Patents by Inventor Alfred ROSENKRÄNZER

Alfred ROSENKRÄNZER has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Test equipment, method for operating a test equipment and computer program
    Patent number: 10768221
    Abstract: A test equipment has a signal input/signal output and a use-site calibration unit for determining a user-site compensation function. The user-site compensation function has a compensation magnitude function and a compensation Hilbert phase function. The calibration unit has a level meter and a calculator. The level meter is configured to measure a magnitude characteristic of the electrical signal, the magnitude characteristic being the basis for the determination of the compensation Hilbert phase function. The calculator is configured to determine a Hilbert phase characteristic of the electrical signal based on a Hilbert transformation of a function dependent on the measured magnitude characteristic and to determine the compensation Hilbert phase function on the basis of the Hilbert phase characteristic.
    Type: Grant

  • Parameterized signal conditioning
    Patent number: 7434118
    Abstract: A coupling unit is adapted to be coupled between a first and a second unit to be tested. Said coupling unit comprises a first signal path that is adapted to provide a signal connection between at least one terminal of the first unit to be tested and at least one terminal of the second unit to be tested. The first signal path comprises a signal conditioning facility adapted for receiving a first signal from the first unit to be tested, for conditioning said first signal in accordance with predefined parameters, and for providing the conditioned first signal to the second unit to be tested.
