Šumový generátor 230V,RF, filtre
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
Surround noise - noise in broadband electromagnetic radiation TEMPEST LGS503/449 protective systems 0.01 MHz - 2000 MHz
Noise generator. The operation of various devices (such as computers, recording technologies) may include signal generation (TEMPEST) containing classified or confidential information.
These signals can be intercepted using special equipment (USRP, spectral evaluators).
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).
