The noise generators GNOM-3M, GNOM-3M-60V are designed to operate as part of an active protection system for information processed at second- and third-category electronic computing facilities from leakage via channels of side electromagnetic radiation and interference (SEMI), via the primary power supply network and ground loop by creating noise electromagnetic interference in the frequency range from 0.15 to 1800 MHz. The generators have four non-correlated channels (outputs) designed for connection to antenna circuits and primary power supply circuits. The generators operate in conjunction with external antennas. GNOM-3M is powered by an AC network of 220 V, 50 Hz. GNOM-3M-60V is powered by a DC source of 60 V ± 20%.
