    • 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 e00, e01, e10 and e11, are determined as a function of a frequency f and the signal values v1(t) and v2(t) are transformed into the frequency domain as wave quantities V1(f) and V2(f), and absolute wave quantities a1 and b1 in the frequency domain in the calibration plane are calculated from the wave quantities V1(f) and V2(f) by the error terms e00, e01, e10 and e11.
    • 一种用于确定在校准平面中的时域中的RF信号的电压u(t)和/或电流i(t)的方法,其中通过具有两个输出和一个信号的至少一个定向耦合器输入第一分量 从校准平面方向的信号输入的第一RF信号和从校准面沿信号输入方向延伸的第二RF信号的第二分量被解耦。 对于定向耦合器的双端口误差,误差项e00,e01,e10和e11被确定为频率f的函数,信号值v1(t)和v2(t)被转换为频域 作为波量V1(f)和V2(f),并且通过误差项e00,e01从波量V1(f)和V2(f)计算校准面中频域的绝对波量a1和b1 ,e10和e11。
