FIELD: radio engineering, communication.
SUBSTANCE: device comprises first and second spectrum analysers and a correlation coefficient meter, the output of which is the output of the device, the first and second test inputs of which are the inputs of the first and second spectrum analysers, respectively. The output of the first spectrum analyser is connected to the first input of the correlation coefficient meter. Furthermore, the device includes a multiplier unit and an amplitude-frequency characteristic setting device, the output of which is connected to the first input of the multiplier unit, the second input of which is connected to the output of the second spectrum analyser, the output of which is connected to the second input of the correlation coefficient meter.
EFFECT: broader functional capabilities by enabling estimation of frequency distortions in radio circuits with a non-uniform amplitude-frequency characteristic in the operating frequency range.
