TEMPEST protective systems

Operation of various devices (for example, computers) may involve generation of signals (TEMPEST) that contain classified information. These signals can be intercepted with the help of special equipment.
Radio interference generators are designed to operate within active information protection systems (APS)enabling information security against data leaks through the TEMPEST channels by generating a broadband noise electromagnetic interference on the edge of the control zone. Such interference noises out the stray radiation of the protected item.

Noise generator, 0.01-1,800 MHz

Generator through the 220 V power grid with the frequency of 50 Hz (phase, neutral and ground) and to prevent unauthorized data retrieval through TEMPEST channels, 0.01-2,000 MHz.

Hardware and software complex for protection against TEMPEST, 0.009 to 1,000 MHz


Noise generator designed to generate and radiate a broadband high-frequency signal in the frequency band of up to 1 GHz
