示波器水平放大器的主要任务是放大线性扫描电压,这放大了的电压被加到容性负载水平偏转板上,由于水平偏转板的偏转灵敏度较低,屏幕的横向尺寸较大,这就决定了水平放大器必须有比垂直放大器大得多的输出幅度。所有这些,使水平放大器有着不同于其它放大器的特点。下面简要地阐述设计过程中应考虑的一些基本原则。因限于水平,可能有些观点是错误的,请同志们予以指正。
The main task of an oscilloscope’s horizontal amplifier is to amplify the linear sweep voltage. The amplified voltage is applied to the capacitive load deflection plate. Because of the low deflection sensitivity of the horizontal deflection plate, the horizontal size of the screen is larger, which determines the level The amplifier must have a much larger output amplitude than the vertical amplifier. All of this makes horizontal amplifiers different from other amplifiers. The following briefly describes some of the basic principles that should be considered in the design process. Due to the limited level, some opinions may be wrong, please comrades correct it.
