    I bought this scope last year. I love it. Used it many times for making repairs.

      Hi, great to hear! It has some bandwidth limitations considering the announced, but I was quite suprised by the sensibility in voltage detection, pretty neat! I think is a nice tool. Thanks for watching 👍

      Hi Khuong. Glad you liked it! This friday we have the KKMoon DSO120M... but what I'm really excited is with the SigPeak that will go online on 18/08 😁😎 Thanks for watching! 👍

    Tem um detalhe que revi o vídeo e notei que vc mediu alta frequência na escala de 1x. Se tivesse em 10x seria diferente. Pelo que vi o 1c15 conseguiu lê 50mhz em 1x e o 1511g não. Coitado do 1c15, sofreu ao ler aquelas frequências altas, que na verdade deveria ser em x10. Depois de ter revisto o vídeo novamente, fiquei na dúvida qual seria o melhor. O 1c15 ou o 1511g. Obs: lembre que no vídeo do dso1511g, vc estava medindo a alta frequência em X1 e ele não estava conseguindo medir e vc acabou corrigindo, mas 1c15 vc não fez o mesmo. 😢

      Olá Marcelo, a sério? Vou ter de ver o vídeo para perceber onde falhei. Mas em qq dos casos o 1C15p é um bom osciloscópio. Obrigado por assistires.

    Please measure the rise time of an square wave (and show the picture).
    This is a very important parameter.

    • @TechCornerTV
      @TechCornerTV  2 года назад

      Hi Paul,. I'm not using the rise time method, even if I know what you mean because 2 main reasons:
      1) it is very hard to do honest test on this small handheld oscilloscopes, because is very hard to find out the upper and lower 10%, we don't have cursors. making it even more difficult.
      2) Those oscilloscopes are supposedly 100Mhz, so I need a signal generator that can have a rise time of lesser than 1ns, I don't yet. So, to be accurate and fair, I preffer for the moment not do that test.
      Even so, for all I know and I always open to the option that I'm wrong, but with 1Vpp, the -3dB point is at around 707mV maximum, so we kind of know what is the maximum bandwidth because if it goes under that you reached the maximum frequency. Thanks for watching 👍

    Qual é o melhor, 1c15 ou dso1511?

    • @TechCornerTV
      @TechCornerTV  2 года назад +3

      Olá Marcelo, na minha opinião e de acordo com o que percebi pelas reviews que fiz, o DSO1511, de longe. O unico problema que vi nele (além da banda não ser realmente de 120Mhz) é mesmo não teres suporte. Porque em termos de máquina, é melhor. Obrigado por assistires 👍

    Very nice review. Thanks! Your review confirms that this is one of the better handheld scopes that I've come across.
    I like the concept of these scopes, but I constantly want them to either get a bit better or a bit cheaper. I think this model should cost $45 at this accuracy and bandwidth *or* that it should have much better sampling accuracy at a true 100MHz for $64. Even still, it's not terrible and can show a reasonable waveform at lower bandwidths. They should focus on improving the accuracy and stability at a properly rated bandwidth and sampling rate instead of exaggerating and interpolating so much.

      Hello Rob, last night I recorder the video that will available next friday and as a spoiler alert, there is competition in the horyzon 😎 but that didn't take credit from this little fellow. Not counting the BW issue, it is a pretty decent oscilloscope for the price. You're right, some more tune up will ve good, but if see the signal of the DSO2000 from hantek, the signal also have a lot of jittery and is a 4 or 5 times more expensive equipment, not a excuse, but it is what it is in this market. Thanks for watching 👍

      Hi Paul, unfortunatelly is a market malpractive for every low cost brand, it's sad, because if they anounced a 30 to 50Mhz oscilloscope, the review will be awesome product. But I still mantain, that is a nice product anyway, but kinda fill ripoff. I just found out that my 150HP car has 75HP engine.... it's a nice car anyway, good seats, nice electronics.... nut will not go up to 220Km/h... but it will work ok up to 160km/h... that's the feeling 😁thanks for watching! 👍

    A nice thing to write about the manufacturer is that they stopped wasting time by erasing the part numbers from the IC's.

      Hi Paul, never got why they will do that... well, on a second though, probably so the users won't find out that the parts can't perform with the announced specs... 😎thanks for watching! 👍

      Hi Paul, because people buy the products anyway and that why I do these videos, you may decide to buy anyway, but at least you know what you're buying and you decide in good conscience. This is a nice product, just isn't a 100Mhz bandwidth oscilloscope. The all point of this channel is show to the viewers every detail of the equipment so everyone can decide before buying, if even with the problems it comes with the equipment will be a good product to buy. of course that the ideal is to have the correct specs in the decice, so we know what we are buying. Thanks for watching! 👍
