由电子管放大器、扫描振荡器、阴极射线管等组成。将电压加在电极板上，极板间形成相应的变化电场，使进入这变化电场的电子运动情况相应地随时间变化，最后把电子运动的轨迹用荧光屏显示出来。被测信号经过探头和前端放大器以及归一化后转换成ADC可以接受的电压范围，采样保持电路按固定的采样率将信号分割成一个个独立的采样电平，ADC将这些电平转化为数字的采样点，这些数字的采样点保存在采集存储器里送显示和测量分析。
It is composed of vacuum tube amplifier, scanning oscillator and cathode ray tube. The voltage is added to the electrode plate, and the corresponding changing electric field is formed between the plates, so that the movement of the electrons into the changing electric field changes correspondingly with time. Finally, the trajectory of the electron movement is displayed with a fluorescent screen. The measured signal is converted into a voltage range acceptable to ADC through the probe and front-end amplifier and normalization. The sampling and holding circuit divides the signal into independent sampling levels according to a fixed sampling rate. ADC converts these levels into digital sampling points, which are stored in the acquisition memory for display, measurement and analysis.
