    • While a spectrum waveform of an output signal from a subtracter (207) is visibly monitored, an operator controls a variable phases shifter (208) based upon a second control signal (CL2) so that a shape of a spectrum waveform of an output signal from a subtracter (207) is approximated to a spectrum waveform of a desirable wave to change a phase of a local oscillation frequency signal from a local oscillator (206). As a result, a phase of a duplicated loop signal is changed. Also, the operator controls a variable attenuator (209) based upon a first control signal (CL1) so that a shape of this spectrum waveform is approximated to a spectrum waveform of a desirable wave (20) to change a signal level of the duplicated loop signal.
    • 当可见地监视来自减法器(207)的输出信号的频谱波形时,操作员基于第二控制信号(CL 2)控制可变相移器(208),使得输出信号的频谱波形的形状 近似于从本地振荡器(206)改变本地振荡频率信号的相位的期望波的频谱波形。 结果,改变了重复的环路信号的相位。 另外,操作员根据第一控制信号(CL 1)控制可变衰减器(209),使得该频谱波形的形状近似于期望波(20)的频谱波形,以改变复制的信号的信号电平 回路信号。
