1. A magnetic resonance tomograph comprising:
a transmitting antenna;
a receiving antenna; and
a high-frequency unit configured to switch over the transmitting antenna, the receiving antenna, or the transmitting antenna and receiving antenna from a transmitting state to a receiving state in a period of less than 40 microseconds, wherein the high-frequency unit comprises a drive circuit that is in signal connection with at least two detuning devices or at least one detuning device and a duplexer, wherein the drive circuit further comprises a synchronization device configured to limit jitter on simultaneous switchover to a value of less than 5 microseconds, 2 microseconds, or 1 microsecond.
