Matrix of values of covariances for modulating processes of different spectral components of vibration signal as periodically non-stationary random process (PNRP) is proposed to characterize condition of mechanism. The values of covariance coefficients as a elements for matrix, represents the specific features of the modulating processes for each spectral pair.
