Abstract: A control device includes an acquiring unit and a processing unit. The acquiring unit acquires a voltage course and a current course of a determinable number of periods of a frequency generator and transmits these to the processing unit. The processing unit determines a temporal offset ?t1 between a rising edge of the current course and a rising edge of the voltage course for each period of the determinable number of periods, and further determines if this temporal offset ?t1 is positive or negative. The processing unit determines a difference between the number of periods with positive temporal offset and the number of periods with negative temporal offset within the determinable number of periods, and generates and adapts a switching signal for a switch-on time of the voltage course if the number of periods with positive temporal offset differs from the number of periods with negative temporal offset.

Abstract: An energy supply unit for a traveling wave tube is configured to transform a first voltage present at a low voltage interface into a second voltage providable at a high voltage interface. The second voltage is greater than the first voltage and corresponds to a required operating voltage of the traveling wave tube. The energy supply unit is configured to receive a signal pattern via a signal input interface and to output a control signal via a control interface to the traveling wave tube for operating the traveling wave tube based on the signal pattern and to gradually and/or iteratively align or adapt the control signal to the signal pattern being present at the signal input interface when changing an operating mode of the traveling wave tube. A power draw at the beginning of the switched-on state may increase slowly and voltage drops at the high voltage supply may be minimized.
