【Abstract】 The phase noise is not only the main specification for the signal generators of the radar, communication and ECCM, but also the main basis to measure the spectrum purity of the frequency synthesizer. The function and operating principle for the general measurement system of the phase noise are discussed in this paper, with an emphasis on the hardware composition as well as the design and realization of the software for the system .更多还原
