The circuit and method for obtaining equal measuring accuracy and response speed in a wider frequency signal range are discussed in this paper.
本文探求在较大的被测频率信号范围内获得相同的测量精度与响应速度的测量方法及电路。
Measuring for the beat error (frequency error) : Numerical display in milliseconds. Resolution is 0.1 milliseconds; the measuring range is 0-9.9 ms.
偏振(频率错误)测量：数值以毫秒显示。分辨率是0.1毫秒，测量范围是0—9.9毫秒。
When traditional method is used for measurement at low frequency range, measuring precision can not be guaranteed and measuring is time-consuming.
传统的频率特性测量方法，在低频时，测量精度较差，且非常费时。
