It can measure the magnitude characteristic, phase characteristic and limiting frequency of a system.
它能直观的测试一个系统的幅频特性、相频特性和截止频率。
Because it is related to the magnitude of noise RMS voltage, the frequency characteristic of circuit and the power spectrum of noise source, the accuracy of measurement is quite low.
但由于与噪声电压的大小，网络频率特性及噪声源功率谱形式有关，故测量准确度较低。
The seismicity of this segment does not follow the linear frequency-magnitude relationship described by Gutenberg and Richter because it is controlled by the characteristic earthquake model.
该段的地震活动属特征地震模式，不服从古登堡·里克特的线性震级频度关系。
