2 in1 Digital Storage Oscilloscope with Built-in Waveform Generator, 110MHz Bandwidth, 2 × 500MSa/s Sampling Rate, Dual-Channel DOS1102S

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.

This is an amazing scope for the money. I have had it for a few days and I am very impressed. I like it better than my Tektronix TDS 2014, it has more features and a far better display. My favorite features: excellent trigger menu, up to eight instant measurements per channel, beautiful display and ease of operation. I will probably buy a few more of these!

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 !

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.

Great o scope works fine all the controls work well and good scren great value for the money

This scope is ok, Its the test leads that come with it that I really have a problem with. The alligator clips on the leads are really hard to open and are easily bent out of shape when you are trying to open them. They are far too small to grip easily and slip around in their silicone insulating cover. I would return the whole scope if I were not outside of the return window.

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.

Only scratched the surface of its capabilities but not disappointed so far. Being of an older generation of electronics technician (I can remember vacuum tubes and discrete transistors was the basis). This digital scope easily replaces three or more pieces of older style test gear. Especially if you have limited bench space. Thumbs up.

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。

Ich war zugegeben etwas skeptisch – der Preis ist deutlich unter dem, was man sonst für ein 4-Kanal-Digitaloszilloskop erwartet, und auf YouTube gibt es eine Mischung aus Lob und Stirnrunzeln. Aber nach ein paar Tagen im Einsatz kann ich sagen: Das Gerät macht genau das, was es soll – und das absolut solide. Ich habe die 4-Kanal-Version DOS1104-4 und setze sie in einem Projekt ein, bei dem zwei Sensoren kalibriert werden mussten. Das Oszilloskop hat mich hier wirklich überrascht: Die Anzeige ist scharf und ausreichend groß, auch wenn sie bei starkem Umgebungslicht etwas spiegelt. Die Bedienung ist zunächst etwas gewöhnungsbedürftig, besonders wenn man von klassischen analogen Geräten kommt – aber genau da liegt für mich auch der Vorteil: Wer mit Knöpfen, Drehreglern und einem klar strukturierten Menü arbeiten kann, wird sich schnell zurechtfinden. Kein Touch-Gimmick, keine Animationen – dafür klare Menüs und direkte Funktion. Die Messfunktionen sind umfassend, die Auto-Set-Erkennung reagiert schnell, Trigger funktionieren sauber, auch bei niedrigem Pegel. Besonders hilfreich war die Möglichkeit, die vertikale Kalibrierung pro Kanal manuell anzupassen – das hat bei mir dafür gesorgt, dass beide Sensorsignale nach der Kalibrierung stabil dargestellt wurden, und Rechtecksignale nicht aussehen wie Treppenhäuser. Rechteck bleibt Rechteck – und das ist nicht bei jedem Billiggerät so. Die Speicherfunktion (Speichern von Screenshots und Daten via USB) funktioniert ohne Probleme – Stick rein, Datei drauf, fertig. Die Tasten fühlen sich okay an – kein High-End, aber auch kein Billigspielzeug. Das Gehäuse ist robust, der Griff und die verstellbaren Füße eine tolle Idee. Fazit: Kein Tektronix, aber für den Preis einfach überzeugend. Wer ein solides, zuverlässiges 4-Kanal-Gerät für Labor, Werkstatt oder Hobby sucht, macht hier nichts falsch. Bei mir bleibt’s auf dem Tisch.

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

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.

Very good quality. Recommend to buy.
