Great scope once working, not so great right out of the box.
4 out of 5 stars
Great scope once working, not so great right out of the box.
This oscilloscope was a little tricky out of the box. Firstly, the included power supply was of the 2 prong variety, but this was expected as mentioned and photographed. The manual prohibits using other power supplies, but I found no issue with a high-quality mobile phone charger.I also ran into (and overcome) two further issues out of the box. Firstly, I was unable to get the trigger function to work reliably, but this was resolved by updating to the latest 'FNIRSI' firmware (this is a rebadged FNIRSI 1014d). The second trouble I had was that channel 1 was reading far too low on the 1V scale, this was caused by a sticky relay, and rapidly switching the voltage div knob fixed that. (See photo for the wave)It is great that this oscilloscope can operate from an isolated 5v supply, it makes measurements of signals that reference a non-earth potential possible, though a little dangerous. The integrated function generator is nice to have, it would be even better if it had a level control for it, as it is a 5V signal.
Thank you for your feedback

    I’m still dubious about support: I’m pretty sure this is a re-badged FNIRSI model, but I can find no web-presence for Yeapook (downloadable user guides/firmware updates if needed). At the price I think it’s hard to beat. Annoyingly, it came with a Chinese power adapter (easily fixed - it needs a typical, isolated, 2A+ USB supply). After reading a number of reviews (mostly FNIRSI) I gave it a quick checkout. It’s not the most accurate - less so as you get towards 100MHz (but a 100MHz scope only reproduces sinusoid fundamentals near the limit, so you can’t expect it to recreate a 100MHz square wave). I was also worried about reports of wildly inaccurate measurements, but so far it looks quite good (just make sure the probe info is set up properly, and that you aren’t using too slow a timebase and actually looking at an ‘aliased’ signal reconstruction). I do find CH1 seems to have a little inbuilt overshoot (after adjusting the probe). For the price I have an extremely good, hobbyists diagnostic tool with a useful signal generator (& - unless I can find a way to extract/analyse the data - pretty pointless FFT analysis)

    I have given this a five-star review because I am more pleased with it than I expected to be.

    To have a quick look at what it could do I plugged it in straight out of the box (using a wall-socket USB which can supply 2.1A at 5V). I then pressed the green signal-generator button and set up a 500Hz square wave (using the various navigation arrows plus OK). I then hooked one of the probes to the signal output (using the supplied signal output lead), pressed the auto button and there was the square wave on the screen. I then just played around with it to familiarise myself with the controls. You can always just unplug the leads and factory reset the whole thing via the menu button.

    My main worry was that some previous reviews have mentioned various bugs that needed fixing by updating the firmware for the FNIRSI 1014D (which is what this device clearly is). However, when I looked for those bugs, they didn’t seem to be present. For example, a review on the famous video site said that you couldn’t switch between AC and DC coupling on one of the channels without the update– you can on mine. I assume that the ‘scope I have was shipped (February 2022) with the latest firmware updates, which is why I am more pleased than I expected.

    In the box you get exactly the same manual that you can download from FNIRSI (with just the name changed). Whoever wrote the manual probably does not have English as their first language, but, having said that, it’s not bad – they obviously know what they are talking about. Just heed the ‘Serious Warning’ so that you don’t destroy your ‘scope. Other than that, everything becomes clear when you experiment with the machine. The manual is certainly not exhaustive. You will have to figure out all sorts of things by common sense and experiment (for example, the voltage values on the horizontal cursers give the voltage difference between the cursers, and so on). There is also a leaflet with the probes (and a bag of bits including screwdriver) that explains how to compensate the probes. I did that and it works easily.

    If you are new to oscilloscopes, like me, I would recommend a read of something like ‘XYZs of Oscilloscopes ‘, free to download from Tektronix and/or have a look at some videos. Pricewise, apparently it’s a bargain compared to other ‘scopes. For me, for occasional hobby use, it’s a bit of chunk of money. On the other hand, it does cost less than two tanks of fuel.

    I was unsure about ordering due to some of the UK reviews saying that the power adaptor was low quality. The one I received didn’t have any UK adaptor at all - just a USA one. However, all it needs is a 2Amp USB A power supply! That aside, it looks like a quality bit of kit for the price with decent probes. I was particularly impressed with the screen quality and menu system. So far I have tested on basic sine waves and PWM motor controllers and it looks accurate enough for hobby use. Very impressed for the price!

    For the price, the scope is one the best options for hobby electronics and those who like to tinker with electronics. I was a bit apprehensive about the quality based on some reviews I saw and read, but I was quite happy with what I got. If you don't expect this to operate like something that is twice the cost, it does more than what is expected. It has a nice simple interface, ability to save pictures and waves, generate a good set of signals and comes with everything you need to get started, including two 1-10X probes, crocodile clips, USB-to-USB cable and a UK power adapter, . It operates on 5V 2A USB power supply so it is portable if you have a power bank. External build quality is decent, screen is very clear. There is a bit of a noise you can observe with nothing connected but I would put this down to interference from internal wave generation circuit and this does not affect the measurement if you are not going to use it for highly precise applications - in which case you would be better off with high spec scope. I have used this to test some signals in a switching power supply (secondary only), TV mainboard signals and some small Arduino projects and was good enough for the price.

    In summary, there are few drawbacks but this a good scope for hobbyists and use in simple repair work for most household electronic circuits.

    Initial measurement displays were showing voltage spikes that seemed to be from the switch mode power supply that cleared when using a power bank. After using this oscilloscope for some time, the problem when using the SMPS seems to have resolved itself and is ok now.

    Seems to meet the specification in full. As a dual trace oscilloscope it works extremely well, and the Auto button saves a lot of setting-up time. The signal generator has the most amazing range of waveforms and can copy a trace or part of a trace. The FFT function translates into frequency domain, although the trace isn't expandable.

    On the down side, given the price it's not surprising that the controls are multi-functional and take a little getting used to. The power pack wouldn't plug into a universal adaptor and so I used a phone charger instead.

    All-in-all, I've very satisfied with my purchase so far.

    5.0 out of 5 stars If you need a basic oscilloscope at a budget price, then this is an excellent choice.
    Reviewed in the United States on 19 July 2022
    General: I have had my scope for several days, and I am quite pleased with its performance and ease of use. It has a large display, making it easy to read. I find the user interface to be intuitive to anyone who has used a scope before. Even a first-time user should not have too much difficulty in figuring out the controls. I consider the built-in signal generator a plus overall. The user's manual gives a very brief description for each control. The one real down-check is the user's manual; it is really small and would benefit from written examples of typical usage.

    Specific: The question a person should have in mind is: How am I planning to use an oscilloscope? I am an electronic hobbyist; I tinker around with amateur radio circuits, building test jigs, and playing with RF filters in the lower HF range - mostly 40 and 20 meters, and occasionally troubleshoot a broken radio. I've used more fully featured (and more expensive!) scopes before, but I am finding that this scope covers 98% of all the typical tasks and troubleshooting that I do. When something falls into that 2% range, I visit a friend that has a better scope.

    Conclusion: This is an entry-level, hobbyist scope with a reasonable bandwidth. It takes up very little space on my work table, and while the signal generator is limited, it does serve its purpose. Only time will tell on how well this scope lasts. It's a lot of bang for the buck, so if your needs are anything like mine, I don't see how you can go wrong.

    Das Teil ist pima!

    Gerät wurde wie beschrieben geliefet. Stromversorgung über Steckernetzgerät 5V 2A über USB-A auf Rundstecker... somit einfach über Powerbank zu betreiben.
    Ein Kollege von mir hat Probleme mit der mitgelieferten Stromversorgung. Diese macht starke Störung und auf der Sinuskurve gut zu sehen. Mit Powerbank ist dieses Störung weg. Da hab ich wohl Glück gehabt. habe diese Problem nicht. Gut und einfaches Gerät mit kleinem Frequenzgenrator dabei.
    Beim Frequenzgenerator kann man die Frequenz nur z.B. 50Hz 51Hz 30Hz aber nicht auf 50,3Hz oder 50,1Hz einstellen (zehntel Stellen) Oder ich habe die Einstellung (Step?) nicht gefunden. Man kann nicht alles haben

    Ottimo prodotto. Si tratta di un FNIRSI rimarchiato. Pertanto si può effettuare un upgrade del firmware dal sito FNIRSI.
    Il prodotto è economico ma perfettamente funzionante.
    Interessante la possibilità di alimentarlo con un powerbank e quindi, oltre a essere isolato dalla rete, potrebbe essere utilizzato in zone done non è presente l' alimentazione.
    Le sonde sono un po' economiche.
    Dispone di un generatore di varie forme d' onda.
