The noise generator "LGSh-516STAF" 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 product "LGSh-516STAF" corresponds to: - type "A" of means of active protection of information from leakage due to side electromagnetic radiation; - type "B" of 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 zone. The product "LGSh-516STAF" corresponds to protection class 2. The LGSh-516STAF product complies with the requirements of the document “Requirements for Active Information Protection Means from Leakage Due to Spurious Electromagnetic Radiation and Interference” (FSTEC of Russia, 2014), taking into account the changes introduced by the order of the FSTEC of Russia No. 028 dated November 28, 2019. The LGSh-516STAF product is intended for use in designated areas up to and including category 2.
The LGSh-516STAF product has 5 levels of output noise signal adjustment. The product is equipped with a visual system for indicating normal operation and a visual and sound system for indicating emergency mode (failure). The product is equipped with a time meter 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 meter eliminates the possibility of unauthorized changes to its readings.
