    FNIRSI DSO-TC4

    Das Gerät funktioniert einwandfrei.
    Nur die Funktionsbeschreibung könnte etwas ausführlicher sein.
    Ich habe einige Zeit gebraucht, bis ich herausbekommen habe, wie man beim Generator die Kurvenform festlegen kann.
    Masn muß die angzeigte Kurve berühren - dann erscheint ein neues Fenster, indem man die gewünschte Form auswählen kann.
    Ansonsten gibt es nichts zu meckern.
    Besten Dank
