HANMATEK 110mhz Bandwidth DOS1102 Digital Oscilloscope with 2 Channels and Screen 7 inch / 18 cm, TFT-LCD Display, Portable Professional Oscilloscope Kit with 500 MS/s *2 Sampling Rate

My old O'scope is a Hameg 20 MHz dual-trace I bought in (then West) Germany in 1982 for about $2,000. It's heavy, has a tiny CRT and dual-trace, but I've lugged this thing around for 42 years and now it's almost obsolete, but still works, and it can be plugged-in to a variety of power sources! The HANMATEK 110mhz DOS1102 only weighs a few pounds and exceeds my old scope in everything else. After it arrived an hour ago I looked through the handbook trying to acquaint myself with the parts and controls, but the hardest part was figuring out HOW TO TURN IT ON. The technical support guy I contacted gave me an URL and I watched a short promotional video that showed WHERE the power-plug went, which, if you don't know, is almost invisible on the left side. Not what I thought at all with 2 USB plugs (which are only for signals to a computer.) What's missing in the information on the Amazon page and the handbook is the most simple thing you just might want to know, like "How to turn it on!" Amazon needs to have that video, not the other one that shows you almost nothing... Once I found the small plug-in and pushed the on/off button, it popped on instantly with a beautiful color screen showing glorious fine detail. Oh, that's NICE! The Oscilloscope techniques will come around without much effort. I actually went to school at Lowry AFB in Denver to learn how to repair and calibrate these things and other delicate instruments. (At least instruments like a Hameg 20 MHz.) Now I'm not so sure because everything is on IC's and if something goes wrong it might just be cheaper to buy a new one (instead of trying to de-solder a chip from the board and replace it with the same model number chip, IF you can even find it...) The good thing about IC's is they use tiny voltages and currents and have greatly extended life compared to components like tubes, resistors, and capacitors. For now, I have a new, very compact and lightweight scope!

Per the advertised specs this thing is amazing for the price. I'm just a car mechanic so I maybe can't judge it as thoroughly as an electrical engineer, but for my use case it's awesome. The few other auto techs I've worked with that consistently use an oscilloscope for diagnostics use very expensive tablet style scan tools and very expensive obd2 dongles and instead of this little stand alone bad boy that costs less than the dongle you need to do O-scope stuff with an autel or snap on scan tool. As far as function, the wall wart to laptop-style barrel connector power supply is less than ideal, but it has never failed for me. I love the knob controls for the time window and voltage range settings vs tablet based touchscreen inputs. I pretty much only use it to monitor 5V /12V hall effect speed sensor waveform inputs for engine, transmission, and abs sensor signals and maybe a coil or injector control circuit for the one time in a hundred it's not obviously just a bad coil, injector, or circuit. Not really a must have tool for some car mechanics but for an decent diagnostic tech it's almost a necessity these days and this is a very good way to get a stand alone O-scope in your tool box in a package that also happens to be a very cheap, good looking, and effective.

Does the job, is easy to use, the size is perfect; and if needed can be used with a external battery, the display is ok, for the money 100mHz 500Sa is great if it last !

In my two decades as a ham radio operator and electronics tinkerer, I have NEVER used or owned an oscilloscope. I know, blasphemy. I had a little extra money burning a hole in my pocket and pulled the trigger on this model, and am pretty happy with it. It's rather compact and includes TWO probes! The probes alone are worth at-least $25 or $30. Anyway.. It took me a little time to actually learn how to use an oscilloscope in general, and once I did, I found this model easy to use and implement in my electronics bench. I'm very happy with my purchase, and do not regret it in the least. While this is NOT a Tektronics or higher end scope, for what I use it for, it serves it's purpose very well.

Great as an entry level scope. Even with one channel, the bandwidth is more that enough for most home projects.

I never used a scope before. This was very easy to use to trace a hard to find bug in a vintage tube amp build I did. For the price it's great if you are doing simplistic debugging like I do. There are features that people really like on the more expensive models, but I wouldn't know how to use them. Believe it or not, my next project for this scope is to debug and restore a 1959 Tektronics 541a scope. It's a bit of fun irony.

A: The scope seems great for your average electronics hobbyist making simple projects. Good value for the money when you consider the "nice" oscopes cost close to $1000. If you want to see your waveform this works. B: The screen capture functionality basically is useless. You have to START the oscope from turned off with the flash drive plugged in or it won't be recognized. Also, even when you do so, sometimes it will just freeze in the middle of trying to save a screen capture. Finally, unfortunately you can't unplug your flash drive to transfer photos in the middle of a session. If you unplug it when its on and plug it back in it won't be recognized forcing you to restart it and loose your signal and configuration settings. Really unfortunate.

Ha funcionado muy bien hasta ahora.

I got this scope as a multimeter is just too limiting. I'm using the Hanmatek to debug IOT projects and it is very handy for verifying serial communications between devices, and debugging signal paths. Its been 30 plus years since I've used a scope and this one is easy to use and figure out. In hindsight, scope with an external trigger would be slightly more useful, but this one does fine for my needs. The only negative I have is the probe tuning adjustment is super sensitive. Its not really an issue as all scopes at this price level are shipped with the exact same probe.

It's an OK unit. Not the greatest but considering the price I paid it was worth it. Good for beginners and simple usage.

I use HANMATEK products every day in my work, Digital Oscilloscope, Digital Multimeter, DC Power Supply Variable & Soldering Station, to whom I place all my confidence and security. I recommend their products to anyone starting out in electronics without hesitation.

Scope works okay, software and drivers are on a CD and I don't have a CD drive. The software I downloaded from the website doesn't come with working drivers so I can't use it. There are drivers, but they don't seem to work with my scope. Screen becomes discoloured when you push a button as pressure is being applied to the edge of the screen. Overall it works okay, but it is far from a 110MHz scope. Good for hobbyists, not great for professionals or high accuracy.

Much more stable, watch videos on its use
