Abstract
A magnetic resonance tomography system has a frequency control device for temperature compensation, a temperature sensor, and a high frequency generator. An output frequency of an output signal from the high frequency generator is dependent on a value of a digital frequency variable, and a synthesis signal with the system frequency is generated dependent on the output signal. A temperature change is detected using the temperature sensor, a temperature-time function of the temperature is determined using the temperature change that has been detected, a time is determined at which a change in the digital frequency variables in the least significant bit brings about a change in the frequency of the synthesis signal that corresponds with a change in the system frequency due to a temperature, according to the interpolated temperature-time function, and the digital frequency variable in the least significant bit is changed at the specified time.
