Abstract: A method for analyzing the resolution and/or the accuracy of a transmission unit of a radar sensor is described wherein a transmitter signal is received via a receiving unit. At least one echo signal based on said received signal is simulated. The frequency difference of said transmitter signal and said echo signal is determined. Said frequency difference is filtered and transformed in order to obtain a transform. At least one maximum of said frequency difference in said transform is detected. Spectral properties of said frequency difference in said transform are determined. At least one quality parameter of said spectral properties is outputted. Further, a radar sensor is described.

Abstract: The invention relates to a measurement system, including a signal analyzer or monitoring receiver, for measuring and analyzing modulated signals. The system includes a signal acquisition device having input port(s), wherein the signal acquisition device is configured to capture modulated signal(s) applied to the input ports, wherein each captured modulated signal can be represented as an I/Q signal; wherein the signal acquisition device generates at least two digital I/Q data streams based on the one or more modulated signals, wherein the at least two digital I/Q data streams are generated in parallel. The measurement system includes a selection device to select at least one target frequency bandwidth in each of the at least two digital I/Q data streams; and a signal processing device configured to analyze the at least two digital I/Q data streams in the selected target frequency bandwidths.

Abstract: A method of setting a measurement instrument comprises the steps of: Providing a reference measurement instrument that uses at least one instrument parameter; Performing a training phase for a particular signal type to be processed by said reference measurement instrument in order to retrieve an optimal setting for said at least one instrument parameter; and Creating a lookup table for said particular signal type, said lookup table comprising at least said optimal setting for said at least one instrument parameter. Further, a system for setting a measurement instrument is described.
