next generation technologies in radar and satellite communication with high data rates call for innovative testing solutions to develop and manufacture rf components like voltage controlled oscillators (vco). the r&s®fspn phase noise analyzer increases efficiency and reproducibility of vco characterization and phase noise measurements from lab to production.voltage controlled oscillators are oscillators whose output frequency is controlled by means of an external tuning voltage, and they are used in a wide variety of electronic and rf applications like function generators, phase-locked loops including frequency synthesizers used in communication equipment. different vco design approaches yield different parameters and performance, and therefore it is important to measure or characterize vcos under different conditions. this application note provides a short technical introduction to voltage controlled oscillators and explains the most common and the most important measurements made during the vco characterization process.

提高高速数字设计和无线通信的数据率，需要具有低加性相位噪声和高抖动衰减的串行解串器锁相环 (serdes pll) 和时钟合成器。现代设计通常采用由抖动衰减器和频率合成器组成的两级架构。相位噪声分析仪具备一流的相位噪声灵敏度，是执行此类测试的首选仪器。为了激励 pll，需要具有超低相位噪声的附加信号源。
