My item never worked. Been a while since I purchased but yea never even turned on and I'm too lazy to ask for another.

I purchased this for a small one time only learning activity I was doing for others. This was easy to setup because of the lack of options. This is as simple as it gets. I have used much better ones in labs, but for the cost this performed its intended function well.

Super Gerät aber die Bedienunganleitung ist sehr verbesserungswürdig !

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!

Das Oszilloskop bietet ein hervorragendes Preis/Leistungsverhältnis und vielfältige Auswertemöglichkeiten. Wesentliche Kriterien sind für mich 4 Kanäle, FFT-Analyse und 100 MHz (1G-Sample) und Flexibilität mit Powerpack Akku.Bei dem Preis ist dabei natürlich nur eine Auflösung von 8 Bit möglich. Das entspricht einer Auflösung von besser als 1%, was in der Regel völlig ausreicht. Die möglichen 256 Bit auf einen 480bit Bildschirm hochskaliert mit den typischen Toleranzen von +/- 1 Bit führen zu einem „Rauschen“ in der Darstellung von 2-3 Bit, wie oft kritisiert. Das ist logisch und stört mich nicht. In den vielen Untermenus gibt es eine Mittelwertbildung. Dann ist das Ergebnis völlig glatt. Dass das Netzteil stört, konnte ich nicht verifizieren. Der Betrieb mit einem Powerpack ist problemlos.Ich habe seit Jahren hochwertige analoge Oszillographen. Ich wundere mich, was mit diesem Gerät alles möglich ist und dass es so gut funktioniert. Ich würde es sofort wieder kaufen.

Long time user of high end Tek, Philips etc. I find this scope very capable and more than I need for my hobby. I still have my Tektronics scope. If my office gets cold I will turn it on.

Use low-end Tektronix at work, bought this for home. Have to say that the Hanmatek DOS1102 has several aspects, mainly on ease of use, that are superior to Tektronix in the same speed class.1. AC/DC coupling is a top-level menu item. (Tek requires six button clicks and a knob turn to make this simple change. What was Tek thinking?)2. "Analog" adjustments like position knobs and trigger level have a better default resolution and speed, and thus do not require the tiresome coarse/fine menu that the Tek does.3. Very convenient "show all measurements" quick screen for when you don't want to waste time setting up several different individual measure parameters.4. Reasonably quick boot without any pushback or questions when powering on.5. Seems better than Tek about not putting junk in front of the waveform you're trying to see, but maybe that's because item 3 above means you'll have less need to post measurements on the screen.Now the downsides:1. Most sensitive scale is 20mV/div with X1 probe, about 2mV rms noise on this scale.2. As some other commenters mentioned, there's about 1-2 pixels noise on the trace regardless of scale that gives it a crawly kind of look.3. Single shot capture works great but is less convenient than other scopes; the first shot is easy but to do another you have to scroll back through all the trigger mode options to get back to Single. The Run/Stop resets the scope to Auto mode.Oddities, not necessarily downside:1. XY mode splits the screen into a small XY display, a small YT display, and a text box. I'd have preferred full screen XY but seeing both at once also has some advantages.Subjective stuff:On the good side, handles more like a traditional scope compared to some others, controls respond quickly, and stuff that would be front panel on an analog scope tends to be on the top menu instead of hidden. On the downside, the knobs are soft both in texture and in the detents. I'd have liked harder plastic and a more robust detent.Overall:Impressive value for a $170 scope if you're not doing small signal work.

Altijd al een 4 kanaals scoop willen hebben. Had wel een 2 kanaals scoop alleen op de PC. Maar dat is toch anders dan een losstaand model.Alle kanalen gecontroleerd. Alles werkt prima. Heeft meer functies dan ik gewend ben. Altijd goed.

I always want a scope for field use, something that I can pack in a suitcase and has an input bandwidth that I can see most of the signals on my boards. This scope is very small (and light!) yet it has an input bandwidth of 110 MHz, a large screen, with all the basic functions that a digital scope should have, and it's so economical I almost thought that I bought a DMM. It's good for field use, and it's so easy to move from test to test in a lab setting. The bandwidth covers most of my needs. I even use it on signals that have a rise time below 20 ns. Yes, I know I fold in the rise time a little bit that from the scope, but just checking if I have a signal a not, that's good enough. If I really need to have a precision measurement, I roll out my heavy scope with 500 MHz to 1 GHz bandwidth (but I also paid a hell lot more for those scopes and I do not really want to use them unless I have to). Another great use of this scope is in undergraduate research or senior design projects. Breaking things is a natural process of learning and believe me, students are very good at that (the breaking part, not always the learning part that should follow). I work with several students a year on such projects, I now have a scope for them, and I will ask them to try out all the functions, including the remote connection and DAQ part, that I find very useful but have no time to use myself.
