    • In order to determine various operational parameters of a power amplifier (for example, a complex load impedance or a complex forward and return power or a reflection factor or a voltage standing wave ratio) on a connecting line between an output of the power amplifier and a complex load, complex analog forward and return voltages on the connecting line are determined by an analog coupling device. These analog voltages are digitized and converted down into a baseband by one or more digital down-converters. From these digital values corresponding in absolute value and phase to the complex forward and return voltages and present in the baseband, desired operational parameters may then be calculated by a computer.
    • 为了确定在功率放大器的输出与一个功率放大器之间的连接线上的功率放大器的各种操作参数(例如,复合负载阻抗或复合正向和返回功率或反射系数或电压驻波比) 连接线上的复杂负载,复合模拟正向和返回电压由模拟耦合装置决定。 这些模拟电压被数字化,并由一个或多个数字下变换器转换成基带。 从绝对值和相位对应的这些数字值到复合正向和返回电压并存在于基带中,然后计算机可以计算所需的操作参数。
