    HEY YOU ABOUT TO POST SOMETHING STUPID:
    Yes, I know my hands are large/fat. It's because of a heart condition I suffer from called Congestive Heart Failure. Here's a link to some information about CHF: cle.clinic/2TdS2Ux
    One of the symptoms is that is causes fluid retention, mostly in the hands, feet/ankles, and face.
    It will kill me one day. I'm doing ok right now, but someday...

      The Aneg 8008 is a great little meter very accurate, can't better it for under £50 & it's only £16. ! It's also better than the new one they just released.

    That was measured in Chinese Mhz. Very similar to Chinese watts PMPO watts on amplifiers. I bought one as was curious and pretty much reversed engineer one recently. The 500MSPs they claim is a straight up lie - there's no way that the 250MHz GD32F450 can read two interleaved samples every clock cycle nor could it generate a 250MHz clock. It is about 250MSPs. Even then no way to get 100% reliable triggering at 250 MSPS. There is just no enough processing power in this and is the bottle neck. With the current design and components used 125 MSPs is likely all it can do reliable. So Dave review is pretty much bang on, this thing has serious trigger issues as they are doing it at the buffer.
    No hardware trigger, it's all done by the software. They claim on eBay and Banggood it was using a IPS screen and 5000 mAh battery, still see listing stating that. Neither are true. It uses a TFT LCD and 3000 mAh battery. The official store is at least now being honest about that part. Some less then honest vendors "forget" to update the description.
    So yes as I am stating it is a 125MSPS and not the 500 MSPs as they claim. So about 22 Mhz, but in testing was able to only trigger at about 10Mhz reliably The front-end is also lacking at best.
    Main components on the board:
    GD32F407VET6 - MCU (Cortex-M4, 512 KB Flash, 192 KB SRAM)
    AD9288 (probably a clone, no markings) - ADC
    TP4056 - Li-lon Battery Charger
    TLV70033DDCR - 3.3 V LDO
    PC817 - Photocoupler
    CPC1002N - Optically coupled solid state relay
    . The one on this video is different as his is using regular relays?
    SN74HC148 - 8-line to 3-line priority encoder
    SS8550 - PNP transistor
    HFD4 - Mechanical relay
    OPA356 - 200 MHz, CMOS OpAmp
    W25Q64JV - 64 Mbit SPI Flash
    TFT Display - Based on ST7789
    200MHz OPA356 amp

    I ordered one within a day of your review. It came in two days ago (27 Aug), but required a signature, so I had to make a 10 mile trip into town. Nice compact unit. Outer box was crushed along one edge, but the 'scope comes inside it's own travel case which prevented any damage. English instruction manual is fairly well written, far better than some that come with other electronic products. Thanks Paul.

    Did you see which ADC is used in this oscilloscope? It should have some buffer for storing 500ms/s?, defenetly it can not be done with 168Mhz CPU. If it doesn't have some additional HW except display driver and CPU, so how it sample the data at 500MS/s?

  • @stevedonovan9265

    An obvious shortcoming with the cheapo scopes is they can't display a proper signal beyond a low range. You didn't feel it necessary to use a capable generator to test even one one hundredth of its stated capacity?

    • @InXLsisDeo
      @InXLsisDeo Před 4 lety +1

      They state 500 Msamples/sec which would translate to 50-100MHz range, but yes he should have checked that claim because it's the most important one. He could also have checked whether the peak to peak tension measured goes down with frequency, meaning it's not so reliable. 10% off is quite big a difference.

    We have to be careful with Banggood. They don't refund the full purchase price if the good is defective. From recent experience, they refunded me $45 out of $68 for a defective power supply I received. On top of it, they prevent me from doing a review! Buying expensive stuff is a bit risky.

    The scope is isolated but the BNC connector on that probe is metal, so if you have a potential to ground on the scope's ground clip (like connecting the ground clip to the hot side of the mains) that collar will zap the poopie out of you.

This seems like a good option though, probably a lot better than the latest batch of £40-£50 scope multimeters and definitely better than a £20 Chinesium kit.

  • @ptarsob
    @ptarsob Před 4 lety +1

    What really matters is the minimum rise time measurement of a square wave, a fast rise time is obviously related to the BW.
    A good 100 MHZ oscilloscope would show its rise time of 10 nS.
    A very fast rise time ( like 1nS) 1 KHz square wave generator is the best signal to evaluate an 100 MHz oscilloscope.
    Not a sine wave.

      @@andymouse This is my first Oscilloscope and to be honest, it does far more than I will ever need a scope to do. They come fully unlocked these days too, so all the functionality is there from day one! There are many reviews of this scope on here and they all seem to love it, so if you are in a position to buy one then you will not be disappointed. I remember from my younger days using an Oscilloscope and it was huge and heavy, but the Rigol is lightweight and has every feature under the sun. Even though it is a few years old, it is still one of the best Oscilloscopes on the market. Look up some reviews on here and see what you think before you buy. Best of luck.

    Hate to say this, but i was only able to use mine twice before it started displaying an vertical offset. Waveforms get cutoff at the bottom as well. Not sure why this happened because I was merely using the scope to measure 5V DC transitions from a MCU. Worked great before all this happened. The calibration also failed...which was what i read was supposed to fix the offset issue.

    I am seeing this and remembering the Velleman HPS10, which I had bought in 2003 and which eventually went out in the trash, due to it developing a completely black screen, and the LCD no longer being manufactured. Surprisingly, Velleman up to recently was still selling hand held scopes with the same screen resolution and specs as the HPS10 (1 MHZ analog bandwidth, 128x64 monochrome LCD) , at twice the price of this product! Who is buying them?

    Hello folks.
    I have already tested this little toy for it's true analog bandwidth.
    After few attempts with few arbitrary waveform generators,I have got a result of 35 Mhz true analog bandwidth.
    When,at the rest of the declared bandwidth it can be used as waveform reader or waveform exhibitor if you wish. 🤷‍♂️

      ​@@thetechgenie7374 Since then, I bought it (in fact I bought it slightly before Dave's review but it took a couple of weeks to receive it from China) and it can go up to about 30MHz in sine mode without excessive distortion (aka peak to peak values are correct to within 5-10%), and then it degrades in value above that. As for square wave, from memory it's okay up to 5 MHz. This is good enough for many hobbyist's projects. For me its biggest weakness is the fact that it cannot be software upgraded and the software isn't open source. Else it would have been much improved already. So it's really a mixed bag, but at this price point there is definitely no competition. If they released a v2 that addresses most of the feedback (properly engineered front end, upgradable and open source firmware), it would be a killer. It's really a shame, because they were 90% there.
      edit: the most in depth review evaluates it to ~40MHz for sine waves at -3dB, which is consistent with my evaluation.

      ​@@InXLsisDeo That was measured in Chinese Mhz. Very similar to Chinese watts PMPO watts on amplifiers. I bought one as was curious and pretty much reversed engineer one recently and going to do a video on it. The 500MSPs they claim is a straight up lie - there's no way that the 250MHz GD32F450 can read two interleaved samples every clock cycle nor could it generate a 250MHz clock. It is about 250MSPs. Even then no way to get 100% reliable triggering at 250 MSPS. There is just no enough processing power in this and is the bottle neck. With the current design and components used 125 MSPs is likely all it can do reliable. So Dave review is pretty much bang on, this thing has serious trigger issues as they are doing it at the buffer.
      No hardware trigger, it's all done by the software. They claim on eBay and Banggood it was using a IPS screen and 5000 mAh battery, still see listing stating that. Neither are true. It uses a TFT LCD and 3000 mAh battery. The official store is at least now being honest about that part. Some less then honest vendors "forget" to update the description.
      So yes as I am stating it is a 125MSPS and not the 500 MSPs as they claim. So about 22 Mhz, but in testing was able to only trigger at about 10Mhz reliably The front-end is also lacking at best.
      Main components on the board:
      GD32F407VET6 - MCU (Cortex-M4, 512 KB Flash, 192 KB SRAM)
      AD9288 (probably a clone, no markings) - ADC
      TP4056 - Li-lon Battery Charger
      TLV70033DDCR - 3.3 V LDO
      PC817 - Photocoupler
      CPC1002N - Optically coupled solid state relay
      . The one on this video is different as his is using regular relays?
      SN74HC148 - 8-line to 3-line priority encoder
      SS8550 - PNP transistor
      HFD4 - Mechanical relay
      OPA356 - 200 MHz, CMOS OpAmp
      W25Q64JV - 64 Mbit SPI Flash
      TFT Display - Based on ST7789
