摘要
示波器是实验室中的常用仪器,多数型号的示波器只给出用于自检的标准方波信号(1000Hz),为满足某些实验要求,作者尝试将其电源线路进行部分改动,使其输出一个50Hz的正弦波。
Oscillograph is a common instrument used in laboratory. Majority types of oscillograph provide just the standard (1000Hz )square wave signal used for self-inspection. To meet the need of some experiments, we have improved part of the circuit, as a result, it gives a 50 Hz sine signal.
