Computer GRQ-03C new product features
With the wide application of the computer, in governmentand army departments, banking system, business groups extensive use of computers to handle classified information, the classified computer work will produce large amounts of electromagnetic radiation, and carry are dealing with classified information, such as unprotected, the corresponding reception device can receive a reduction of classified information on a computer screen, which will directly lead to the disclosure of secret information, causing heavy losses to the party and the country, the army and the business community. "GRQ-03C computer related interference device" is a kind of information security and security product which is specially designed to solve the problem of computer radiation leak. Its advanced technology, strong anti reduction ability, good protection effect, small size, light weight, stable and reliable performance, easy installation, can effectively prevent the computer from the leakage of electromagnetic radiation, the product through the Chinese people's Liberation Army information security evaluation and Certification Center, military B level certification (currently the highest level).
1 using the related interference technology to make the interference signal and the computer radiation has a good correlation, the use of a single white noise as the interference signal is easy to be related to the suppression of the weakness of the relevant and non relevant to steal computer radiation conditions, greatly improving the difficulty of reading computer information.
Space. The random number encryption techniques, the classified computer electromagnetic radiation signal is disturbed, even if that eavesdropper receives the electromagnetic radiation signals is also very difficult V signal carried by the real information.
3. The spatial random encryption, interference and noise confused covering a variety of interference at the same time to protected the computer radiation information of multiple interference, to steal that eavesdropping classified information more difficult or even impossible.
4 "GRQ-03C computer related interference", the interference signal can automatically track the change of computer display mode, automatically adapt to different modes of work of the display terminal, so that the time domain is the same, the frequency domain, the ability to resist video receiving.
5. The display pattern recognition and synchronization control technology so that the jammer only row, field synchronization signal is during the scanning process emission signal interference, in during the inverse process without signal interference, both the effective protection of the classified information and shorten the time for transmitting signal interference, effectively reduce the radiation on the human body.
6.USB interface power supply, no external power supply.
7 no need to install the software, easy to install and use.
8 compatible with desktop and notebook PC.

The new method of using computer GRQ-03C
1 when the "GRQ-03C computer related interference" and the protection of computer connection, the video signal cable plug and plug in the video signal cable plug and plug in the special video adapter cable DB15 head, the special video adapter cable, the other DB15 head inserted in the computer graphics card, special video adapter cable USB head inserted in the VGA interface, and then connected to the computer USB interface and interfering with USB.

2 "GRQ-03C computer related interference device" and the protection of computer distance is generally about 0.5 meters.
