A high-frequency signal stimulator system has at least two mutually independent data producers, signal processing and a signal generator. The at least two mutually independent data producers are each configured to produce at least one data packet describing a high-frequency signal to be produced. The signal processing is configured to extract a signal of the data packet produced by the first of the at least two mutually independent data producers and contents of the data packet produced by the second of the at least two mutually independent data producers. The signal generator is configured to produce a high-frequency signal based on the extracted contents.
