Characterizing phase-locked loops with waveform scans
Identifying frequency stability problems within a phase-locked loop design can be greatly simplified when using an automated method. When an oscilloscope detects the period of a waveform cycle, this value can be directly inverted to compute the instantaneous frequency of the specific waveform cycle. ...
