Latest Patents

Zietz's latest patents include a time domain measuring method with calibration in the frequency range. This method involves determining an electric voltage u(t) and/or an electric current i(t) of a high-frequency signal in an electrical cable on a calibration plane by measuring in the time domain. The process utilizes a directional coupler to decouple portions of the HF signal, which are then analyzed to convert them into the frequency domain. The calibration parameters are determined in a previous step, allowing for accurate measurements of absolute wave frequencies.

Another significant patent is a method for calibrating a test rig. This method involves a test apparatus with directional couplers for gauging a two-port test object. A vectorial network analyzer is connected to the test ports, enabling the determination of scatter parameters for various calibration standards. Corrections to the scatter matrix are made to obtain a corrected scatter matrix, which is essential for accurate measurements.
