Abstract: A predistortion system for optimizing the performance of a distorting component. The predistortion system comprises a signal generator, the distorting component, an analyzing device for frequency and/or time domain analysis, and a predistortion device. The signal generator generates a first signal according to a reference signal. Furthermore, the first signal after being passed through the distorting component results in a second signal. Then, the second signal after being passed through the analyzing device results in a third signal. Moreover, the third signal after being passed through the predistortion device results in a compensated signal. In addition to this, the reference signal is provided for the predistortion device.

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 method for investigating signal parameters in an electrical measuring device with a display element with the method steps: display of a detected signal on the display element, manual masking of at least one signal component of the signal by a user by means of a masking element of the measuring device and investigation of signal parameters from the masked signal component or from the unmasked signal component of the signal by the measuring device. At least one further signal parameter is also investigated alongside the time duration and the bandwidth of the masked signal component. According to the invention, a corresponding measuring device is also provided.

Abstract: A measurement device and a method for data visualization and three-dimensional display are provided. The measurement device comprises a measuring unit, a memory, storing measurement results measured by the measuring unit and which are a function of at least two different measurement parameters, a processor and a display. The processor is configured to create a three-dimensional, 3D, graph of the measurement results stored in the memory, and to automatically compute, on the basis of at least one point of interest in the form of a data marker, two cross-sections of the 3D graph along different planes, whereby one of the sides of each cross-section terminates at the surface of the 3D graph and includes the position of the at least one data marker. The display displays the 3D graph of the measurement results, the at least one data marker and at least one of the cross-sections of the 3D graph associated with the at least one data marker.

Abstract: A measuring device for phase-coherent analysis of frequency-hopping signals is provided. The measuring device comprises a signal acquisition unit and an analyzing unit. Whereas the signal acquisition unit is configured to obtain an In-phase/Quadrature-phase-signal (I/Q-signal) and to provide said I/Q-signal for the analyzing unit, the analyzing unit is configured to detect hop occurrences at nominal hop frequencies based on the provided I/Q-signal. In addition to this, the analyzing unit is further configured to specify at least one common reference frequency with respect to the hop occurrences.
