The noise generator for power supply, grounding and PEMI circuits "LGSh-513" is intended for use in order to protect information containing data constituting a state secret and other information with limited access, processed by technical means and systems, from leakage due to side electromagnetic radiation and interference by forming masking noise-like interference.
The "LGSh-513" product complies with: - type "A" - means of active protection of information from leakage due to side electromagnetic radiation; - type "B" - means of active protection of information from leakage due to interference of an information signal on conductors, including on grounding and power supply circuits, conductive lines and engineering and technical communications extending beyond the controlled area. The LGSh-513 product complies with the requirements of the document “Requirements for Active Information Protection Equipment against Leakage Due to Spurious Electromagnetic Radiation and Interference” (FSTEC of Russia, 2014) – protection class 2. The LGSh-513 product is equipped with a visual system for indicating normal operation and a visual and sound system for indicating emergency operation (failure).
The LGSh-513 product is equipped with a time-of-use counter that records and displays in hours and minutes the total operating time of the Product in the masking interference generation mode.
The design of the LGSh-513 product ensures protection of the output noise signal level adjustment organs from unauthorized changes and detection of unauthorized access to them.
The LGSh-513 product has the ability to connect a wired remote control and monitoring system, which can be the “Web” hardware and software complex.
