Noise generator with operational control SPECTRAL DENSITY OUTPUT

摘要

The invention relates to the technique of counter commercial (industrial) espionage and management intelligence for technical side channels of information leakage due to stray electromagnetic radiation and interference. To a DC power source connected to a broadband amplifier and a chain of serially connected adjustable resistor, inductor and the blocking of the zener diode. Blocking capacitor connected between the input potential of the amplifier output and the common terminal of the blocking choke and zener diode. An adjustable resistor is arranged to regulate the spectral density in the operating frequency band of 10 kHz to 3 GHz, and the power - with the possibility of transmission of signals in said working frequency band, including the operation of 50 - or 75 - ohm microwave paths. The utility model enables generation of noise with a spectral density of the output signal, adjustable in operating frequency band of 10 kHz to 3 GHz. In this case, due to the possibility to carry out operational control of the current through the zener diode, improved accuracy is achieved job generated noise spectral density ensuring its uniformity. 2 ZP f-ly. 2 yl.
