英文摘要：

The Voltage Control Oscillator is used as a source of radio-frequency signal. By the means of adjusting the modulating frequency, the relative phase can be changed. In addition, the phase noise of the Voltage Control Oscillator is discussed. This is an attempt to miniaturization and integration of experimental instruments.
