Analytical expressions are derived for determination of time of the frequency and phase stabilizing in the pulse-phase lock system of the frequency synthesizer with the mode of beats and switching of the pumping currents and elements of the low-pass filter. Results of computations using the derived relations are compared with results of simulation using MATLAB/Simulink. The study results are reduced to simple formulas and tables.
