Claim:
1. A magnetic resonance system comprising: a local coil comprising a test signal transmission interface operable to: a test signal receiving interface operable to receive the defined test signals injected via the plurality of test signal coupling units into the plurality of magnetic resonance antenna elements in the calibration operation, or the defined test signals emitted by the plurality of magnetic resonance antenna elements and detected by the respective test signal coupling units; and an analysis unit configured to determine current relative phase responses of the receive chains of the individual magnetic resonance antenna elements of the plurality of magnetic resonance antenna elements on the basis of the defined test signals injected into the plurality of magnetic resonance antenna elements, determine current relative phase responses of the transmit chains of the individual magnetic resonance antenna elements of the plurality of magnetic resonance antenna elements on the basis of the respective test signals detected by the test signal coupling units.
