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.

LGS-501
LGS-501

Noise generator, 0.01-1,800 MHz

Where to buy?

LGS-501noise generator provides protection against data leaks through the TEMPEST channels by generating a broadband noise electromagnetic interference in the frequency band of 0.01-1,800 MHz.

The generator can be used based on two telescopic antennas and (or) on the outer antennas mounted as three or four loops of cable arranged along the perimeter of three mutually perpendicular planes.

LGS-501 is fed off of the AC circuit with the voltage of 220 V and frequency of 50 Hz. The device can be operated round the clock.
