光线示波器振子的选用

Oscillator Selection for Loop Oscillograph

为了准确地测量记录各种被测信号，应当正确地选用振子的固有频率和阻尼．适当地选取被测信号的大小，保持信号源内阻R1与振子的内阻rg相匹配，同时要正确地调整光点位置，以减小圆弧误差。

In order to accurately measure and recorder various measured signals, we ought tocorrectly select the nature frequency, damping of oscillators and magnitude of the measured signalsource matching with internal resistance rg of oscil1ator. We also properly adjust the posit1on of thelight dots, so that the arc errors are reduced.
