Auf diese Weise wird auch erreicht, daß unabhängig von der Zahl der in einem bestimmten Gerätetyp jeweils benutzten Umsetzerstufen mit einer einheitlichen Form der Oberwellenspeisung gearbeitet werden kann.In this way it is also achieved that regardless of the number of devices in a particular type of device The converter stages used in each case worked with a uniform form of harmonic feed can be.
Die Erfindung ist nicht auf das angeführte Beispiel der Addition von Frequenzen mit Modulatorschaltungen beschränkt. Vielmehr kann jede Art von Anordnungen zur Frequenzaddition also auch mittels synchronisierter Oszillatoren, die wegen der Kopplung durch Frequenzteiler mit identisch ausgeführten Einzelstufen bestückt sein können, vorteilhaft nach dem erfindungsgemäßen Verfahren ausgeführt werden.The invention is not limited to the example given of the addition of frequencies with modulator circuits limited. Rather, any type of arrangement for frequency addition can also be done by means of synchronized oscillators which, because of the coupling through frequency dividers, are designed to be identical Individual stages can be equipped, advantageously carried out according to the method according to the invention will.
Ebenso kann jede bekannte Möglichkeit zur Aussiebung der Oberwellen benutzt werden, soweit die geforderten Selektionsbedingungen die eine oder andere Art der Aussiebung zweckmäßig erscheinen lassen.Any known possibility for filtering out the harmonics can also be used, provided that the One or the other type of screening appear expedient under the required selection conditions permit.
Anordnung zur Durchführung des Verfahrens nach Hauptpatentanmeldung Sch 18136 Villa/ 21a4 (Auslegeschrift 1000 060), dadurch gekennzeichnet, daß die in den nach der Hauptpatentanmeldung identisch ausgeführten Einzelstufen \rerwendeten Normalfrequenzoberwellen gleichzeitig erzeugt werden und jeder Einzelstufe die jeweils benötigte Frequenz über einen Wahlschalter zugeführt wird, mit dem jede der benötigten Oberwellen gewählt werden kann.Arrangement for carrying out the method according to main patent application Sch 18136 Villa / 21a 4 (Auslegeschrift 1 000 060), characterized in that the r erwendeten normal frequency harmonics are generated simultaneously in the same exported to the main Patent Application single stage \ and each individual level supplied to the frequency required in each case via a selector switch with which each of the required harmonics can be selected.
