Abstract
A method for determining electric voltage u(t) and/or electric current i(t) of an RF signal in the time domain in a calibration plane, wherein by at least one directional coupler having two outputs and one signal input a first component of a first RF signal that runs from the signal input in the direction of the calibration plane, and a second component of a second RF signal that runs from the calibration plane in the direction of the signal input is decoupled. For a two-port error of the directional coupler, the error terms e, e, eand e, are determined as a function of a frequency f and the signal values v(t) and v(t) are transformed into the frequency domain as wave quantities V(f) and V(f), and absolute wave quantities aand bin the frequency domain in the calibration plane are calculated from the wave quantities V(f) and V(f) by the error terms e, e, eand e.
