1. A method of determining a noise-robust acquisition configuration for operation of a sensor system, comprising performing a noise scan, the noise scan comprising:
obtaining a sensor receive signal from the sensor system without a stimulus signal being applied to the sensor system;
determining a digital sensor receive signal from the sensor receive signal by A/D conversion of the sensor receive signal at a predefined noise scan frequency;
determining a plurality of decimated digital sensor receive signals by integer decimation of the digital sensor receive signal using two or more decimation rates that differ from each other, wherein respective ones of the two or more decimation rates are associated with a respective candidate acquisition configuration for the sensor system;
in response to determining the plurality of decimated digital sensor receive signals, determining one or more noise measures for multiple candidate acquisition configurations by evaluating one or more of the plurality of decimated digital sensor receive signals; and
using the one or more noise measures, determining the acquisition configuration for operation of the sensor system from the multiple candidate acquisition configurations; wherein
determining the acquisition configuration comprises selecting a preferred noise measure from the one or more noise measures and selecting a first candidate acquisition configuration of the candidate acquisition configurations, which first candidate acquisition configuration is associated with the preferred noise measure as the acquisition configuration.
