Performance characteristics of radiomonitoring receivers are depends on chosen microwave frequency measurement method. Recently instantaneous frequency measurement method of radio and microwave signals based on the fast Fourier transform was proposed. At moment it is lacking of quantitative frequency measurement error analysis or frequency error sources analysis for proposed method. The article goal is exploration of frequency error sources and its quantitative analysis. Analytic and numeric model of digital frequency measurement sub-sampling receiver are intended and researched Relative frequency error charts at two signal-to-noise ratio at two analog-to-digital converter aperture jitter values are derived.

Numerical frequency error analysis of digital frequency measurement receiver sub-sampling sinusoidal signal is provided. Digital receiver exploits frequency measurement method based on the Fast Fourier transform with input signal sub-sampling. Analytic and numerical model of digital receiver are intended and numerically investigated. Frequency error sources are established and discussed. Frequency error graphs dependent on signal-noise-ratio and ADC aperture jitter are derived.
