Abstract

A device has a first control loop (28) with which a frequency RF of an RF generator is synchronized with a resonance frequency F0 of an NMR line. A phase shifter (22) is provided to rotate the radio frequency phase of the NMR receiver system in the first control loop. The phase shifter is controlled by a second control loop (27) whose input signal comes from a signal extraction stage.
