1. A pilot tone signal generator comprising:
a receive unit comprising a first sensor and a second sensor adjacent to the first sensor;
an inverter; and
a summation element,
wherein the first sensor of the receive unit is configured to receive a synchronization signal of a system control unit of a magnetic resonance tomograph,
wherein the synchronization signal comprises a clock signal,
wherein the synchronization signal is an optical data signal,
wherein the first sensor of the receive unit is configured to create a first output signal from the optical data signal,
wherein the second sensor is configured to create a second output signal from the same optical data signal,
wherein the first output signal has an inverse amplitude to the second output signal,
wherein the inverter is configured to invert the first output signal of the first sensor to provide an inverted output signal,
wherein the summation element is configured to add the inverted output signal of the first sensor and the second output signal of the second sensor to provide an electrical sensor signal, and
wherein the pilot tone signal generator is configured to emit a pilot tone signal as a function of the electrical sensor signal.
