METHOD OF MEASURING METROLOGICAL CHARACTERISTICS OF MULTICHANNEL EQUIPMENT FOR MEASURING MUTUAL SPECTRA OF VIRO-ACOUSTIC LOADS IN FLYING VEHICLES Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: voltage is measured at outputs of two channels, as well as levels of random loads which are excited simultaneously by the same signal. Signals measured at output are compared, and phase-frequency characteristics of through circuits are frequency synchronized of through channels mated in pairs. Amplitude-frequency mutual power, phase-frequency and dynamic error are determined at frequency range of equipment to be calibrated. EFFECT: improved precision of measurement due to error reduction. 4 dwg
