Frequency response analyzer is used to measure the amplitude-frequencycharacteristic and phase-frequencycharacteristic of the networks.
频率特性分析仪用于测试网络的幅频和相频特性。

The position of knee point of Phase-frequencycharacteristic mean value curve is invariant, but the kurtosis of the curve near the knee point decreases.
刚度与质量参数随机时相频特性均值曲线的拐点位置不变,只是拐点附近曲线陡峭度减小。

It can measure the magnitude characteristic, phasecharacteristic and limiting frequency of a system.
