Thanks for the very detailed review as usual Hugo. I really appreciate all the effort you put into making and editing your videos. For the price, this scope is actually very good value. And even though the bandwidth is a little overstated, 15MHz is still very good for that price. It's amazing how technology has evolved so fast and how cheap some test equipment for hobbyists are now. 10 years ago we would never have imagined we could get this type of scope for such a great price.
Hi, my pleasure!, you're so right! I remember that when I was kid, the electronic kits where so expensive... with the price I paid my JBC 40W soldering iron, I could by a soldering station with today prices... well, this part I think still is true 😁 thanks for watching!
Thanks for another thorough review. 15MHz is not bad considering it's advertised at 18MHz. That's actually a conservative marketing claim for this type of scope as most claim bandwidth more than 3X their real bandwidth. The signal is still useful at 18MHz.
This scope is only US$28 *without* the battery, though. It's currently $36 with the battery and I'd consider the battery a necessity with this type of scope as it's annoying needing to have it plugged in all the time. The battery also gives you full isolation, which avoids potential problems with some circuits.
I'm not affiliated with them in any way, but it seems to me that this SigPeak/Zeeweii company is actually innovating in this product category and not just putting older, slower designs into nicer packaging like Fnirsi sometimes does. I hope Zeeweii continues to improve their sub-$100 products and perhaps one day make a scope to challenge the Fnirsi 1014D, which is surprisingly overpriced for what it does and how much it costs to manufacture (no power supply, for example).
I think it's sad that Fnirsi's 1014D has been so successful as paying just a little more money would buy a vastly better scope from another brand. I've seen 1014D's priced at close to $200, which is simply a rip-off, in my opinion. Good luck to Zeeweii ;).
I'm not opposed to a USB-powered bench scope and think it's actually a good idea for reducing the cost, *but* the resulting product should sell for less than $100, not $180.
Paying $36 you also get the proper oscilloscope probe, which costs about 8 dollars on its own.
Hi, thanks for the comment. I have to confess that I order the non battery version and they sent me the full kit, as I said before, I was in contact with Zeeweii. So, it was not sent free, but at least I received the complete kit with battery, but I only notice that it existed the version without battery after you post, I went back to check what I had bought.
Regarding the price vs what you get and even if I'm a FNIRSI fan, the DSO138 PRO with 200Khz bw and 2.5MSa/s cost arount the $35, if compared with this one that has "18Mhz" and 40MSa/s and 8 waveforms function generator, there is no decision to make, the DSO155 PRO is a non brainer purchase.
I think Zeeweii is still a very small company, thats the idea that I got, but with some talented people on R&D because they have their own models. I hope that they grow enough to create a decent support channel to the end user and to be able to improve their products. They are quite ahead of the rest of the competition.
Thanks for watching!
Thank You for review, I was curious on this one.
HI, my pleasure. When I saw it the first time, I knew I had to review it 😁 Thanks for watching!
Thanks a lot for the detailed review!))
Hi Andrew, glad it was helpful! Thanks for watching.
Most of these little scopes always seem to fall flat one way or another and range is usually exaggerated. This one actually seems reasonable. Plus it has a built in function generator!
Just purchased with your affiliate link to be a little stand in and portable unit until I fix my BK Precision.
Thanks for the work you put into the videos and reviews. Always love listening to someone who clearly has a passion for what he does and the equipment he uses.
Hi, thank you so much for your nice comment! It really matters to me. I'm so glad that the review helped you and thanks once more for the support of using the affiliate link ❤ and for watching this video.
I picked one of these up as my first oscilloscope recently to learn with. Thanks for the in depth review
Hi, glad it was helpful and thanks for watching!
Yep, I got a Rigol 1054Z then realized I don't want to accidentally destroy it while learning. So then I got the handheld Owon 100Mhz model -- then I heard of the Zoyi zt-702(&3)s and decided I didn't want to blow up my still rather expensive Owon scopemeter, so I got those as well (giving my old zt-702s to a friend that has never had a scope and works on cars). ...... THEN I heard of these ZeeWeii scopes that seemed like the real deal compared to some others like Fnirsi, so I got this 1054 Pro model as well as their '125' Mhz single-channel model (1511G, IIRC?). I'm finding that these ZeeWeii's don't seem to be the normal 'toy-kit' types at all - they seem very real indeed! So in the future I'll continue to support ZeeWeii for their innovations in this cheaper market.
...And yes, I'm a firm member of TEA - Test Equipment Anonymous. 👍
Very nice and comprehensive review. Thank you!!
Hi, glad it was helpful. Thanks for watching!
awesome stuff man, I just picked one of these up to integrate into a 3d printed project, found this very informative when doing research for it.
Hi Mike, glad to hear it! Thanks for watching.
Thank you for this review. I had just picked one from online store in our country. This is my first bought oscilloscope and i really love it. You have done great review of this. Nice done
Hi, glad I could help and I hope you enjoy your new oscilloscope. Thanks for watching
Great review ,thanks for this great detailed review.
Hi, my pleasure and thank you for watching!
Noted the USB to serial chip....
That suggests either a capability to flash the firmware, or to externally control the device, or to output to a PC....
Hi, probably to flash the firmware... thanks for watching!
I just bought it and after i saw its great signal generator i was impressed ! This sounds so good ! One question though, is it updatable as other or does it run on this firmware for ever ?
Hi, I think it is upgradable, but to be honest I'm not aware of any update for any of the Zeeweii devices. Regarding the DSO153 it really is a master piece, I think zeeweii is totally underrated, they have quality products for very good prices. Thanks for watching!
@@TechCornerTV thanks alot for the feedback. I just wanted to make sure that if there are any updates regarding the small oscilloscope as in software there is a possibility. Off course i think it is a very great tool. I am not really into electronics that much so a advanced oscilloscope was not needed thus making this zeewei oscilloscope awesome.
I also ordered this oscilloscope. There is a small question: the value of the output impedance of the internal function generator? Is there a buffer amplifier at the output of the generator?
Hi, I know that it has fixed amplitude, but in terms of impedance, I don't know to answer that. Sorry. Thanks for watching.
@@TechCornerTV I just received a response from the seller - the impedance is 150 ohms. This, in my opinion, indicates the presence of a buffer operational amplifier!
High SpeedRail-to-Rail Amplifiers AD8091, 110 MHz, −3 dB bandwidth (G = +1)
@@user-ie4td2mq8x well its 3.3v rms so my guess is ut has a op amp in it
Hi - very good and very convincing review. If I buy this DSO154 Pro scope I will certainly use your affiliate link.
I am comparing this to another small scope which lists a sample rate of 1Msps 12Bits - can you advise what this "12-bit" sampling feature does and how does it compare to the DSO 154 ?
Thank you.
Hi, in this size, up to $50 I don't know any better than this. You can have a better ADC but if you have 40 to 80 times less samples per second, that can be a bummer in terms of data to display the waveform. Is true that this a bigger sampling rate because it goes up to 18Mhz, but, it will have the same sampling reate in lower frequencies like the ones in its price range. So, in this price range, I would not mind a lot of the 12-bit. At least this is my way of seeing it, until someone show me that I'm wrong. Thanks for watching.
This one over thr dso 152 153 and pretty much any fnrsi. This device is impressive
I'm looking for DSO TC3, but this one appear to be more interesting for the price. I want to use this for a CMP/CKP signal viewer, and maybe for check if vehicle CAN signal (500Khz) have noise or is clean. Do you mind this one is good for my purpose?
Hi, if you're looking just for the oscilloscope function, you'll be all right with this one. I will advice the 18Mhz version. Thanks for watching.
Do you happen to know know max voltage this can measure? I see one value for x1 and another for x10. But don't know the difference between the two. Safe to think that 40v is actually the max.
Hi, the max voltage is 40V, but if you use the 10x attenuation of your probe, you'll be able to measure voltages up to 400V. It doesn't depend on the oscilloscope but on the probe, so, please be sure that you select 10x on the your probe switch. If you do so, please change the probe compensation to 10x in the oscilloscope so it converts the values according the 1x or 10x. Thanks for watching!
Is it possible to show notifications on the computer
Hello! Sorry for late reply, house move and vacations. Don't think so, at most you could do an firmware upgrade. Thanks for watching!
Great review and I'm currently awaiting delivery of this item. :)
Is there a proporietary plug/connector to inerface with the function gen. output pins, or does rely solely upon use of probe type clips?
Answering my own question posed above: I've sourced a 'Clever Little Box CLB-JLB75 CLB-JL-75 BNC Female to Terminal Block 2 Pin' (the actual eBay description @ £2.68 inc. shipping) that has twin screw terminals on one end and a male BNC connector on the other. Using the screw connector to secure it to the function generator pins of the DSO154 PRO, this male BNC will allow interface with any kind of female BNC flying lead terminating in alligator clips and/or banana plugs as required.
Hi Andrew, I saw you answer also and I also have a few of these connector laying around here somewhere :) I'm glad you solved your issue. Thanks for watching. PS - Sorry the late reply, but time is really short these days.
U8 IC should be the FPGA. They have 2 versions of the scope. The cheaper one has only 1 Mhz Bandwidth and has no battery and no probe.
HI, a small devide like his makes more sense with battery, in my opinion. For price difference, I prefer also the 18Mhz version, but there is a solution for every pocket. Thanks for watching.
Would this be suitable for measuring an inverter's sine wave output to check if it's pure or modified"
Hi, I think it will. Thanks for watching.
I don't see any capability to upgrade the firmware , NEITHER an FFT analysis , but then again looks to me a bargain IF IT IS RELIABLE
Hi, yes, no FFT and I don't think you'll have a firmware upgrade. But for the "small" oscilloscopes, this is very accessible and precise and go up to 15Mhz (18Mhz officialy, but yeah). Thanks for watching.
@@TechCornerTV FNIRSI has both of them. (upgrade +FFT) Ever much simpler than "weebii" and with limited bandwidth to 200KHz
Do you know if Sigpeak is going to realise a tablet oscilloscope in the near future?
Hi, it will be great if they do, I don't know but I can ask 😁 Thanks for watching!
@@TechCornerTV Indeed, I meant "release" in stead of "realise". But would be great if you could ask. Thnx
Is it possible to record waveforms in memory?
Hi, in this oscilloscope that is not possible. Thanks for watching!
Compare to FNIRSI 153, which one will you recommend?
Hi, this is a different kind of beast 😁 DSO-153 is more polished, better UI and case, this has more horse power, support 18Mhz (in the 18Mhz version) is still that almost DIY kind of look, but it is a very nice oscilloscope, if you need the bandwidth, I certainly stay with this one. Thanks for watching.
Supplementary question: I'm keen to reduce the output of the function generator (circa. 3v PKPK out-of-the-box) to emulate a guitar signal level for front-end pre-amp fault finding purposes.
I had assumed this would be possibe from within the menu, but have been unable so far, to finding a setting? Something I need to do externally via a bespoke potentiometer arrangement?
Hi Andrew, yes, you need to do it externally. These cheap devices normally have a fixed amplitude on the function generator output. Thanks for watching.
For this specific unit can you run the signal generator and the oscilloscope at the same time ????
Hello Terence, I think so and if I'm not wrong I have it running during the video recording. Thanks for watching!
i think thia ia better option for me, i recently got the DS0138 DIY kit, on completion the screen is all white and unuseable.
thanks for the detailed content.
Hi, I loved this little fellow, nice specs, acceptable bandwidht and killer price. Thanks for watching!
@@TechCornerTV I just received my DSO today after so much testing i can tell you that I have no buyer regret, Thanks for the guide.
mate maybe u soldered something wrong
but either way that scope is outdated and weak as heck (in terms of dirt cheap scopes)
Thank you so much. It seems that 15 Mhz is only suitable for periodic signals. The method could be sixteen possible offsets from the timing signal, allowing a 1Mhz analog-to-digital converter, hence the price? Could this be the role of the multiplexer?
Hello! Sorry for late reply, house move and vacations. I'm more inclined to the ADC... but my knowledge is very limited, so maybe. Thanks for watching!
I got tge one thst looks like the video game controller (the buttons are on both sides) abd im not likeing it no no constructions I don't know how to update it don't know where to go to update it it needs hardware and software updates apparently and the button layout in the way that you go through all the different settings is just not user-friendly imo
I almost got the 1-year reviewing in this video though because I like how the function generator prongs are sticking out mine their recessed and you need to use very tiny little clamps to get to them
Hi, yeah, I already saw that one in AliExpress but never though of buying it for review, sometimes they simply don't think in what they're doing. That one seems to have a very poor UX and you just have confirmed it. This one is very acceptable for the price and the product line/target that it was designed to. Thanks for watching.
which oscilloscope is better, zeeweii 154pro 18M or tooltop et120m? greetings from Poland :)
Hi, I think you're comparing apples and oranges 😁 for me, the et120m is a more complete solution and with a higher bandwidth support. This doesn't make the 154pro a bad device, not at all, for the category it is comparable (dso150, dso152, dso153, dso138) is in my opinion one of the bests. Thanks for watching!
beetween this one and fnirsi dso-152 what would you recommend?
Hi Juan, this one for sure. I love the DSO-152 and all the design, user experience, but this can go up 18Mhz... is more than many portable oscilloscopes and multimeters like the 2C23T or the ZT702S. Let me give you some news, very soon that will be available also the DSO-153 with 1Mhz bandwidth, should be released in next weeks. Thanks for watching.
@@TechCornerTV thanks for answering, really apprecciate it
The 154pro for sure basically over any fnirsi I have tried so far.
Nice run down. Thanks. However, you are using a 50 ohm cable and your generator probably has a 50 ohm output, but you have not terminated with 50 ohms at the scope. This impedance mismatch will lower the BW you measure. Try it again with a 50 ohm passthrough (or even 'T') terminator.
Hi, ok thanks for the tip, I do appreciate it. I will try not to forget the next time 😁 thanks for watching.
PS - Sorry for this late reply, time to reply is really short these days.
@@TechCornerTV No worries!
u8 fpga Lattice?
Hi, sorry didn't get the question, can you explain better? Thanks for watching!
Probe sold x10 or not
Hi, yes, the probe can go to 10X. Thanks for watching!
Good afternoon. I am from Ukraine and bought dSO154pro version of 1 MHz no batary judging by your review I can say for sure that my 1 MHz device is exactly the same in bandwidth as your 18 MHz. Even those saw defects from the bottom. Thank you for your review
Hi! Slava Ukraini 😁 Thanks for sharing and for watching! Best of luck to you.
Perfect. This is exactly what I've been seeing from other users whom have bought the unit without a battery. They seem to be exactly the same! 😄🌎✨
@user-rk1bt2ke8c What is the max. signal generator output freq. of the 1MHz model? 1MHz. other 500kHz?

Thumbs down for the amount of commercials
Hi again, sure, thanks for watching anyway.
This is a comment just for reflection, the one thing in the world that you can't buy or get back is time. This video took about 8 to 14 hours to be produced, counting, recording, edition, photos, etc. Since I have a daytime job that I love, I usually work at night, some times up to 3 to 4am, so, you can imagine this takes me 2 to 4 nights to get it done.
The revenue I got from those ads until the time of this reply and after 4 months being live was about 1/4 of the cost to buy and to deliver this to me.
If you count the time I spent in here and I will never recover, you can understand that the ads are a smell help for at least don't have monetary negative result of this. I wil have this device paid in 1 or 2 years after of the video launch time. I don't do this for the money, neither the equipment, I don't need this oscilloscope when I have a Rigol MSO2102A bought before I even had the channel.
But what I found out in the past and motivates me to spend my time in this is, that electronics is a very expensive hobby and when you don't have a lot of money, a informed decision helps.
That's why my videos are long and try to show everything I can, about the device, that takes time and money, but I do it because I consider myself a priviledge person, I leave in europe with social security and "free" medical health and the videos are also seen by people that have to decide to spend the money to buy this or have better clother or food, If I can help in that decision process of a very scarce money resource, I'll be happy and the goal was accomplished.
That's why there are ads, is a trade off so you help me also, at least, I will spare only my time and somewhere in the future pay the cost of the equipment, allowing this way to continue the cicle to have better information.
I understand that on a perfect world ads will not exist, but if you find that world just let me know... 😁
