用模拟开关扩展示波器的功能

Expansion of Oscilloscope Functions with Analog Switches

本文主要说明如何用模拟开关扩展示波器的功能,及将单踪示波器变为多踪示波器。用单踪示波器可以同时测试四路及以上的信号波形。有效的扩展了现有示波器的功能。

The paper mainly deals with the approaches of expanding the oscilloscope functions with analog switches, and the ways in upgrading the single signal oscilloscope into multi - signal oscilloscope. Therefore the single signal oscilloscope can be used to test 4 or more route of signals and effectively expand the existing oscilloscope functions.
