Abstract :
The tuning speed of frequency synthesizers is usually specified by either phase or frequency settling. The paper shows that in frequency hopping systems phase settling characteristics correspond to system performance better than frequency settling characteristics. Simulation results are compared to a mathematical analysis, and intuitive explanations are used to clarify this paradoxical relationship. Specific phase settling specifications are discussed
