In a method for controlling a magnetic resonance system with a number of individually controllable transmission channels, a limited number of antenna control parameter sets are available that are associated with respective different examination situation classes that are defined with regard to specific examination situation parameters. The antenna control parameter sets include, for each of the transmission channels, a channel value or a channel value combination with which a relative amplitude and a relative phase of a radio-frequency signal emitted via the appertaining transmission channel are defined. Respective current examination situation parameter values to be associated with the examination situation parameters for the magnetic resonance measurement to be implemented are then detected and one of the examination situation classes is selected based on this. The magnetic resonance measurement is then implemented with the antenna control parameter set associated with the selected examination situation class.
