The noise signal generator Ya5Kh-268 (Ya5Kh 268; Ya5Kh268; Ya5Kh/268)
Noise generator Ya5Kh-268 - test oscillator, the output of which is the realization of a random process with controlled statistical properties.
Generators Ya5Kh-268 is used in the measurement of the maximum sensitivity of the amplifier noise figure radios, noise studies of various electronic, automated and electronic systems or individual components. Also Ya5Kh-268 is used when removing the frequency characteristics of the electro-acoustic devices, calibration of instruments for measuring the probability characteristics of random processes, etc.
Structural features Ya5Kh-268
The main unit of the circuit noise generator Ya5Kh-268 is an oscillator. Its signals have uniform power spectral density across the desired bandwidth.
As a model for the source of the noise generator Ya5Kh-268 is a hot wire resistor, the effective voltage which is calculated by the formula:
U2 = 4kTRΔfe,
