Noise generator 230V, RF, filters
The filter is designed to protect against information leakage via 230 V power lines. It is used for electromagnetic power separation of electronic devices from the electrical grid.
-Protection of office equipment against hf external interference;
AC circuits pose a double threat. First of all, acoustic data can be leaked through the AC circuit (230 V). And secondly, there is a threat of information signals leaking from office equipment.
There exist passive and active techniques for AC (220 V) protection against unauthorized data retrieval
Broadband electromagnetic radiation generator TEMPEST LGS505/451
Noise generator. TEMPEST signals containing confidential information may appear when different devices (such as computers) are in operation. These signals can be intercepted using special equipment (USRP, spectral evaluators).
Noise generator. TEMPEST signals containing confidential information may appear when various devices (e.g. computers, recording technologies) are operated. These signals can be intercepted using special equipment (USRP, spectral evaluators).
Based on these intelligence leaks was developed by Russian companies Generator of radio broadband electromagnetic radiation which are designed to operate in a protected room and active protection of information systems (BACS ). Providing protection against leaks through TEMPEST channels by stopping the boundary of the broadband electromagnetic noise control area that can be spurned or secured to the wiretap.
