Abstract


With the frequency source technology more widely, this paper briefly frequency source in the target, focuses on the phase noise of this very important indicator. Phase noise measurement in the measurement , control, instrumentation and other aspects of the importance of making many researchers conducted in-depth exploration. But the traditional phase noise measurement system circuit complexity , and the need to refer to the same frequency as the signal , which allows for different frequency source phase noise measurement is not easy to implement , but the cost is high. This paper studied the frequency based on the equivalent phase of the new phase noise measurement system that uses two different frequency signals directly equivalent phase methods, after signal processing to extract the phase noise information . Based on the principle of equivalence of the phase locked loop is key to the design of the system , third chapter of the module design are discussed in detail , locking experiments further illustrate the PLL phase noise can be a powerful new measurement principle guarantees implementation. Introduces a new application of the principle of the greatest common factor of two signal frequency, Chapter V gives effective solutions . This phase-locked loop to achieve a different frequency phase lock between the signals , the phase noise measurement system that exceeded the new reference source and the sample source to the same frequency limits , thus eliminating the need for expensive, high target frequency synthesizer, simplifies system design, significant cost savings .
