The Fnirsi 1031D is a portable and robust oscilloscope at a great price. I know the usual negative reviews about the product. yes - there are points of criticism, but one should consider the unbelievably low price: The advertised 100 MHz bandwidth is not achieved in practice, but 70 - 80MHz MHz does the part without any problems, and that's more than OK for the price Both sensitivity and measured values are based on the selected vertical screen resolution. Thus, for example, input signals which are smaller than 1 raster unit are not shown. Or, for signals that extend beyond the display range, the voltage values are calculated incorrectly. The absolute sensitivity in the highest resolution is e.g. 50mV - signals with lower levels are output as a flat line. That is certainly a point of criticism. It's a bit of a shame that the manufacturer saved on the included power supply. The documentation prescribes a 2A power supply - a 1A power supply is delivered. The manufacturer should consider this. Conclusion: It is definitely not a high-end device for professional use, but a low-cost second- or -hobby device with amazing capabilities. I can recommend this device under the conditions mentioned above. Therefore, despite the criticisms raised, I give it 4 stars. One star falls victim to the weak power supply. Buyers with a professional claim definitely invest more in a true professional device. It doesn't make sense to buy a VW Golf, and then fault lack of four-wheel drive or lack of luxury. If you are looking for a solid, affordable, and mobile device, you will find it with the Fnirsi 1013D.

Das Fnirsi 1031D ist ein mobiles und robustes Oszilloskop zu einem Hammer-Preis. Ich kenne die üblichen negativen Rezensionen zu dem Produkt. ja - es gibt Kritikpunkte, aber man sollte hierbei den unfassbar günstigen Preis bedenken: - Die beworbene 100 MHz Bandbreite wird in der Praxis nicht erreicht, aber 70 - 80MHz MHz schafft das Teil ohne Probleme, und das ist mehr als OK für den Preis - Sowohl Empfindlichkeit als auch ausgegebene Messwerte orientieren sich an der gewählten vertikalen Screenauflösung. So werden z.B. Eingangssignale, die kleiner als1 Rastereinheit sind, nicht dargestellt. Oder für Signale, welche über den Anzeigebereich hinausragen, werden die Spannungswerte falsch berechnet. Die absolute Empfindlichkeit in der höchsten Auflösung ist z.B. 50mV - Signale mit weniger Pegel werden als flache Linie ausgegeben. Das ist durchaus ein Kritikpunkt. - Etwas schade ist, dass der Hersteller am mitgelieferten Netzteil gespart hat. Die Dokumentation schreibt ein 2A Netzteil vor - geliefert wird ein 1A Netzteil. Das sollte der Hersteller überdenken. Fazit: Es handelt sich definitiv nicht um ein Highend Gerät für den Profieinsatz, sondern um ein preisgünstiges Zweit- oder -Hobbygerät mit erstaunlichen Fähigkeiten. Unter den genannten Rahmenbedingungen kann ich das Gerät empfehlen. Deshalb gebe ich trotz der angesprochenen Kritikpunkten 4 Sterne. Ein Stern fällt dem schwachen Netzteil zum Opfer. Käufer mit Profi-Anspruch definitiv mehr in ein echtes Profigerät investieren. Es ist nicht sinnvoll, einen VW Golf zu kaufen, und dann fehlenden Vierradantrieb oder mangelnden Luxus bemängeln. Wer ein solides, preisgünstiges, und mobiles Gerät sucht, wird mit dem Fnirsi 1013D fündig.
