ANALYSIS OF HARDWARE ERRORS OF PHASE FLUCTUATION STRUCTURAL FUNCTION ANALYZERS
(pp.44-54)

Abstract. The paper considers the accuracy of phase-measuring equipment due to hardware, methodological and instrumental errors in measuring the structural function of phase fluctuations and, in particular, the influence of the constant component of the phase shift when measuring the statistical characteristics of phase fluctuations using key phase detectors on triggers and coincidence circuits. The corresponding mathematical apparatus is proposed, adequate to the physical and technical nature of phase fluctuations, analytical expressions are given for the hardware components of errors in measuring the parameters of phase fluctuations: mathematical expectation, dispersion and structural function, allowing one to evaluate random processes in a radio engineering system.

Keywords: measurement, phase methods, frequency, error, noise immunity.
