The properties of discrete estimations of instantaneous cross-spectral density and cross-spectral components, which are found on the basis of coherent estimations of cross-correlation estimations, were investigated; recommendation for choice of reading number, discretization step, corellogram truncation point for guaranty of the empirical cross-spectral analysis assigned certainty were investigated. Modernisation of the Vektor vibrodiagnostics system was carried out.
