一、工作原理该仪器的基本结构如图1所示,电原理图如图2所示。时基脉冲发生器由F_1、F_2、石英晶体、IC_1、IC_2等组成。其中F_1、C_6、C_7及石英晶体等构成时基振荡器,产生 100kHz时基脉冲,然后经F_2加到IC_1、IC_2进行分频,从而获得周期分别为0.01 ms、0.1ms、1ms、10ms的标准时基脉冲,不同量程时由 K_1进行选择。控制部分由IC_3、F_3、F_4、K_2、K_3等组成,用来决定
First, the working principle The basic structure of the instrument shown in Figure 1, the electrical schematic shown in Figure 2. Time base pulse generator by F_1, F_2, quartz crystal, IC_1, IC_2 and other components. The F_1, C_6, C_7 and quartz crystals form a time-base oscillator and generate a 100 kHz time-base pulse, which is then frequency-divided by IC_2 and IC_2 to obtain standard periods of 0.01 ms, 0.1 ms, 1 ms, and 10 ms, respectively Base pulse, different range by K_1 to choose. Control by the IC_3, F_3, F_4, K_2, K_3 and other components used to decide
