Just bought a DSO-153, just a note to others, auto calibration is not covered in the manual, nor by Hugo in the vid. To auto calibrate hold down the AUTO button until you get message "Awaiting auto-correction" wait for message to go, about a minute, then it is ready to use. Hugo great vid, convinced me to give one a go.
hi, I did accidentally hold AUTO and it's stuck in the "Awaiting auto-correction" on screen and buttons are disabled. What am I supposed to do now, plug the probe into the 1kHz output or something? It's basically locked now...
Hi, auto electronics is not something I do, but for all other comments from users here in the channel, yes it is. This one can analyze frequencies up to 500khz and 400v Vpp, so you should be alright. Thanks for watching.
Thank you for the review Hugo. I noticed one problem with the scope when you were charging the device while using it. As soon as you plugged in the USB cable, the square wave started jittering up and down. This is most likely due to either the USB charger being a switch mode power supply and the noise from it is affecting the reading or the BMS inside the scope is causing the problem. However, I’ve found that many cheap handheld scopes have this same problem when you charge it while using it. Apart from that small issue, I thinks it’s a great little scope for a beginner.
Hi, nice to see you again, once more you're right. When recording didn't notice, I was concentrated in another topic, but yeah, you see there the power supply switching. Thanks for sharing and watching.
@khuongathebounga4141 back to working while charging, I tested with another charger I had here, while asked if it will work ok with a Type-C to Type-C cable for charging, and I notice that with this second charger the signal was much more stable. It should have some kind of protection to prevent that interference, but also, made more clear that the other power charger was piece of garbage 😬
@@TechCornerTV thank you so much for testing that. I appreciate all the effort you put in retesting equipment if something comes up in the comments. I 100% agree with you. They should have put in some kind of filter to reduce the ripple noise. It’s a pity as it would be extremely cheap to do so, plus it’s even more important in this case because oscilloscopes are sensitive to picking up external electrical noise. As far as I know, linear USB chargers are now very uncommon & hard to find since they are more bulkier, heavier & not as energy efficient as a switch mode power supply. So the scope manufacturer should have taken this into account. However, a good thing about you testing it with a different USB charger is it confirms the jittering was due to the charger and not the scopes BMS. Most cheap chargers that come from dollar stores or eBay, etc have too much ripple noise, whereas most, but definitely not all name brand chargers that came with your phone such as a Samsung or iPhone were less prone to ripple noise, not to mention much safer. Also ripple noise will degrade your electronics over time too. Thanks again for testing this Hugo. P.S: at least you now know that one of your chargers is a piece of crap 😂😂😂
A person could attach a Christmas ornament hook to the probe calibration and hang these in a tree while displaying the wave form to Christmas music. They should be used for something after all. I have more than enough mini versions.
Thank you for the review- was looking for a recording 2ch usb scope- (Hantek ??), but saw this super useful hand DSO-152, and then luckily found this DSO-153 review. Have just ordered a DSO-153 on the strength of this video, to work on my cars and bikes (old bikes, new electrical gremlins !) ;)
I am curious about the accessory pack that you had in this video. Mine just came with the alligator clips and the hanging strap. I didn't see a link to the accessories in the description. Do you recommend one in particular?
Hi, in the FNIRSI store you have with or withour accessories and they have the accessories also there. But you can use any generic P6100 probe and a BNC to MCX converter for the probes and a aligator to MCX cable also. Thanks for watching.
Hi, if you don't have issues with it, you don't need to upgrade. If it's not broken, don't fix it 😁 but you can ask in the whatsapp group, they will send you the bin file. Thanks for watching!
Olá Hugo, comprei um modelo igual e reparei que ele que mete algum offset na saída, tal como podes ver ao min 28:43 a forma de onda parece que tem um offset abaixo do zero, sabes me se é uma questão de " é o que é" e pelo preço não se pode esperar mais, ou se há alguma forma de combater isto?
Did you noticed on 152 issue with Single triger, that instrument does not record complete signal, just some 10-20% of signal on left side of screen is captured ?
Just received my DSO153, and thanks to your presentation I almost fully understand it’s functionalities. Very impressive little gadget with a lot of punch. Have a Victor 1025A bench scope, at 25mhz, which I purchased a couple of months ago. I guess for a novice it is sufficient for the time being. What would you recommend for the future when I really get my hands dirty? Hugo, you are doing a swell job, thanks a lot.
Hi, thank you so much for you kind message. If you have the funds €€€ the new Rigol 12bits series is amazing. I'll buy one of those also in the future, it will give you everything you need with quality, siglent also have a new series as alternarive to this. But for a hobbyist, the equipment you have should be enough. Thanks for sharing.
Thank you for the review. During your test, there was the sinusoidal displayed in a rectangular icon by the battery indicator, does that mean that your device was outputting a generated signal locally and measuring from an external device at the same time? Could that be the reason you were getting not very precise results?
Hi, thank you for your support, it can measure ripple from a power source like UPS, you should notice the voltage limits. In terms of amps, you need a special probe for that analysis. I will review a few in a near feature. Thanks for watching.
I would like your advice, because you have a lot of experience with oscilloscopes. I am trying to decide on which 100mhz bench oscilloscope I should purchase(I am still in the learning stage). The one I have has 25mhz and would like to upgrade to 100mhz. Looking at vevor sds1102(same as the Owon, but at a better price), please give me your opinion. Thanks Hugo.
Hi, I received yesterday the CDEK SDS1102 to review, same as the two you mentioned. I will do it in the following weeks, have 2 videos to release yet, but that is the next inline. I have a review of the same model 4 channels and the comparation (showdown) video with FNIRSIS and Hantek, take a look in my older videos. This one seems pretty good, but I have to test it on the workbench to see the accuracy. But you should be ok with it. Thanks for watching.
Hi, I have here the CDEK SDS1102 for review, will have a video in the next couple of days/weeks and it is also a clone of the SDS1102, for the price it seems a very good and complete unit, but after the test will have a better opinion. Thanks for watching.
Just ordered the 1052 yesterday 😔 oh well, will get one of these as well after the first one arrives. Two is better than one 😊 Já agora, excelente canal. Parabéns 👍
Hi, this one is really nice, they added some functions to this cheap oscilloscope that starts to separate it from the really low almost toy oscilloscopes to a more credible one area. Fui ver o teu canal e é fantástico também, eu sou apenas um aficionado e interessado na matéria, a minha formação é na área de IT com administração de sistemas e programação. Mas tem sido uma viagem muito boa, gosto muito de eletrónica e de poder mostrar às pessoas o que podem esperar dos aparelhos antes de os comprarem, isto pode ser um hobby caro e é sempre preferivel ver onde se vai gastar o dinheiro. Obrigado por assistires e pelo teu simpático comentário.
Hi Peoter, there is a new generation of MCU that already have built-in some ADC's that I think these small units are using to achieve these results, they burn the microprocessor so we can't know what is going on there, a pitty! Thanks for watching and commenting.
I have one of these and two DSO-152's. The DSO-153 screen refresh rate is terrible. I can literally watch a line move down the screen as it refreshes. When the signal changes it takes roughly 1/2second to show it on the screen. Anyone else have a bad refresh rate on theirs? Did I get a bad one? My DSO-152s are great.
When I try to use the function generator and the oscilloscope at the same time it doesn't read anything from the function generator. I connected the red cable to the probe and the two black cables toogether...
Hi, thanks for presentation, if you have time to check the low frequencies with your lab devices, kann you test accuracy for signal frequencies between 100Hz - 1000Hz ?
Does the USB-C charging work with a USB-C to USB-C cable? I am asking because some devices are missing two 5.1k resistors, causing them to only work with USB-A to C adapter cables
Hi, I went and test it on another power charger I have here, not only worked with Type-C to Type-C charging cable, but also, seemed a lot more stable in signal that had some interferences with the charger I used while recording the video. Thanks for watching.
Hi, yes much better than the DSO-152, now it starts to enter that club of small oscilloscopes, accessible but with some extra functions also. Thanks for watching.
Hi Scott, several viewers had commented in the past they use this small oscilloscopes also in music instruments and amplifiers, so probably might have some usage for audio analysis. Thanks for watching.
Hi, I don't think that is possible with this oscilloscope. What you're looking is the Zeeweii DSO1511g or DSO2512G, they have AV output. Or you can take a look in the Loto Oscilloscopes, they connect directly to the PC. Thanks for watching.
If you plan to continue evaluating digital oscilloscopes you really need to learn about a phenomenon called 'aliasing'... All those multi megahertz displays you said looked so good were NOT REAL When you looked at the nice 4 Mhz sinewave and the readout on the scope said it was only 1 mhz, it meant that the scope was only sampling at 1/4 the frequency of the 4 Mhz sinewave. Another problem the scope had was vertical 'jitter' that may or may not have been corrected by setting your trigger level to something other than zero...
Hi! The author sometimes forget important things or is distracted, it sucks I know, doesn't make me happy also seeing some mistakes after, but I'll try to improve. Thanks for your comment and for watching!
I like your reviews but not this one. In evaluating the sig gen capabilities you essentially left signal amplitude control uncovered. Sure it can put out Volts. How about 100mV, 200...etc. The amplitude is a very important control. Can I ramp up from 0V passing through Semiconductor Junction thresholds...ie 200 or 600mV. You run the range on frequency and basically don't cover amplitude manipulation ability. Also in the wave forms, did I see a DC level position? Can you control that? Max, Min, increment (looks like 100mV and that's OK. Not complaining because your videos are 95% good. But when something is obviously lacking xI gotta say so. You've done better. Comments 41:06 should help content to improve, that's intent. Keep'em coming
Hi, no worries, please keep commenting. I'll take them always as constructive info to get better, and you're right on your comment. I did left a more precise test on the amplitude. I showed it working, but very briefly. I will try remember in the future to give more attention to it. The granularity of selection on this devide, is somehow limited, but I could covered it better. Thanks for taking the time to write this comment and for watching!
I like all your presentations, very informative. Like your accent. Trying to decide whether to purchase the dso 152 or dso 153. My main language is English, no need to change on selection. Have two function generators. The only advantage I see is the 1ghz bandwidth. Is the 153 really worth it? Could not find a side by side comparison. Thank you for your time.
Hi, in my opinion, the DSO-153 worth the few extra bucks, more bw, more measurements, faster processor and the signal generator is very acceptable, if you have two already is redundant, but overall is a much better device. I would like to thank you kind comment and thank you for sharing and watching!

hi, I did accidentally hold AUTO and it's stuck in the "Awaiting auto-correction" on screen and buttons are disabled. What am I supposed to do now, plug the probe into the 1kHz output or something? It's basically locked now...
is this osc suitable to use for automotive signal troubleshooting / diagnostic use ?

When doing a soundwave test and adustment can this handle 40hz I thing the 152 could only go down to 45 hz?
My DSO153 just arrived- setup and running ok, but frustrating cant seem to find any firmware update for it on FNSRI webpage ??

Sir is it good for ups and amps power testing should i buy it if you suggest me
And if i buy it from description

Noob question. Is it OK for troubleshooting SMD components? I would to build DIY modular synth modules.
Hi, thank you for the demonstration! Is it good for measuring noise from DC SMPS output?
So is there a separate ADC and MPU? Could not see from your teardown
Hi Peoter, there is a new generation of MCU that already have built-in some ADC's that I think these small units are using to achieve these results, they burn the microprocessor so we can't know what is going on there, a pitty! Thanks for watching and commenting.
I am totally new with Oscilloscope, but can you see also waves from 1 to 50 hertz on this Oscilloscope?
Hi, yes you can, with no problem. Thanks for watching.
I have one of these and two DSO-152's. The DSO-153 screen refresh rate is terrible. I can literally watch a line move down the screen as it refreshes. When the signal changes it takes roughly 1/2second to show it on the screen.
Anyone else have a bad refresh rate on theirs?
Did I get a bad one?
My DSO-152s are great.
the scratched IC is very very likely an STM32 microcontroller, they are very common for this application
Hi, agree with you, thanks for watching.
When I try to use the function generator and the oscilloscope at the same time it doesn't read anything from the function generator. I connected the red cable to the probe and the two black cables toogether...
Hi Johny, that's weird. If I remember correctly you can work at the same time. Thanks for watching
Is there a decent manual for it?
Hi, sure there is, I showed in the unboxing. But you have also on FNIRSI support part of their website, the user manuals in PDF. Thanks for watching.
Hi, thanks for presentation, if you have time to check the low frequencies with your lab devices, kann you test accuracy for signal frequencies between 100Hz - 1000Hz ?
I notice the ripples when charging while using ??
Hi, yeah, it was a bit of noise, I think the power supply is ready for the garbage bin.... thanks for watching!

I probably will buy one, it's a cool toy. But, hoping level is adjustable.
Hi, yes much better than the DSO-152, now it starts to enter that club of small oscilloscopes, accessible but with some extra functions also. Thanks for watching.
Something like this might be useful to audiofiles
Hi Scott, several viewers had commented in the past they use this small oscilloscopes also in music instruments and amplifiers, so probably might have some usage for audio analysis. Thanks for watching.
Great video!
Good video! Thanks! Fnirsi secretly support for Ukraine V1 + V2 )))
Hi, ahaha good one! thanks for watching.
Only one thing missing - ability to record/save waveforms ???
Hi, totally agree. Thanks for watching.
Giúp tôi cách kết nối để hiển thị nó lên laptop dễ quan sát, cảm ơn

Why did the author test 500kHz on 10x? I think it would be less precise than 1x. He has only 1vvp, so it wasn't any reason to do that.
Hi! The author sometimes forget important things or is distracted, it sucks I know, doesn't make me happy also seeing some mistakes after, but I'll try to improve. Thanks for your comment and for watching!
20:37 I'm have look at spec , bandwidth of the little guy is 1MHz , 4 MHz is too much :D

Hi, it starts to be embarissing now! 😬 Thanks for watching and your nice comment 😁
Poor performance from device. I Could not measure 3.7 Vdc from bench power supply. Also, the unit freezes when selecting auto function.
Anyone considering this.. get the 154pro instead. A much better device
