Abstract
A method for determining and/or adjusting phases of at least two electrical signals is disclosed. The method includes the following steps: a first frequency and/or a first power level for a first signal is set and a second frequency and/or a second power level for a second signal is set. The first signal and the second signal are superposed, thereby obtaining a superposed signal. A power parameter of the superposed signal is determined via a power measurement unit for several different phase offsets of the first signal and/or of the second signal. A relative phase between the first signal and the second signal is determined and/or set based on the determined power parameters. Moreover, a signal generator system is disclosed.
