Noise signal generator MARS-TZO-4-2
The MARS-TZO-4-2 noise generator is designed to create a noise signal within the frequency range from 180 to 5600 Hz as a part of the technical means of information protection from leakage through the acoustic and vibro-acoustic channels. The generator has two outputs: “OUTPUT 1” and “OUTPUT 2” – for connecting acoustic emitters and vibration emitters.
The generator provides a noise signal level output (3.5 + 0.2) within the frequency band from 180 to 5600Hz under a load of 4 ohms. The distribution of the noise spectrum corresponds to pink noise with a voltage drop in 1 dB in the three-octave bands. The deviation of the spectrum distribution in the tertiary bands – not less than +3 dB relative to the band with an average frequency of 1 kHz.
- The depth of noise signal levels adjustment outputs – at least 20 dB.
- The generator provides output voltage indication according to 10-segment indicator.
- The generator provides noise level control indication while using the sensor – accelerometer MVIR.467278.002-01.
- Supply voltage – 100 to 240 of alternating current with a frequency of 50Hz. Power consumption – no more than 40 VA.
- The generator provides an external load power with a voltage of 5V and current of 0.15A.
For electrical safety, the generator meets the requirements of class 1 according to GOST 12.2.007.0-75. The supply circuit isolation of the product withstands voltage of 1000V sinusoidal with a frequency of 50Hz without breakdown and surface overlap.
