1. A magnetic resonance tomography scanner comprising:
a receiver;
a transmitter, wherein the transmitter is configured to generate and output a first two-tone signal with a first frequency, a second frequency, and a level; and
a coil configured to receive the first two-tone signal directly from the transmitter,
wherein the first frequency, the second frequency, and an odd-order or higher-order intermodulation product of the first frequency and the second frequency lie in a receiving range of the receiver,
wherein the first frequency is not equal to the second frequency, and
wherein the level of the output first two-tone signal lies in a level range in which the received two-tone signal at the receiver lies in a linear range of the receiver, and the odd-order intermodulation product lies above a noise level of the receiver.
