleae or Intronix. Honestly I find decoding even simple protocols on my DS2072 not worth the trouble and I go for the USB LA every time.Saleae are in the middle of releasing some new and interesting products right now if you go to their website - their newest products have both digital and analog capability. They are also making some improvements to their software such as a protocol decoding window and many other new features. Two of them support USB3 for higher bandwidth capability. You can also write your own decoders for it if you are familiar with C++.Intronix is cool too and it gives you access to all channels without degrading sample speed. The software has a real time mode already that they are planning to add to the Saleae, but you can't add any custom decoders for it. It has some unique features that the Saleae doesn't such as a custom threshold voltage, etc.Wait, I found this comparison I wrote up when I was looking at them:

content: Thanks for the chart, Alan!I'm pretty familiar with the older Saleae Logics, that couldn't handle bi-polar signals. It's good to see the newer models have rectified that, and are providing lots of new functionality. But I lost a bit of interest when I saw the price tags, and didn't spend much time researching all their specs, after that.

content: Quote from: alank2 on September 27, 2014, 12:25:54 amWow! That's a pretty strong statement. Thanks for sharing. That really is useful information. And I certainly would not argue with it.Of course, one thing that's required to make that a viable option is to have all your ducks in a row in the analog domain. If that was NOT the case, and all you could see was the digital side, then you could easily wind up spending a lot of time trying to figure out problems in the digital domain, that actually originated on the analog side. (Ask me how I know.Ha ha.)When you're 'just' doing trouble-shooting of an existing system, thismaynot be an issue quite as often (though it certainly can happen!). But when you're doingdevelopmenton an embedded system, it's pretty much critical. It's one of those "don't leave home without it" kind of things. I only needed to experience that once, to learn my lesson.

But I have to admit that I spend way more time fussing around with the buttons and tweaking the parameters before it will decode, and even then if some part of it goes off the left side of the screen, it may or may not decode properly or have trouble. The USB LA's just work and work so easily, as much as they lack the appeal of the scope, they just do the job so darn easily!

content: Alan, that chart is great. I will definitely keep that one for reference while I continue to look around. Where did you find the specs for the new Logic Pro? Their website is fairly terrible and I can't find anywhere on it a simple PDF of specifications for any of their products. If the new one does indeed support +/-10v then that *may* be doable as a simple resistor may work instead of a full blown level shift for some things. Differential stuff like RS422/485 will still require extra silicon.Mark thank you very much for the very detailed info and insight. It was not at all a tangent, everything was on point. I had already found some of what you mentioned but it is nice to see it all in one place."However, both the LogicCube and the Hantek have good front-ends, handling broad bi-polar voltage ranges, with adjustable trigger levels, just like the Rigol MSOs.

USB1, IRDA, JTAG, etc. No."(sorry the quote format in this forum is super confusing. Actually, everything on this forum is totally different than any other forum i've been on. I'll figure it out eventually.)I will definitely have to look closer at the USB devices you mentioned. I definitely like the Saleae GUI. It is very slick and looks extremely user friendly. The cost, like you, is what turned me away. I do appreciate that it supports many protocols, and I like the fact that they are actively developing/improving the software. I dug a little deeper myself trying to compare, and it is pretty apparent that decoding is better supported on the MSO0200. Below is direct snip from the User's guide. I completely understand what you are saying, but I think RS232, I2C, and SPI cover 99% of what I would need. The only thing I didn't specifically see mentioned is RS485/422, which I do need on occasion. Of course were are talking about buying the "base model" and "upgrading" it here...."Chapter 8 Protocol DecodingProtocol analysis can be used by users to discover errors, debug hardware and accelerate development easily, so as to guarantee quick and high-quality accomplishment of projects. Protocol decoding is the basis of protocol analysis. Only protocol analyses with correct protocol decoding are acceptable and only correct protocol decoding can provide more error information. MSO2000A/DS2000A provides two buses to make common protocol decoding (including Parallel (standard), RS232 (option), I2C (option), SPI (option) and CAN (option)) of the analog channels (CH1 or CH2) and digital channels (D0-D15). As the decoding functions and setting methods of the two buses are the same, this chapter only takes Decode1 for illustration."I am by no means set on having a Rigol MSO, but it seems like that would be the logical starting point. I'm not doing RF stuff, and nothing that high speed. I value the sample rate rather than 2 extra channels. Like someone else said in another thread I read, with most hobby projects there really aren't many analog signals I need to snoop. A lot is going to be digital and I can use the MSO side for that, reserving the analog for its intended purpose.I'm a tinkerer and I would like to start doing projects at home more. I have a bunch of Arduino and Quadcopter hardware that has been sitting in boxes begging to be used as well as a bin full of components. I've also got a CNC milling machine that I need a scope for to troubleshoot some driver issues. It was supposed to be a PCB mill so I could make my own boards without having to etch. I also do industrial automation (PLC programming and custom built automated machines) with some timing critical machinery at work, and an MSO would be infinitely useful to diagnose some recent problems I have been dealing with.My main concern is usability really. It seems that the mso1000, while it has some decode function, isn't that powerful. It would be more useful for looking at timing and correlating with analog signals only. The MSO2000 though, has more powerful analysis functions, along with a higher sample rate and (maybe?) a more powerful UI with the multifunction knob. It really wouldn't kill me to buy the Saleae or another USB device down the road if the Rigol becomes too cumbersome to use for some reason.

content: Quote from: lapoltba on September 27, 2014, 01:34:08 amAll the specs are on the main page if you scroll down. You might have to click "more" to open up some of them to more detail.Quote from: lapoltba on September 27, 2014, 01:34:08 amThe PRO ones (USB3, higher bandwidth) can read and show an analog signal between -10V and +10V. I think they are tolerant of -25V to +25V for a long period of time on top of that. I remember them specifically saying you could do RS422/485 directly, but you might have to look around on their site to find this. I could be wrong, but I don't think so.Quote from: lapoltba on September 27, 2014, 01:34:08 amTo be honest, they hadn't updated the software for awhile, that was a critique of them that was fair in the past. That has certainly changed in the past 6 months with the new models they are rolling out. I have to tell you though that Saleae is the type of company I love dealing with. When you email them, the main technical developer is usually the one who responds and they have been awesome with me. I am cheap and I expect a lot from a company in terms of taking care of their customer and Saleae excelled in the customer service department. I made a mistake at first by buying a clone from iteadstudio and that was foolish. It didn't work well and was terrible. Then I finally bit the bullet and bought a Logic 16 and the difference was night and day. While I wish their prices were lower, I was foolish to let the price hold me back from what is a great tool.Between the DS1000 series and DS2000 series, I do think the DS2000 series is of higher quality and build. With that said, I just ordered a DS1054Z because it is just too good a deal for a 4 channel scope at $375.Good luck!!Alan

content: Quote from: lapoltba on September 27, 2014, 01:34:08 amThat's not a bad plan at all. You can start out a project with the MSO2000, and once you've verified that there are no analog issues, if you ever find that dealing with huge chunks of data stream with the internal protocol decoders becomes cumbersome or limiting, you can switch to a Saleae, etc.If that's an option for you, I don't think you'd regret going for the MSO2000. Unlike Alan, who rarely works in both domains at once. Who'd likely be unhappy to have "wasted" $400 on an LA version of his DS2000.He had better things to do with that money. Of course, if he was doing much with SPI, the 2-channels on his DS2000 would become a major PITA pretty quickly (too few channels). A problem you won't have with the MSO2000.

content: Quote from: Mark_O on September 27, 2014, 02:02:26 amThat is true. If I need to work in both domains I'd fire up the scope and plug in the USB LA! In fairness to Rigol modern MSO's, my experience was with an old model, a DS1022CD. It did have logic channels, but no decoding at all. If a Rigol MSO is as difficult to get working as my DS serial decoder though, I'm not sure I'd use it if I had it.

I give them top marks.While Saleae's prices may seem to be a bit on the high side (to me, anyway), all you have to do is look at some of the competing products (like the $990 LogicStudio USB module from LeCroy, for example; or even some of the higher end stuff from USBee), to put that in perspective. In that context, they're more than reasonably priced.For a long time, their software was way behind what USBee had to offer (IMO!). That's starting to change now, and things are looking up.

content: Thank you Alan and Mark both very much for the detailed information you provided. It seems that a MSO2072 is in my future. The MSO1074 would probably work for what I need, but I think the extras in the MSO2000 are going to be nice to have. Analysis of stored waveforms and the navi-knob thing are probably the biggest advantages.Now that I see these can be "upgraded" by USB it is a heck of a value. The work done to make that possible is way beyond my abilities. I am certainly one of those people that can never leave anything I own alone, but my mods usually involve more mechanical things.

content: New MSO2072 arrives yesterday to me.I wanted to upgrade my DS2072 to this MSO model.Also I have saleae logic 8 and have played with it a little, so I can compare MSO model with this combination (DS + usb analyzer)The main difference between usb logic analyzer and MSO2072 is that usb LA is essentialy an offline analyzer, it can't provide you realtime picture of what's happening now on bus. MSO shows you logic chanels in realtime, trying to show intensity graded transitions (vertical transition lines are brighter if it happens more often in this place) just like analog channels.Saleae has more protocol decoders, very handy mouse scroll and zoom interaction, but slower update rate, 24Ms/s maximum on fast computer, while MSO2072 have 1Gs/s maximum LA speed (when 8 channels are on, and 500Ms/s with 16chanels).If someone has questions about MSO2072, feel free to ask me, there's few information about it on this forum.

content: I've payed a bit with edge triggering on analog an digital chanels on mso2072.First issue found -Analog chanel and digital D0 - both are connected to the same signal (1KHz square with low rise time).When triggered on analog chanel, digital data appears 2-3ns ahead (first picture)When triggered on digital chanel, negative delay on digital data disappears (second picture).Also I'm impressed with very low jitter (< 1ns) when triggering on digital data. So I can easily use any of 16 digital chanels as an additional external trigger input.

content: Thanks for the input again.The triggering difference between analog/digital is interesting, but not completely unexpected. I believe using a trigger hold off may fix the issue? There is a video of someone on youtube showing essentially the same thing.A real time mode in the Saleae using trigger out from the scope would be really nice. I like the software interface, but the lack of real time and no clear timeline for implementation makes me want to hold off on it for now.
