The aim of the work is to develop and study the principle of operation tunable band noise generators (MGSH) of their characteristics, noise signal conditioner of a modular type, which provides controlling the bandwidth of the noise signal for use as a means setting radio noise. Through the formation and radiation in the surrounding space of electromagnetic fields of the energy spectrum in specified frequency ranges, with the possibility of changing the amplitude and bandwidth of the signal. To improve performance and make them more widely used in order to high-quality counteraction to unauthorized removal by intruders information on emission channels of spurious electromagnetic radiation (SEMI), it is necessary to create multichannel adaptive SLGNs. In the developed generators in each noisy channel, it is possible to provide power adjustment, generated noise signal and noise bandwidth control, which will improve the electromagnetic compatibility of such devices. For to ensure this, it is proposed to use a design concept based on on the use of controlled modules of noise sources with band-pass filters, which also allows you to get a noise signal uniform in amplitude.
