In a magnetic resonance system and an operating method therefor, a number of independently operable radio frequency signal generator modules are provided or respectively connected to radio frequency coils. A control unit provides a synchronization signal to each of the radio frequency signal generator modules to selectively operate the modules to achieve different types of signal transmission. One of the radio frequency signal generator modules can serve as a master module, that receives the synchronization signal directly from the control unit, and supplies the synchronization signal to the other modules, functioning as slave modules.
