Olá Daniel, muito obrigado pelo comentário, no geral gostei, acho que esforçaram por introduzir mais funcionalidades, só aqueles 3 pontos é que poderiam ser melhorados. Abraço!
Fabulous review. Interesting that the sig gen is ON all the time. Tried to get the custom startup screen working, but no file type or size would work. (no biggie)
Hi, agree with you. With one or other rush to the market issues, but overall they're in a very consistent way taking the lead in their market segment. Thanks for watching and commenting.
It should provide a frequency sweep of at least 20Hz to 22KHz for the signal generator. Then, it can be used for amplifier and speaker tests. I think a firmware update in the future would make this possible. So, the FNIRSI should consider this.
Thanks so much for you great reviews! Been looking at the FNIRSI 2C53T since it was released. I have also been looking a the Zoyi ZT703S. These DSO's would be my secondary scopes. I have the Siglent SDS 1202-E as my main scope. What would be your pick between these portable DSO's?
I think this is the best 3x1 from chinese market now. The alternative would zoyi zt703, but it has serious problems near 47Mhz. Some bug fixing on 2c53t can make it the best in this category.
Hi, agree! Some tweaks here and there and will bring this to a very nice position in relation to the competition. Zoyi is a really nice device also. Thanks for watching and commenting!
I think the Zeeweii DSO 3D12 is the better choice. Have you had a good look at it? It is a bit more expensive, but I think the way better scope is worth it.
It would be interesting to see a teardown of the 2C53T compare to the 2C23T and a look inside of the dso510 to see if the function generator share the same components, because the firmware version are not that far apart dso510 V1.0.1 and the 2C25T V1.0.5.
Hi, I want to do an oscilloscope showdown with all these devices, but I have to limit it to 3 or 4, otherwise it will be too long... thanks for watching and your comment
@@TechCornerTV if you do a test please test how fast are when switching frequency of the test. like from 3Mhz to 7Mhz. As I observed you have to use Auto to show something relevant. Probably a decent scope its able to adapt to the new frequency automatically. And that digital square signal is most important cause you might wanna use it to debug an ESC or an invertor.
Did you notice that for the lower mV readings, the display was showing more decimal places than the meter was able to read? - so, for example, in the 1-10mV range, there was only 1 decimal place active, so the last 3 decimal places just read a constant 000. This is pretty mis-leading - the number of digits displaying should match the sensitivity of the reading.
Hi, the DSO3D12 is a different beast, I like it very much and has much higher bandwidth and Zeeweii normally comply with the specs. FNIRSI is doing great equipments like this one and the predecessor, personally I like more this format, but for a desktop usage the DSO3D12 is a really nice device. To be honest, it comes down to your personal preference. It's like comparing a Peugeot with a Renault. Both have strong points for their range. Thanks for watching and commenting.
Hi, and thanks for your great review. I have just purchased one of these units and I'm generally pretty happy with it, except for one thing - for some reason, the AUTO trigger function button will not stabilize a waveform that is of lower frequency than 1kHz - For signals over 1kHz, the AUTO function works well, but below that, it seems to just take the time base down to 10 or 20nsec and then it just gives up - it won't try to move up the time base to milliseconds.. The waveform stabilizes if I manually change the time base to milliseconds with the left arrow button. I'm not sure if I have a setting wrong somewhere or if the unit is faulty. Could you test this on your unit for me and let me know if you think I have a faulty unit or if this is normal? Many thanks
Also, sometimes when I hit the AUTO button, the whole unit locks up with the screen showing the "Awaiting Auto Correction" flag on the screen - none of the buttons respond at this stage and I need to do a hard reset to get out of it.
Also ich sende meines wieder zurück, es ist der größte Billigschrott, es hängt sich ständig auf, das Display ist kompletter Müll so grob und ungenau, das man nichts damit richtig messen kann, die groben Pixel geht im Jahr 2024 überhaupt nicht so. Die teilweise so kleine Schrift in blau ist für Brillenträger unleserlich. Das Modell 2C23T ist an den Stellen viel besser ablesbar. Das Beste an der Lieferung ist die tolle Tasche, vielleicht kann ich darin mein Amateurfunk drin transportieren.. Nachtrag: Es friert weiter Ständig ein, in so einem komischen Kalibrierungsmodus. Habe das Problem den Support mitgeteilt, der meine nur, das ich den Reset Knopf drücken soll. Wenn die nicht mit einem Firmware Update fixen, dann wird PayPal das Gerät zurück wandeln..
Hi, in terms of quality, they're are equally good. In a personal preference, I might prefer the 2C53T interface, but again in terms of accuracy, performance, etc., Zoyi ZT703S is also an excellent choice. I think it resumes to your preference in terms of features and UI. Is a bit comparing Rigol and Siglent devices... Thanks for watching and commenting.
Хороший любительский аппарат, но зачастую нужно измерять несколько параметров и еще питать всё это от генератора. Поэтому по старинке предпочитаю дискретные приборы в пучке проводов
This November 2024, I got a DPOX180H. Nice oscilloscope but... Too many bugs :( There is not support. 1)there are 400mV dc offset in signal generator 2) trimmer adjust on probes lose adjust when I select AC / DC mode. 3) measures Vpp, Vp rms. Not accurate. Even it shown 200% real value when v/div is changed. If I ignore signal generator, and numerical voltage values on screen... This device worth well. Fnirsi = FbugNirsi
Hi, your comment is totally aligned with my idea on this, if ignore the gauge, the fonts and the huge downgrade on the function generator, this will be a awesome multimeter + oscilloscope. Tanks for watching and commenting.
Multimeters should be stress tested more. At least accidentally touching line voltage in resistance mode. I recently broke one of my Chinese dmm/osz device with this simple mistake. Blew two transistors. The protection in these cheap things is quite rudimentary.
Hi, well I try to test all functions with a minimum effort, even so the video is really near to 1 hour... yaks! but I will take in consideration in future videos. Thanks for watching and commenting.
Fala meu amigo. Esse realmente eu gostei muito. Ficou meu 3x1 favorito. ValeU!

@@TechCornerTV é, para novos produtos não se deve fazer um downgrade de funcionalidades.
Thank you for the detailed overview with tests! I think, the scale 1-20 just shows where are you at the 20k counts range.
Hi, thank you for sharing and your nice comment
Fabulous review. Interesting that the sig gen is ON all the time. Tried to get the custom startup screen working, but no file type or size would work. (no biggie)
Hi, for the startup, normally is an uncompressed BMP. Thanks for watching and your nice comment!

HI, I did not enter the amplifier construction/testing yet, but it is nice to have this info. Thanks for watching and your comment.
If I buy the 2c53t will I be able to calibrate this tool’s oscilloscope and multimeter function manually? Or is it done automatically via update?
Thanks so much for you great reviews! Been looking at the FNIRSI 2C53T since it was released. I have also been looking a the Zoyi ZT703S. These DSO's would be my secondary scopes. I have the Siglent SDS 1202-E as my main scope. What would be your pick between these portable DSO's?
For the FNIRSI models, does the signal generator voltage oscillate between positive and negative voltage?

@@uni-byte I'm contemplating to buy either 2 of these products but now you've introduced a new challenger so i got to check this one.
If you compare the osilloscop layout and the setup menu layout you will see that it looks similar to The fnirsi DSO510.
Hi, you're right! Thanks for watching and commenting.

where is the digital square wave oscilloscope test? I want to know if its better than a ZT703S.
