FIELD: radio-electric measurements.
SUBSTANCE: device has multiplexer, filtering block, analog-digital converter, square-ware generator, two accumulating adders, functional converter, performing in simplest case operations of division and square root, as well as control block and white noise generator. Device uses random process with broad range as test signal and allows to measure amplification coefficient concurrently in certain range of frequencies. Products of nonlinear distortions are taken in consideration, which accompany operation of real amplifiers and which influence shape of output signal as well as its level.
EFFECT: higher precision.
