- s***l (855)- Feedback left by buyer.Past monthVerified purchaseDer Sinusgenerator ist an und für sich gut, sehr niedriger Klirrfaktor. Frequenz ist allerdings nur 956 Hz, nicht 1.000 Hz. Was schwach ist, ist die Dokumentation. Der Verkäufer konnte auch nicht weiterhelfen, bei der Frage nach der Formel zur Berechnung von R11, welcher bei Änderung der Frequenz mit angepasst werden muss. Ich musste sie selbst erörtern. Siehe angehängtes Bild.
