content: Hi, i want to buy a new scope, the one i have right now is a 2ch Hantek, i was looking the models MSO5074 and the new DHO914s, both from rigol, and for me it seems that the only advantages in the DHO914s are the 12bit resolution and the price of course, i need some advices to make my choice, is the 12bit so much better that is worth to give up in other features?

content: QuoteThis question in itself is worth becoming a topic of its own.Currently there is a lot of hype about the 12 bit, especially with cheap scopes.Fungus has already said it, it depends on what you want to measure, where your focus is.To your actual question...I had the MSO5074 over a year in use, also I had a DHO4204 to test here.I assume that the software is the same for all Rigol 12 bit scopes, at least it would be strange if not.Therefore, I dare to say that if you do not need 12 bit (native, because the MSO5074 has 12 bit as Hi-Res mode) and if you do not mind a somewhat dusty UI, the MSO5074 offers div. advantages.Larger screen, larger bandwidth, more memory, max. 8GSa/s, 2-channel AWG, better FFT, etc., etc....The biggest disadvantage is the front end noise of the MSO5074, but that only plays a role if you want to evaluate very small signals.However, I don't think the scope will be really taken care of now that the new 12 bit models are out..

content: Two advantages for the DHO914 that I like are:1. Built in battery support with USB-C power port, making it very portable.2. If you want to do PC logging and maybe FFTs on the PC the 12 bit is going to help.

content: Quote from: franciscoPT on September 10, 2023, 10:15:02 amAny/either model is a concern, when it comes to Rigol and their software "management" process. You, like myself and others, have to / have had to make the decision whether or not to temper that risk against possible rewards, including the price point.Only time will tell and certainly, the new software architecture demonstrated in the DHO series will likely become adopted across all future models (12-bit and otherwise) as the potential for code reuse greatly enhances the economics of future development and of lifecycle maintenance.However, it's by no means certain this means no further firmware releases for the MSO5k series. The latest FW for both the 5k and the DHO1k/4k both date from May this year, so it wasn't "dropped" when the DHO line was first introduced.And, the DHO800/900 whilst interesting, aren't "God scopes" and don't overlap the MSO5k's capabilities. So I think ultimately, it will all depend on sales revenue. Whilst the 5k continues to sell (and by all accounts on other threads, it was doing quite well in the best sellers lists of the likes of Batronix), it will likely continue to receive some development cycles.

content: I'll think that the hobbyists will buy both an MSO5000 for the benchwork an d a relatively tested functionality and a DHO8/900 for its newness,12-bit and portability. Both scopes use the same LA-probe so that investment is shared.

So far we've seen (far too?) much about fan noise and boot time and very little by way of objective review of performance against claimed specification, usability and "completeness". I'll be holding off until at least I've some confidence that it actually works well as an oscilloscope of its specifications, rather than a cute, portable Android-based, Doom platform / hacker fest, which can also be used to display some waveforms if you're into that sort of thing..

IMHO. Maybe the extra memory depth or bandwidth together might justify it but it's already starting to appear as if the 800 is hackable in those regards.YMMV

content: Quote from: franciscoPT on September 10, 2023, 10:15:02 amThe MSO5000 has been out for about 5 years I think. I also believe most if not all the important bugs have been ironed out. While they have released a couple firmware updates earlier this year (including VNC support!), I think that anyone planing a new purchase shouldn't count on MSO5000 firmware updates except to handle any hardware changes (such as the new nand chip they're using in manufacturing now) or maybe to fix bugs - and I wouldn't count on much in the way of bug fixes either.I'm not saying it can't or won't happen, I just think it's something that shouldn't be expected. I'm pretty sure the MSO5000 is about as polished as it's going to get.Personally, if I were looking for a new scope right now, I'd almost certainly go for the DHO914 or DHO914S over the MSO5074 unless I wanted the larger screen, 250MHz/lower sample rate/lower memory depth wouldn't cut it, or I really needed the second AWG. Is there anything else the MSO5000 has over the DHO914 spec wise?(Note: I'd also look at Siglent's offerings in the same price range and maybe hold out to see where the SDS1000X HD lands pricewise in USD)I'd also try to hold out for Black Friday/end of year promo season. I have a feeling there are going to be some good deals again like last year.

content: Quote from: simone.pignatti on September 11, 2023, 03:52:01 pmHi.I have an MSO5074.@simone.pignati offered the possibility of carrying out comparative tests between the MSO5074 and the HDO914S.Originally the DHO914S has BW=125MHz and has an AFG (Arbitrary Function Generator).The MSO5074 originally has BW=70MHz and has 2 Signal Generators, SG1 and SG2.The BW of the two models are different. And the comparison may not be correct in many tests, near and above BW.The DHO914S has 12bits of Vertical Resolution = 2^12 = 4096 steps.And Horizontal Sampling Rate of 1.25MSa/s (for 1 channel connected).The MSO5074 has 8bits of Vertical Resolution = 2^8 = 256 steps.And Horizontal Sampling Rate of 8MSa/s (for 1 channel connected).The DHO914S wins in the Vertical Resolution comparison: 4096/256 = 16x.The MSO5074 wins in the Horizontal Sampling Rate comparison: 8/1.25 = 6.4x.As a first idea, I suggest (Preheating = 30 minutes):1. Simultaneously insert into both Oscilloscopes a Sinusoidal signal, without modulation, of 100mVpp, f=10MHz, with Z=50 Ohm, with a 50 Ohm coaxial cable, RG-58 or RG-316, or other. You can use SG1 of MSO5074.2. Place a “T-BNC” on CH-1 of the MSO5074, continue with another 50 Ohm cable to CH-1 of the DHO914S, place a “T-BNC” and a terminating resistor of R=50 Ohm.3. On the MSO5000 and DHO914S, activate Measurements:Horizontal: FreqVertical: Vpp, VrmsStatistic -> Count = 1004. After 100 counts -> (STOP/RUN) -> Save the IMG on PENDRIVE, on each Oscilloscope.Compare the Avg -> VRMS of the two models, and if interesting, the other Measurements in the Statistic mode.5. Hi Resolution 12 bits on MSO5074:MSO5074 -> Aquire -> Acquisition -> High Res.(Repeat item 4) -> (STOP/RUN) -> Save the IMG on the PENDRIVE, on each Oscilloscope.Compare the Avg -> VRMS of the two models, and if interesting, the other Measurements in the Statistic mode.6. Simultaneously insert into both Oscilloscopes a Sinusoidal signal, without modulation, of 100mVpp, f=50MHz, with Z=50 Ohm, with a 50 Ohm coaxial cable, RG-58 or RG-316, or other. You have to use an external one: RF Generator or Waveform Generator.7. (Repeat items -> 3, 4, 5).8. Compare all the results from (item 4), and give your opinion.Another suggestion:If possible, use a DHO924S with BW=250MHz, and an MSO5074 with expanded BW=350MHz.9. Simultaneously insert into both Oscilloscopes a Sinusoidal signal, without modulation, of 100mVpp, f=200MHz, with Z=50 Ohm, with a 50 Ohm coaxial cable, RG-58 or RG-316, or other. You have to use an external one: RF Generator.10. (Repeat items -> 3, 4, 5).11. Compare all the results from (item 4), and give your opinion.12. Place the IMGs saved on the PENDRIVEs in this topic.13. Comment on the loss of RF signal in the RF cables and connectors used.

content: I have an MSO5104, MSO5074, and a DHO914s. I bought the DHO914s to see how good the 12 bit resolution was, especially for audio FFT. It is a bit better, but the MSO is still far superior from the operator's standpoint. The large screen on the 5000 will spoil you. Also the MSO5000 supports VNC, which allows rapid control from though the net. With the VNC, you can put the display on a giant screen and zoom it to fill the screen. The DHO914s does have better response on a browser connection. The biggest problem with the DHO914s is the necessity of switching channels to control a channel. Many times you might be thinking you are controlling channel 1 when in fact channel 2 was still selected. I do like the VESA mount which allows the dho914s to be mounted on a bracket.

I want to replace an old four-channel agilent with something that has a logic analyzer included, LIN/CAN decoding and an AWG is appreciated to test some analog sensor circuit, but essentially I am going to use it in digital applications. Is the usability of the DHO914s reasonable? I would greatly appreciate personal experience from those who have used both models. Thank you

content: I agree with you, what gives me doubts is that the MSO5000 has already been around for 5 years and I suspect that they will stop supporting it soon. In that sense, the DHO surely has more bugs but it has a more modern design, it will age more slowly. I am very attracted to the 8GSa/s that allows me to detect glitches 3 times faster than those detected by the DHO, half of my use of the oscilloscope is that, detecting glitches (although to be honest they last longer than those detected even by the DHO ). The screen and independent controls per channel for the vertical one are a very strong advantage, but on the other hand those who have the MSO say that the interface is much slower and clunkier than that of the DHO.The possible battery use of the DHO is also a very strong point in its favor since many times I have to monitor CAN lines far from the AC line but with 24 volts easily available. 12 bits don't really interest me, they are not a decisive factor but it scares me a little that everyone says that the analog front end of the MSO is really very noisy (how much?), but sometimes people exaggerate in order to favor the brand that has been bought versus the one that the neighbor bought.I'm really in doubt, clearly there are features that I find very attractive about both but I don't have the budget to buy both. That's why I'm "desperately" asking for opinions from those who have them.Thank you very much for any opinion you can give me.

content: Quote from: Tarloth on November 29, 2023, 03:23:46 amI have both the MSO5k and the DHO1000. Sure, the 5k UI now looks a little dated as compared to that of the DHOs but I find it perfectly useable in absolute terms. I don't perceive any lack of response, not to any significant degree. And as it has already been said, the physical vertical controls I actually prefer, at least in my workflows. It could be increased familiarity (I've had the 5k longer) but I actually find the 5k faster to use sometimes. YMMV. The DHO screen is noticeably brighter, which is welcome but it's also significantly more reflective, so it's a mixed bag.I initially bought the 5k rather than DHO, since I also am working predominantly in the digital/microcontroller domain. My rationale being that the best bang for the buck comes from buying features you will benefit from e.g. significantly increased sample rate rather than those you won't e.g. 12-bit resolution. Unless you're planning to work with small signal levels, the front-end noise argument is moot imho.Also, you're likely younger than I am and may hence have better eyesight but - I'm glad I went with 9" and 10" screens respectively. MSO operations with any significant number of channels on a 7" screen would be pushing it I think, at least for me. You can, of course, always make use of the HDMI output on any of these machines but only if you want a monitor on your workbench too.I'll add too that the reason I subsequently purchased the DHO was "because I can" and "it was cheap" (40% discount during Black Friday week) rather than needing to make up for any deficiency in the 5k. It could still find it's way onto an auction site yet.

content: Quote from: UK on November 29, 2023, 09:57:21 amUK, now I have a LA connected to a laptop. Decoding signals from the PC has many disadvantages for me, it is perfectly usable but not ideal. Among the disadvantages is that whenever I need to decode it is because I have to see signal degradation at the same time the error occurs, so then I have to use the external LA, the laptop and the oscilloscope and on top of that I see the analog signal on a screen and the digital decoded in another. I prefer to see all in the same screen in real time to see jitters for example.Another issue is that essentially the laptop plus the LA costs more than the oscilloscope, it's not as compact, and I don't have all the other features of the oscilloscope on hand or its robustness. Laptops can be fragile in field conditions and those that aren't cost much more than an oscilloscope in this price range.

content: Quote from: Fungus on November 29, 2023, 07:49:27 amThanks Fungus!, I understand that digital noise surely does not influence signals of at least 0.7 volts in digital, but how much noise does your unit have on analog the front end? Less than 10mv? Many times I evaluate sensors and when the signal varies slowly I use a very good multimeter and that's it, but sometimes the signal that I need to it process cannot be followed by the multimeter obviously and I need to see it in the oscilloscope, which is why I am concerned about noise. I don't need 12 bits (they are very appreciated of course) and I don't need the noise to be in the microvolts range either, but I would be worried if it is greater than 10mv. In the forums I have read atrocities about the noise in the MSO, I don't know if it is due to malicious people, poor measurement or defective units.Thanks in advance

content: Quote from: ebastler on November 29, 2023, 04:03:26 pmI will buy in USA today! I'll check that discount right now, thanks!EDIT: I just saw it, great price, but the DHO1000 series does not have a logic analyzer and I would prefer to integrate it. While it has more bandwidth than the 900 and a larger screen, it lacks a built-in signal generator too. The AWG of the MSO5000 or the DHO900 are not wonderful, especially when compared to higher budget instruments, but they are sufficient for me to evaluate signal adaptation circuits for sensors. It seems to me that the alternative is still the DHO900 or the MSO5074 (hacked of course). Thank you!

content: Quote from: Tarloth on November 29, 2023, 04:06:46 pmIt's not an absolute number, it's more like a percentage. Think of it as thick traces on screen.How much noise that represents depends on your vertical scale.There's features to mitigate it but they usually come with conditions, like needing a repeating signal and averaging several copies of it together ("waveform averaging" mode).As noted earlier though, it's moot for digital work.

content: Quote from: Tarloth on November 29, 2023, 04:07:55 pmYep, the lack of AWG and LA really hurts those two families. Like what are you even supposed to do with a 2 channel scope alone? Cannot decode any serial protocol and see the results the same time. Siglent has this nice feature that you can connect an AWG to a scope with an USB cable and the scope will do Bode plot with it, Rigol, this is missing. It's only software. I don't see why would you buy that 12 bit scope, unless it's your 3rd scope or something.

content: Quote from: tszaboo on November 29, 2023, 05:04:37 pmI don't understand you tszaboo, sorry, my English is not good and I'm probably missing your point. The two oscilloscopes we are talking about have 4 channels and both have at least one AWG integrated (included in the cost, the MSO actually has two but both enabled by a hack). AWG in rigols have the same functionality of siglent that is external via USB and a added cost. I consider a disadvantage and external device that could be integrated inside the same device. Both have BODE analysis (with limitations in the DHO900 and apparently some bug) but from what I observe with the same functionalities as the siglent. It is true that the siglent has, according to the reviews, less noise than the MSO, but no less than the DHO900.What would be your real point in favor of Siglent?

content: Quote from: tszaboo on November 29, 2023, 06:15:40 pmAhhhh, ok, yes, I don't dispute that the DHO1000 model has better analog characteristics than the 900, but I need the logic analyzer and to a lesser extent the signal generator, but I need both.

content: Quote from: Tarloth on November 29, 2023, 06:15:09 pmThe BIG weakness of the DHO900 is the sample rate when everything is turned on simultaneously. It's not enough.This is the decider for me.

content: Yes, the bandwidth of the DHO900 is really disappointing, 2Gsa/s would calm my concern.I really think that the MSO5000 is a better oscilloscope, I have to decide in the next few hours so that a friend can buy it in the USA and bring it here to Argentina. I am saddened by the fact that at first what interested me most about the DHO914s is the possibility of using it on battery power to decode signals in the field.Thanks to your information I was able to eliminate the ghosts read in the forums regarding the MSO5000, now unfortunately I have to choose between better bandwidth and portability.Thank you all

content: Hello to all. FYI: As of today and until december 31, 2024 Rigol North America has a 15% to 20% discount on all of the DHO line of scopes including the DHO800 and DHO900. Look athttps://www.rigolna.com/dho/for more detailed information. Myself I'm thinking about buying the DHO914S model just to play with it for a while. Take care and enjoy all your new scopes!
