Systems are designed to measure the AC voltage corresponding to the values of vibration parameters (vibration acceleration, vibration velocity, and vibration displacement), reproduction of AC frequency measurements and measurements of nonlinear distortion coefficient. Structurally, in the basic configuration, the system is designed as an instrument unit connected to the computer network port via Ethernet interface and a set of connecting cables. The principle of operation is based on amplification of output electrical signals of primary measuring transducers (PMT) installed on the tested items, conversion of measuring signals into digital code, further processing of measuring information in the computer and outputting it to external devices in the form convenient for the user, as well as the formation and regulation of control signals of the vibration test bench so that the measured vibration parameters correspond to the specified test profile.
