Hanmatek DOS1102 Digital oscilloscope with 2 Channels and Screen 7 inch / 18 cm, TFT-LCD Display, Portable Professional Oscilloscope Kit with 110mhz Bandwidth 1GS/s Sampling Rate

After a weeks wait was great to finally get my hands on my New Hanmatek scope, after unpacking the scope and the probes I came across the lead supplied by Hanmatek for it to be used in the UK. Under no circumstances use this lead it's a fake UK adapter, and information has been passed on the relative authorities, the lead says 10A on it, and its not fused the sleave for the earth pin is partly shrouded, therfore ommiting contact if it was inserted into a UK 3 pin socket, as its not fused, only protection is from the 32A main, and that won't trip due to the earth pin not connecting to ground at all. The manual says max 3A and I've had to order from Amazon a genuine kettle lead as the Brits call them. I've relayed my worries a cross to Hanmatek and been fobbed off,they don't seem to be bothered about the dangers of their fake UK plug, leads. Anyway the scope is beautiful easy to set up and has function for self calibrate once the scope has acclimatised to its surroundings, readings are clear, the math button is a cool feature for FFT. I have a anologue 20 Meg scope 2 channel, and the new Hanmatek scope is a great addition to my bench, its light weight, and very slim, so if you don't have a lot of space on your bench the scope is well suited for small bench setups, it's very quiet, only noise you can hear are from the relays ki King in when you Auto setup the scope. Screen is very clear and with all the added functions incorporated in this scope, it sits with, and may surpass even higher Scopes imo, All in all great buy, but if your from UK the lead needs changing do not use its unsafe, and not worth your life if you use it. Amazon needs to address this issue. As someone that's not ever bought a scope and want one as a first scope, it's brilliant, but please DO NOT USE THIS LEAD SUPPLIED.

My old CRT Scope exploded spectacularly and I needed something modern to replace it. This little gem fitted the bill perfectly, and was a much better spec as well as being about a quarter of the size ;) The 110MHz Bandwidth is more than adequate for repairing your basic retro-items like old Commodore or Spectrum Computers and the sampling and storage facilities will definitely help when it comes to diagnosing timings. The results can be saved to USB so sharing that information on your favourite forum is a breeze. As for the basic operations, as soon as you turn it on, following a splash-screen, you are taken straight to the main scope display. It comes with two well-made probes, both with a x1/x10 switchable function and the menu on the scope allows you to accurately select which probe you are using so that the resulting waveform will be correct. Adjusting the x10 probe compensation is a breeze but you will need a non-metallic adjustment tool... anybody who does radio work will understand why ;) At first I was confused at how to adjust the frequency display but turning the "scale" knob sort that one out, and if you can get your head around adding functions to the display then you can have the frequency displayed on-screen... which is really useful when playing with clock timings on retro computers ;) Trigger levels can be adjusted for rising / falling edge and selecting which channel to be used as a trigger is a simple menu function. Turning channels on and off requires a couple of presses of the channel select button but no biggie there. Over all this is a nice little entry-level scope and well worth the money for anybody who is thinking of buying a nice basic "gets the job done" scope for their workshop or who are first starting out using an oscilloscope. Working your way around the menus takes some patience and at times does not seem to be an intuitive process but sticking with the manual and experimenting will get you there, it isn't difficult... just not exactly as you would expect a menu to work. That apart, this is a lovely little scope and I would highly recommend it to both first-time users and to anybody who just needs a basic 110MHz bandwidth scope to do basic signal tracing and sampling, and if you are into repairing those retro items then this scope will be just perfect for you, and will take up almost no room on your bench. The 5v Power Supply will also cut down the cost on your electric bill as well ;) Highly recommend, go for it, treat yourself ;)

Very impressed with the features, the leads look good quality & for the price, it's a no brainer. the down side: the trace is a bit noisy, & less than 100% accurate, but for audio fault finding & setup it's good enough

Decent oscilloscope for the price. USB power supply it is very handy, it's not heavy, it is mobile which is good. The test probes are okay. Still working well after few years of occasionaly use. I didn't tested/used the max frequency, I went maybe up to 20MHz. When I need an oscilloscope I have one ready to use.

It's as good as my trusty old 40MHz analogue 'scope, with the added advantage of additional maths functions. The menu structure is logical, and whilst not as convenient as the 'knob a function' of the old 'scope, it does make for a less cluttered control panel. Vertical and horizontal display accuracy is good, but I question the accuracy of the RMS voltage measurement as it over indicates. e.g 775mV @1kHz as measured on my audio millivoltmeter will indicate something like 850mV. Triggering is very good, and has split triggering so both traces will trigger even if they're of different frequencies. Overall, a very useful instrument, at a decent price.

Won't give a rating yet haven't used it. But I will be back when I have.

Great size, clear screen. Enough buttons, knobs control to feel like Lab equipment. Planning raspberry pi projects and from initial tests looks more than up for the job. Good value I feel, sturdy product and feels well put together.

OWON SDS210SのOEM版のようです。仕様の違いは、ストレージ容量が10Kポイントに制限されること、電源がUSBになること、まだ試していませんがPCとの連動(Labview)に制約があるようです。日本で手に入る価格ではこちらの方が1万円以上安く、シグナルジェネレータ付き、USB電源はバッテリー駆動も可能でメリット、ホビー用には帯域も十分以上です。欲を言えば、サンプリングレートを表示できるようにしてほしいですが、ソフトアップデートに期待して星５つです。 機会があれば本家OWONも入手して、どちらがより私のニーズに合うか比較してみたいと考えています。

Je suis électronicien retraité depuis longtemps, j'ai acheté cet appareil juste pour m'initier aux technologies numériques vis à vis des oscilloscope analogiques que j'ai utilisés toute ma carrière Mon avis ne concernera donc pas les performances limites de l'appareil mais juste son fonctionnement général qui correspond parfaitement à ce qui est promis tant sur sa description sur le site que dans la notice d'utilisation A mon avis pour une utilisation de base il en fait tout autant que les appareils plus chers, donc très bon rapport qualité prix Points positifs particuliers l'écran plutôt grand de 7 pouces, les traces bien lumineuses, les commandes réparties de manière très claires ( même si assez spéciale selon certaines critiques ) Points négatifs l'entrée du cordon secteur sur le flan,l'absence d'une entrée pour synchro externe, la notice limitée à la prise en main et uniquement en anglais mais toutefois disponible en français sur le CD d'installation Au moment de l'achat j'avais envisagé l'oscillo Omron 1102 quasi-semblable sinon identique mais plus cher. On trouve facilement sur le net la notice de ce dernier, or elle reprend d'abord la même notice rapide que le Hanmatek mais on y trouve ensuite un guide d'utilisation avancée très intéressant et qui s'applique parfaitement au Hanmatek

Love this thing, bought it as my first proper oscilloscope and it's been working very well so far. Very useful for electronics hobbyists, and this version with the signal generator was worth the extra 10 bucks vs the base version (plus i think it looks extra cool in black). Does everything I need it to, and was simple enough to figure out just by messing around with it and watching a basic guide to oscilloscopes on YouTube. One thing I think is very cool is how it's powered, it comes with a usb to barrel jack power cord with a little power adapter that plugs into the wall, so you can do that or just use a simple power bank to power it, which id say makes it a lot more portable (and you don't have to worry about accidentally shorting it to ground if you try to probe your mains wires). Overall, very well rounded device, and a must have for those who want to enrich their understanding of electricity by visualizing it

Ottimo strumento con un rapporto qualità e prezzo indiscutibile. Molto apprezzato il menù in italiano
