Abstract

PURPOSE:To ensure an easy detection for the crosstalk attenuation quantity to the optional standard characteristics over the entire necessary band by connecting the input and output terminals of the amplifying part provided to the measurement unit between the crosstalk attenuation objects to be measured and thus detecting the oscillation at the amplifying part. CONSTITUTION:Amplifying part 31 provided within measurement unit 29 which detects the worst value of the crosstalk attenuation quantity to the crosstalk standard at the frequency band, and input and output terminals 32 and 33 of part 31 are connected between the crosstalk attenuation objects with level meter 34 connected to the output side. The gain of part 31 can be controlled by the signal sent from gain control terminal 35 of part 31, and thus the gain characteristics of part 31 is controlled identical to the necessary crosstalk attenuation characteristics. And the oscillation of part 31 via the crosstalk attenuation object connected to terminal 32 and 33 is detected by meter 34, thus detecting the crosstalk attenuation quantity to the optional standard characteristics of the entire band.
