Ich habe heute morgen ein Oszilloskop im Smartphone Format gefunden, das DSO Nano.
Vom Aussehen her sieht das Oszi wirklich nett aus:
Vor allem das Display ist nett, aber die inneren Daten zählen halt. Besonders bei Messgeräten. Schließlich will man ja keinen Quatsch messen.
Die technischen Daten überzeugen dann doch weniger:
