FIELD: radio engineering.
SUBSTANCE: method is based on generation of spectra of reference and tuned generators of the phase-locked loop frequency control system, analysis of spectral components. The device to determine working parameters of phase-locked loop generator frequency control comprises a reference generator of high frequency-stable oscillation, a phase detector, a DC amplifier, a low pass filter, a tuned generator, two spectrum analysers, a unit to determine phase detector characteristics and a recorder.
EFFECT: expanded range of determined working characteristics, higher resilience and stability of device operation.
