How to Characterize Phase-locked-loop Signal Behaviors
应用文章
Digital communication systems often have unique carrier synchronization and synthesizer requirements such as rapid carrier acquisition/lock, and stable operation in demanding environments. The performance of these requirements is affected by not only oscillator characteristics themselves but also the design of phase-locked loop circuits interacting with unwanted stimulus such as microphonics. This paper discusses how Keysight Technologies, Inc. Signal Source Analyzer helps you to identify unwanted phase-locked loop transition “phase-hits”, and achieve easy, comprehensive and accurate phase-locked loop characterization in both linear and nonlinear regions.
Characterizing PLL Linear and Nonlinear Behaviors
Starting with test parameters in characterizing phase locked loop linear and nonlinear behaviors; there are three different stages of test usage, component evaluation, oscillator/ phase-locked-loop circuit design, and veriication/test at operating conditions.
