摘　　要：　静态偏转光点是确保光点测试的准确性和可靠性的重要方法之一。本文介绍一种高稳定性的脉冲偏转放大器,其特点是分别提供行、帧偏转线圈不同脉宽且可变幅度的驱动电流,使偏转线圈工作于脉冲静态偏转状态。测试实验表明这种脉冲偏转放大器是一种静态偏转光点的十分有效的测量设备。The pulsed static deflection spot is one of the very important methods in which the spot measurement can make sure of exactness and reliability. This paper introduces a kind of the pulsed deflection amplifier with much better stability. Its distinguished feature is to supply the pulsed driving current with different duration and flexible amplitude toward the line and frame deflection coils. Thus the deflection coils work at the pulsed static deflection state. The experiments have demonstrated that this kind of the pulsed deflection amplifier is an effective measuring equipment for the pulsed static deflection spot.
