Claim Text:
1. Measuring system for nuclear magnetic measuring devices, comprising: a controller, a signal generator for generating and outputting electric excitation signals and a signal processor with an input stage and a signal conditioner following the input stage in a signal path of the signal processor for processing the electrical measuring signals effected by the excitation signals and being received at an input of the input stage, wherein interfering signals also effected by the excitation signals and not occurring simultaneously with the measuring signals are received at the input of the input stage, a signal swing of the measuring signal being less than a signal swing of the interfering signal, wherein the controller determines instants of time of outputting of the excitation signals, wherein a switch is arranged in the signal path of the signal processor between an output of the input stage and the input of the signal conditioner, the switch being switchable to a first switching state I and a second switching state II by the controller, wherein the signal at the output of the input stage is led to the input of the signal conditioner in the first switching state I, and wherein the signal at the output of the input stage is not led to the input of the signal conditioner in the second switching state II, wherein the controller is adapted to switch the switch in the first switching state I only in periods of time in which there are no interfering signals at the input of the input stage, and wherein a dynamic range of the input of the signal conditioner is adapted to the voltage swing of the measuring signals.
