Hi!
I bought one this week, and I'm very satisfied.
Although I have a 100 MHz Tektronix analog "old school" o'scope, I'd want try a DSO. I'm really impressed about the specs and performance.
Thanks for this product review.
Hi, it was my pleasure. Glad that it was helpful. Thanks for watching.
I bought and am using this oscilloscope you reviewed. I use it mainly for measuring power supply waveforms, and I think it is a very good product because it does not accidentally cause ground short. I know that there is no cheap and good product, but if it has such a variety of functions at this price, I recommend buying it. Appreciate your review 😊
Hello William, "You get what you pay" is what I always say, but in this case I think what you get is really good for what you pay. I really liked this scope. I totally agree with you comment. Thanks for watching and your nice comment.
Very good review! Thank you for your work.
I believe that this oscilloscope will be a good help for students, and anyone who has radio and electronics as a hobby, who has a small budget, or lives in small city apartments. This device has its place among users. Thanks again for your video, it left a very good impression on me. I subscribed to your channel
Hi Boris, glad it was helpful! review and thank you for the sub. Thanks for watching! 👍
Thanks for this :-) just jumped in and bought one - your review has backed up my thoughts on purchasing. Super cheap, but I really don't need it to do much!
Hello! Sorry for late reply, house move and vacations. Glad I could help and thanks for watching!
Very nice in depth review! Thank you! I'm always weary of these; I did not expect it to go to even near 120Mhz but for the price it still seems not bad especially considering that at the moment the Owon 272 is priced at $75 more on special otherwise it's $130 more. Worth considering.
Hi. Glad you liked it! Zeeweii produces very good and affordable devices. Pretty impressed with this one, the only that comes to this in terms of quality and price is the DPOX180H from FNIRSI, thanks for watching.
They say in the manual that if you use both channels then rhe sampling frequency it's half.
I also think that turning off the function generator will prevent interfering with the measurements. It seems that yours was on during the test as it shows the square wave in the bottom right corner.
HI, that happens in every oscilloscope. For example my Rigol MSO2102A has 2GSa/s on one channel and 1GSa/e if you're using both channels. The same happens for my awesome Micsig STO1004 has 1GSa/s on 1 channel, 500MSa/s when using on 2 channels and 250MSa/s if using 3 or 4 channels. I hope that helped to clarify the part of the sampling rate, normally the maximum sampling rate is only for 1 channel. The part of the function generator I didn't know, so I might do some videos in the future to see if that confirms, thanks for the tip, I'll check that out in a future video. Thanks for watching!
@TechCornerTV i checked the listing and they did mention something about your bandwidth being limited to 60MHz if you were to use both channels at once. Maybe i misunderstoof what i read but this was on the zeeweii official page on ali express for the product description
@TechCornerTV i checked the listing and they did mention something about your bandwidth being limited to 60MHz if you were to use both channels at once. Maybe i misunderstoof what i read but this was on the zeeweii official page on ali express for the product description
I read it again and it did mention 120MHz for single chanmel and 60MHz fordual dual mode
i dont have this oscilloscope but i think is good for technician repair like power supply, measuring mosfet gate or motherboard integrate circuit, boost converter etc... nice this is the second review i saw nice 👍 if you have time you can make another review with this oscilloscope in action making a repair of something where you need to see a signal of 12v or 5v......cool
Hi Leo, well I will do a showdown between those 5 oscilloscopes that I reviewd previously, probably in september, not sure yet since there is items arriving for review from manufacturers. I will try to add some test cases to my tests and reviews. Thanks for watching! 👍
Hi. Thank you for the review. Do you know if we can use the xy function of this oscilloscope as an IV curve tester without any additional component?
Hi, sorry I can't help you more there, I think you can but that not something that is on my knowledge bag. Thanks for watching.
if you have both channels enabled and long press F1 it displays the current waveform in red and blue. move the traces out of the way by changing the volts per div, etc., to see it. this changes it into a 4-channel scope for some circumstances! unfortunately the red and blue traces aren't captured by the save function
HI, good to know, thanks for sharing and for watching!
@@TechCornerTV you're welcome, and thanks for all the high-quality reviews. and thanks for using a normal voice -- some are just too excited :)
Nice review! While I don't think this instrument reaches the promised bandwidth, the manual specifies that for >100Mhz you need to run the oscilloscope in "overclock" mode, which is activated from the" Aux" menu by holding the "UP" key (it can be disabled similarly, with the DOWN) button. That makes the oscilloscope somewhat able to sample the signal, but the attenuation remains pretty bad. Enabling the second channel effectively halves the bandwidth because the sample rate is shared.
Having said that, oscilloscopes of this size normally don't have such a high bandwidth to begin with. Let alone with 2 channels plus function generator and TV output. Considering the features and price, the usable bandwidth (even if not as advertised) is pretty good.
Hi, I normally try to compare oranges with oranges, even if the orange tastes a bit like apple 😁 meaning, compared with the other units in this price range in the market, this one is one of the best, the only competition (in this price range +/-) is the FNIRSI DPOX180H, also a very fine unit. That said, this doesn't mean that the specs will be 100% met, but, comparing the all bunch, is one of the best. Thanks for watching.
With an X/Y mode, using it as a curve tracer would be fairly trivial. I ordered one of these.
Hi, it's a nice unit. I hope you enjoy your new oscilloscope, thanks for watching!
Do you think it’s still worth buying the new FNIRSI DPOX180H if you already have this DSO2512G? With this DSO2512G everything seems to be working properly, and I bought it but now I’m wondering if I should upgrade to the new DPOX180H because it includes better bandwidth, better resolution, possibly a better screen, and also color temperature. But I’m not sure if it’s worth it since I already have the DSO2512G. I need your advice. Thank you!!!
Hi, if you have the DSO2512G, you are well served. If you can sell that one, the one I would recomend to buy after is the DPOX180H unless you use a lot the FFT function, that is better on the DSO2512G. Thanks for watching.
Thanks for review. How would you rate dso2512g against Owon and Hantek handheld oscilloscopes?
Hello! It's on my plans to do a review showdown of all of these oscilloscopes, but they're are quite expensive, the Owon SDS2202S is 250€ only that one, so, I have to have a more sucessful channel to be able to do that... 😁 but, it is on my plans to review also those. Owon seems a very good device, one of the best by what I know, but not even that one has phosphor techology. Thanks for watching!
Thanks very much for your video. Can you please show how to capture rising edge and falling edge using this oscilloscope? I tried but couldn't success
Hello! Sorry for late reply, house move and vacations. Great suggestion! I will add it to the other requests I have for this device and make a new video asap with all these suggestions. Thanks for watching!
Can you probe smpsu primary circuit 300volt + ground problems?
Hello thanks for the review, I found your channel after I purchased this unit. I am a retired mechanic and service my own cars, being cars are getting crazy difficult to diagnose I figured with CAN and all the electronics like speedometers I can generate a signal to cluster to see if there is function, and at the same time look at the signal that goes to cluster if it is digital and if it looks good. A volt meter I don't think will cut it. I am hoping I made the right choice and some of your testing cast a shadow of doubt on this purchase. While I am going to teach myself on this for future use I hope I really do not have to use it, but at least in my mind I should be able to determine a waveform if it is good or bad. Thanks for a great video I just subscribed.
Hi, this oscilloscope is a nice unit, really loved it. One of my main concerns was the support, but now I found out that SigPeak changed the name to Zeeweii and they even have a website, probably we can get some support there. You will be ok with this. Thanks for watching and the sub! Really appreciated 😁
@@TechCornerTV So in concept I can get a usb video adapter and record screen on computer while in use. I cant wait to get it
@@carmo9693 Yes it works. Note, however, that the resolution remains 320 x 240. The picture does not become more detailed.
Hello. Got an oscilloscope? Have you checked the car speed sensor with a signal generator?
@@carmo9693 I've just checked and you don't have to worry about the lower resolution and/or stretching the video on a PC monitor.You can display the readout in a single window. With the right recoding software you can record *only* that window or portion of the screen, giving you a better image (and keeping the video file size smaller versus recording the entire monitor size). :) _(I'm considering getting this model for reason vs. others.)_
Where to find FW update for DSO2512G?
I found that real bandwidth of DSO2512G is 99MHz for 1 channel mode and 49,5MHz for 2 channels mode. Forcing higher frequencies makes strange visual effects as we saw on your movie at 27:00. On my device I have -3db signal level lost above 80MHz to it is quite good for me.
Hi, I found out after this video, that the brand changed to Zeeweii and they have a website, but you can get there by using the www.sigpeak.com. Try there. Thanks for watching!
How much does it cost in UK?
So this DSO2512G can provide a test signal and read it at the same time. As I understand things, the Hantek 2D42 will either provide one or the other, scope or generator, is this true?
Hi, never tested Hantek 2D42, but this one can do a loop, generate signal and analyse it at the same time. Thanks for watching!
What are the 2 small ports in the bottom, that you can plug the small alligator clips into.
Hi, I review this a while ago, probably the function generator output and or the AV/TV output. Thanks for watching!
between the dso1511e and the DSO2512G is the 1511 more convenient? more than anything for the firmware update? It seems that they do not support the older brother. Do you know of any bug that the 2512 has or how long it takes to charge the battery?
Hi, for me is the DSO2512G all-the-way, it has a bigger screen, more keys that will help the handling and I found out recently that SigPeak changed the name to Zeeweii, so you do have a website to give support and ask questions if needed. I didn't measure the time to charge the battery, but normally is between 1 and 3 hours, the charger is also important in this. Thanks for watching!
you will wish you had the two channels of the 2512. the battery takes a while to charge but it is a high capacity large flat battery fixed inside the case cover and lasts many hours. also should be easily replaceable if ever needed. charges with phone charger and usb-c. there aren't any bugs that i've found and i've used it a lot. but there are things like measurement functions on 2 will display but not work unless at least one measurement function on chan 1 is enabled. there are one or two other things like that but all can be worked around. very fun to use scope. latest ver has 2nd functions printed on case like a calculator to help remember them
Houston we have a problem. ADC is LQFP-48 looks like ad9288 or its analog, and this ADC could be overclocked exactly up to 120Mhz, so this device has 240 Ms/s . I dont know other ADCs in LQFP-48 package that has higher frequencies.
Hi Alexander, that will explain why they scrapped the IC... so you can't know that's a overclocked IC. Makes sense. Thanks for sharing and watching! 👍
Given Alising att 50 and 100 MHz respectively it obviously operates at 100 or 200 MS/s.
No video out ?
I had not seen any hint in the key page and the connectors at the bottom and not cable.
The Owon goes for 140€, so close to twice as much.
I hope to get the 1 channel one in a sale even though it is smaller and has its flaws. I would prefer they would have added such a big screen to the 1 channel device.
Hi, one fo this days I was watching Dave from EEVBlog and he said something rigth "on the mouche", he was talking about the DSO-TC2 but said that the manufactures should worry about making this works correctly instead of having a lot of functions, I tend to agree with this, a test equipment, first of all should be accurate, because... you're testing stuff! Those small devices tend to be not very reliable. But I see things from another angle, this equipment for me, is for people learning, students, etc, with a limited budget. Professionals, usually spend a few more bucks for something more reliable. For that kind of audience (hobbyist and students) this device is interesting. Owon, for me starts to be more professional. So you get what you pay, want better quality, need to pay more. Even so this a very interesting device. Liked very much. Thanks for watching! 👍
Thanks for the detailed review.
My manual of Version 9.14 says:
"7.5 Aux: In this menu long press the (Up) button to enter the overclocking mode (for measuring 100M-120M signal)"
I can't find any information on the internet where this feature has been tested.
I'd be interested to know how well this works, but I don't have a signal generator for these frequencies yet.
Do you know more?
Hi! I answer my own question.
Found an FM test transmitter and was able to test the Zeeweii DSO2512G (V.9.14) with it.
In overclocking mode I got a clear signal and measurement up to 118MHz.
You can see a screenshot showing the DSO2512G in overclocking mode at 118MHz (approx -4 dB) here
pwdev.bplaced.net/upload/DSO/118MHz.png
Hi, 941mV at 118Mhz is pretty good, what was the signal voltage? 1V?
Nice!
@@TechCornerTV
Hi! No, it was at about 64% of the amplitude of the 80MHz signal.
It is of course at its upper limit, but it still displays the frequency correctly and you get a relatively stable picture of the waveform. I was actually surprised that it can measure the frequency correctly in this range.
There are new reveals in the internet
overclocking mode: Menu -> Aux -> Up (long)
normal mode: Menu -> Aux -> Down (long)
In overclocking mode the DSO2512G can measure up to 120MHz (Hardware:v9.14 / Firmware:v1.2.8C).
The disadvantage of the overclocking (OC) mode is the fixed time base of 5ns.
You can't change the time base in this mode.
That's the reason why you don't leave it always on
FW version checking: Menu -> Set -> V (long)
Show/hide grid: Menu -> Set -> mV (long)
BG colour: Menu -> Set -> s (long)
High refresh: Menu -> Disp -> Run/Stop (long)
Video AV: Menu -> Set -> Run/Stop (long)
PC-USB: Menu -> Set -> ns (long)

Hi, thanks so much for this info. I don't have the time to research everything, but with this, maybe I will do a new video about it, because this unit is really cool. Has a good price for everything it delivers... again, thanks for taking the time to leave all this here 💪 Thanks for watching!
great stuff thanks
Do you know if this oscilloscope is compatible with the ammeter clamp ?;
Hantek cc-650
Hi, I supose it is, but is on my cart (thanks to all of your that used affiliate links so allow me this) to order 2 ammeter clamps and one of them will be from hantek, still not decided which will choose. I'll have a review on that also, so I can test here after. Thanks for watching.
Thx for the review. Does anyone know how to switch off the beep sound on key press ?
Found it in the Set menu :)
Hi, glad you found it 😁 thanks for watching!
Is there anyway that you can make a second part of this oscilloscope testing with overclocked (OC) mode and 200Mhz probes? Menu + aux + [up] (long) suppossedly said: 2 channel OC 60Mhz; 1 channel OC mode 120Mhz, the overclocked mode can be deactivated using same steps for activating that mode. Excellent content.
Hello! Sorry for late reply, house move and vacations. I have several other question about this device, I really considering making a second video about it. Nevertheless, I still need to figure it out, how to test the bw over 100Mhz of my function generator before. Thanks for watching and sharing!
@@TechCornerTVI think wey Will wait for an updates video thankyou have a great day! 😊
Thanks for your work!
I'm only considering two options:
1) Zeeweii/SigPeak DSO2512G
2) KKMoon DSO120M
Which of these options satisfied you more, what would you recommend?
Thank you!
Hi there, I'm all the way with the Zeeweii DSO2512G, no questions about it. Thanks for watching!
Many Thanks!
This divice is superB for money! Must have.
Hi, It really is! If they didn't scratch the ADC so we don't know that isn't really a 120MHz ADC and probably is a 100Mhz overclocked, it will be almost perfect. Thanks for watching and your comment! 👍
Where can you get the MA voltage board you were using?
Hi, you can download tit here or order a factory PCB for $5 ( www.pcbway.com/project/shareproject/mv_Voltage_Reference_Board_a39bdc74.html ). Thanks for watching!
Thanks! For the money - and my use case (tube guitar amps and analog effects pedals) - this seems perfect, especially to take on the road. A set of 100x probes (I noticed there was a menu item for that) and I can do almost as much onsite as back at the workshop :-)
Hi Mike, Rock on! 😁 you're right, you can select 10x/100x attenuation mode and it is a very nice scope. Now that I know that SigPeak is Zeeweii (changed the name) and they have a website and support, I do recomend it even more. Thanks for watching!
Does calibration (Menu -> Aux -> Calib) work for you? When I try, the device just hangs and becomes unresponsive forever...seems like a firmware bug. Do you have the same bug?
Hi Robert, I went to test mine again and it works ok... did you remove all probes from the BNC connectors? Even so, shouldn't hang. Is a process that takes almost 4 minutes... Thanks for watching! 👍
@@TechCornerTV Yes, I had removed everything. But, thanks to your answer here, I just now discovered that you need to be in AUTO mode (I think?) before running this calibration. It then ran and completed in 2 minutes. Thanks!
Hello and thanks for your review. It's the one that convinced me of buying it. I'm currently studying biomedical engineering and I bought these little oscilloscope to test my circuits without having to go into my school's labs. However, is there a chance you know why I can't test a negative half wave rectifier? I'm connecting the function generator integrated here as an input but when it comes to the output, the only signal I get it's a pulse. I already tested my circuit with my school's equipment and I'm able to see the negative output without a problem, but not with this oscilloscope. Is there any way to fix it? Thank you in advance.
Hi, thats a pretty specific problem... maybe it is some problem with your unit or just a bug in the firmware, try to leave a message in www.zeeweii.com to see if they help you. If they do, please update me later, I would like to know if they're responsive or not. Thanks for watching!
@@TechCornerTV yeah, it surprised me too because I haven't encountered any other issues with this little device and it has been working well for its intended purposes. Maybe it's a firmware issue and I hope they get back to me soon. I'll update you if they do :)
@@Acid_Lexa I'm not an expert, but maybe the built-in generator doesn't provide enough voltage for the experiment?
It delivers 2.5 volts amplitude, i.e. 1.25 volts per half cycle.
What you are trying has to do with diodes. See "forward voltage". This is typically around 0.7 volts.
Thanks!
Hi, thank you so much for your "Thanks", you're the first to give a thanks contribution to the channel... really appreciated! Thanks again!
Esse aparelho é top! Nada de ruído.
Olá Marcelo, agora o DPOX180H já é concorrência para ele, mas deve ser o único nesta categoria, este DSO2502G é do melhor que já tive aqui nesta categoria. Obrigado por assistires!
Thanks for this. I almost made my mind. The only thing I am missing, is a link to to a recommendation for the immediate next tier in quality/range. You mentioned something about a "a bit more" but have no idea how much that bit is. So an affiliate link to such a device would immediately relieve the doubt I currently have.
H Fabio, don't get it exactly where you mention "a bit more" probably in relation to the other 5 oscilloscopes I reviewed in this serires, but the affiliate link to this one is here geni.us/qnxcGmi . Thanks for watching and your support!
@@TechCornerTV Hi I am sorry. I mean that you have mentioned around minute 53 that we'd need to add 30 or 40 euros more to get something that would cover that range, but didn't provide a link to it (first time I didn't hear you say the amount). In the mean time I found something, which looks promising because not only 180MHz is advertised, but also have seen very good reviews from the brand. I want something to get me covered for the most amount of applications, special arduino troubleshooting and prototyping. It's twice as expensive, but it seems to cover everything I want and looks like a good candidate for me to relearning how to use an oscilloscope (it's been 20 years). Also think it would be a great candidate for a review: FNIRSI DPOX180H Handheld Phosphor Digital Oscilloscope 180MHz -3DB 50000wfms/s Dual Channel 20Mhz Signal Generator ZOOM XY FFT

What do you think?
Parabéns pelo canal, muito bom. Sucesso!
@@fabio-franco
It always depends on what you want to pay and what you need.
The more you pay, the more you get (hopefully).
The FNIRSI DPOX180H simply costs $50 to $60 more than the DSO2512G. That's quite a difference in this price range.
Personally, I would hold off on the DPOX180H.
It is brand new, there is no test above 100MHz yet afaik and a few firmware bugs are already known.
@@paolotestarelli2768 Really appreciate your reply, thanks for that. I am looking for a the best cost/benefit solution and that is still not prohibitively expensive (for me). The price of DPOX180H (at face value) seems to bring the best bang for the buck and it is on the limit I am willing to pay. I don't mind bugs now, as long as I can patch them later. However, I do agree that I may not be the best candidate for early adoption, but I do want something sooner rather than later, and I do not want to buy any other oscilloscope for the foreseeable future. What attracted my attention to it was:
1 - High range (although I don't have independent validation, they seem to deliver what they promise)
2 - Portable
3 - Dual channel
4 - Signal generation
Spec-wise my only point of attention, which I am not savvy enough to determine, is whether the sampling rate may be too low. I suspect it may be the case.
Nevertheless, I appreciate your recommendation and will not buy this one yet. So I either wait more (which I hope not too long) or I manage to find something that fulfill my requirements above and is a safer alternate at similar price range.
Hi. Is this also a rf generator? Can it be used to align tuners, receivers?
Hi, I don't think so, it's a function/signal generator (square, sine, etc). If you put anything more in this, it might blow! 😃 Thanks for watching!
@@TechCornerTV thanks for the reply. Can you recommend a signal generator for tuner/receiver alignment? Is it supposed be a rf signal generator specifically?
A defasagem das duas ondas senoidal em 25 MHz é normal? Eu vi que até 10 MHz estava precisa.
Olá Marcelo, 25Mhz é um bocado, no geral este é para mim um dos melhores osciloscópios "pequenos" do mercado, juntamente com o DPOX180H. Essa questão, pode às vezes ser falha minha na análise. Obrigado por assistires.
The listing on the official ali express site mentions your bandwidth being limited to 60 MHz for each channel when using dual channel mode. Maybe that was the reason for the issue when checking bandwidth ?
Hi, well noted. I will try to get time to do a showdown between all this small oscilloscopes and will try to better test it at that time. Thanks for you comment and for watching.
@@TechCornerTVaha that would be a great video but I believe this dual channel one on this video is the best for money. Also thanks a lot for making quality videos for these products I was looking to buy an oscilloscope and was gonna settle for the entry level zeeweii single channel one but then I realised how useless it would be specially considering how tiny it was with no video output. But thanks to your videos I'm gonna order one of these dual channel ones. Wish they had any 4 channel ones but it would be likely out of my budget.
is dso2512g superior to dso1511? How big is the difference between one and the other?
Hi, I have also a video of the DSO1511G, but in a nutshell, the DSO2512G is easier to work, since it has more keys, bigger screen, 2 channels, XY mode. The rest of the function are pretty similar to the DSO1512G. Thanks for watching.
That shared folder only has files for some dso1511e device.
Hi Marcus, that was I thought also, it's a pitty, as I told in the video, the main I have with this oscilloscope is the inexistent support. We are not talking about a bad support, it's simply inexistant, we don't know where this came from and how to complain of a bug or something like that. Other that, for me, from all the five analyzed, this is the winner. Thanks for watching! 👍
Hi loving the videos, I’m in the market for a small oscilloscope and wondered what you consider to be the best value for money to get me started, I’m looking to spend up to about £150 here in the uk, many thanks in advance.
Hi, the answer is always "depends" 😁 but if you're on the small and mobile, I'll choose the Zeeweii DSO2512G 2-ch (120Mhz) for a more accessible price oscilloscope or the Owon HDS272S (70Mhz), you have this Owon up to 200Mhz but it will not fit on you budget. In terns of bench oscilloscope, you don't have much choice, FNIRSI 1014D is basically your option, if you squeeze some more bucks you can go to Owon SDS1102, a better device. Thanks for watching!
thank you
Hi, glad it was helpful. Thanks for watching.

Hi! Happy to help and thanks for watching.
How it work with cars signals diagnostics
Hi, you can use it to diagnose car troubles, it's not my area, so I can't explain how. But you can use it for that. Thank for watching! 👍
it doesn't have any special functions for cars, but if for some reason you needed an oscilloscope to use on your car it would be convenient. one of those bluetooth modules that plug into your car diagnostic port + a phone app has been helpful to me for telling me what part on a car is broken. i read the cheapest of those are not good though
Спасибо за подробный обзор.

How can I connect 1:20 attunater
Hi, well you can use one, but probably will have to do the math yourself, because suported by the firmware is only 1x and 10x. Thanks for watching! 👍
Do you know if the Dso2512g is compatible with the ammeter clamps?
Hi, Zeeweii doesn't supply those probes. I'm sure that if you connect one, you'll see some information on the screen, but I don't know if it is prepared to work with one. I have to get one of those probes to test it on my devices. Thanks for watching!
Where can I find find the firmware update??
Hi Dean, if it is available should be on theirs website www.zeeweii.com, Thanks for watching.

How do You rate DSO2512 against Fnirsi 1014d? Im considering buying one of them.
Want to analyse ignition signal on cars and small engines, starting pulses on electrical motors, plus power supply signals etc.
Hi, it is much better as an oscilloscope, a lot more functions and more precise. The only low point when compared with the desktop 1104D is that the screen is really small to use it as a bench oscilloscope. Thanks for watching.
In my opinion the difference mainly is the ease of use that 1014, there is a seaperade button for each function which for me makes a difference in practical work
Esse monitor possuí entrada RCA?
Olá Marcelo, penso que estejas a falar da TV que utilizei no video, é uma TV com entrada SCART e usei um adaptador (SCART -> RCA) para ligar ao osciloscópio. Obrigado por assistires.
there is an overclocking mode
Hi, yes there is, at the review time, I was not aware of it. Thank you very much for sharing and for watching.
Which one is better? 1511G or this one here?
Hi, in terms of performance, they're pretty much the same and also in functions. I prefer this one because gives you 2 channels and also has some more dedicated keys that makes the usage easier. Thanks for watching!
Pay special attention to min 33 in video. 100Mhz signal is detected as 2Mhz signal in the scope Why is that?
Hi, I went to see and notice. Sometimes when you change the frequency, you have to auto the devices (especially cheap devices like this one) to "reset" the values and fix everything. But yeah, not ideal. Thanks for watching!
Read up on sampling rate, Nyquist and aliasing for the answer. Very surprising that even the reviewer does not appear to understand these fundamentals.
Can someone tell me if it worh bying this over hantek 6022be osciloscope
Yes! ;-)
But these devices are very different.
So it depends on what you need.
@@paolotestarelli2768 could you tell me what's the difference that you see between them, and how it affect the use of the osciloscope
@@paolotestarelli2768 thank you in advance
@@MadaraUCHIHA-hy9xe The Hantek 6022be is a USB oscilloscope. It doesn't have a display or buttons, so you need a PC to work with it, and it has a much lower bandwidth.
But you can see that yourself, right?
@@paolotestarelli2768 of course I know about this, also you can use it with android devices, so it has mobility option, and the option to visualize the signal in large screen to better view what happend.
Однозначно лайк!
Hi, thanks for your comment and for watching!
It's worth it now 2023 ?? It there some bugs or it's works well ???
I'm currently not aware of a better device for this price.
It's well made and easy to use.
You have to decide for yourself whether it meets your requirements.
Hi, I have to confess that I don't use it everyday. But for the tests I made and all the positive comments I read from viewers here in the channel, I pretty sure that it is a safe bet. I will not garantee that you will not find a bug, but I not aware of any serious problems with it. Only positive feedback until now. Thanks for watching!
is it a true 120mhz Oscilloscope?
Hi, I don't have yet a function generator that will allow me to test it over 100Mhz, but for the reports I have, you have the turbo mode that will give you the 120Mhz. Thanks for watching.
DSO2512G vs FNIRSI DPOX180H?
Hi, DPOX180H for almost everything, DSO2512G for FFT and Video output. Thanks for watching.
@@TechCornerTV do u think DPOX180H actual mhz is higher than DPO2512G?
Hi, device has 500msps / 2 channels = 250msps . So for 50mhz signal it has only 5 points. And because of frequency deviation you've see an amplitude modulation. IT IS OK due to physics))
There is other problem with real bandwidth, signal level is decreasing after 5Mhz .
Hi Alexander, yes it was to be expected some deformation on the waveform, because of its limitations... even so, it went a bit bezerk! But I do still the bigger problem of this device is the lack of support. Aliexpress gives you 15 days to open a case, after that you're on your own... and that's a pitty, because I do think those oscilloscopes (DSO1511G and DSO2512G) are above the rest of the competition on their price range, in everything! Event if the 120Mhz announced bandwidth is lower in reality. Thanks for watching! 👍
Generally, i've ordered this device after your video, looks like that is very chip but it's problems and limitations are acceptable for 79$ price.
Since it gives aliasing artifacts at 50 MHz with 2 channels it seems to be 100 Mega samples per second for each channel, (maybe only 50?). 500 Msamples per second is false marketing.
The specification indicates that the maximum supported bandwidth in 2 channel mode is 60M.
Hi, you're right, I went to see the specs and now they show that. Thanks for this info and for watching!
I recently bought this exact thing off Amazon (very quick shipping). The only reason is to measure the speed of light, using a couple detectors + laser. I'm still waiting for loads of detectors & an IR laser to arrive, but I've got a couple LDRs set up. I can't yet rule out a speed of like 2*10⁶ m/s (2000 km/s). It is much faster than I thought (I was thinking as low as 8 km/s). I can set up a 23m path difference but haven't done it yet because I'm not sure exactly what circuit will give the best possible signal (after triggering, etc). I've never seen actual evidence that light is electromagnetic - ppl just assume it is since it should have a similar speed to radio. Optical fibers conduct ultrasound, light & EM - supposedly the whole internet uses IR but that seems unlikely to me.
Wow! Hightech there 😁 thanks for sharing your experience!
Finally, someone actually doing science, instead of saying "cuz science" regurgitating old theories and bashing new ideas. Its amazing how differnet things can be if we just look, and thankfully these tools are giving the rest of a chance to peak, even if we dont know what we're looking at.
“Bandwidth 120M(ch1 only),dual channel mode is 60M.”
Yeap, completely true. I will do a video comparing all the devices, I reviewed under $100, I will get the record straight in that video. Thanks
Where is a bandwidth test with a square wave? I need a square wave test.
You can distinguish a square wave from a sine wave up to about 40MHz in single-channel overclocking mode with appropriate probes.
Hi! To test the maximum of the oscilloscope you cannot do it with a square wave, that's why is usually "forgot" in this tests. The only wave that will go to the maximum bandwidth of the oscilloscope, is the sine wave and that's why is commonly used in these tests. I will pay more attention to show better the square wave in the future. Thanks for watching!
@@TechCornerTV Hello! Everything that you said is absolutely obvious to a person who has extensive experience in using oscilloscopes. At the same time, it is almost incomprehensible to a beginner who chooses his first oscilloscope for purchase. Of course, I understand that the shape of the signal displayed on the screen will directly depend on the number of its odd harmonic, which the analog circuit of the oscilloscope can let in. But I still want to see at what frequency the meander in this oscilloscope becomes indistinguishable from a sinusoid. Thank you.🤗
@@paolotestarelli2768 Hi. I ordered my DSO on Ali a few days ago. There was a good discounts and it cost me less then $70. When it comes, I will experiment. In the meantime, I have no idea what quality his probes are. I hope they are at least not much worse than my chip P6100 probes.🙂
@@user-io3yy9vp9nThe device comes with two P6100, which is OK for the price. However, it is also clear that 100MHz probes are not sufficient to test the limits of a 120MHz oscilloscope. By definition, 100MHz probes already have -3dB at 100MHz. I ordered a 250MHz probe for this reason.This also makes a difference with a 40MHz square-wave signal, which can hardly be distinguished from a sine wave with the standard probes. A ground spring can also be helpful.
This review was useless for me. I was interested to see square waveforms in different frequency ranges (MHz).☹
Hello! Sorry for late reply, house move and vacations. I'll try to keep in mind to test the new devices with the square wave also. Spoiler alert, I have a new Zeeweii oscilloscope to be delivered in the next days, so you can count with a new Zeeweii device review pretty soon. Thanks for your comment and for watching!
With 500ms it's not able to digitize 100 Mhz. DSO for 100Mhz have a sample rate about 1 GS .
Hi, thanks for sharing this and thank you for watching!

Hi, sorry the late reply, trying to keep up with the comments, not easy. Thanks for the support and for watching.
AV out is a perfect example od bullshit feature
Hi, don't agree with you. For me those screens are quite small, the idea of the AV is also giving you the chance of better using the oscilloscope in a desktop environment. Not perfect, but it is an option. Thanks for watching!
