On the bench, you can measure your converter's rmsnoise by acquiring a few hundred samples of a dc-input signal.
在这个基础上，通过获取上百次直流输入信号的采样，来测量转换器的均方根噪声。

A simple and practical analytical model of fluctuation error (RMS miss distance due to glint noise) of the homing guidance System, is then obtained to calculate guidance accuracy.
Because it is related to the magnitude of noiseRMS voltage, the frequency characteristic of circuit and the power spectrum of noise source, the accuracy of measurement is quite low.
