Frequency and Phase Settling Time Measurements on PLL Circuits

Frequency hopping is one of the most common methods to avoid interference and to increase security. As data throughput is a key parameter for wireless transmission systems, the time for a frequency change or hop is essential. Frequency settling time is therefore a very important measurement for the synthesizer developers.

This application note provides basic information about frequency and phase settling time measurements and how the measurement is implemented inside modern phase noise analyzers.

Measurement examples show the possibilities of this measurement feature and help the user to understand and use this method.
