摘要

本文介绍了一种利用频率合成器产生的正弦信号测量和分选射频线圈的简单方法。将正弦信号应用到由电感未知的线圈和电容已知值组成的电路中。通过测量谐振频率和包络线的电平，可以计算出电感和质量因数。当输入信号的频率逐级变化时，会产生改变结果的瞬态效应。本文着眼于导致消除这些影响的条件。

Method of measuring and sorting coils using a frequency synthesizer

The paper presents a simple procedure used for measuring and sorting RF coils using a sinusoidal signal generated by a frequency synthesizer. The sinusoidal signal is applied to a circuit made up of coils with unknown inductance and a capacitor with known value. By measuring the resonance frequency and the level of the envelope, one can calculate the inductance and the quality factor. As the frequency of the input signal varies step by step, there occur transient regime effects which alter the results. The paper looks at the conditions which lead to the elimination of these effects.
