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。
Static deflected spot is one of the important ways to ensure the accuracy and reliability of spot testing. This article introduces a high stability pulse deflection amplifier, which is characterized by the line, frame deflection coils of different pulse width and variable amplitude of the drive current, the deflection coil in the pulse static deflection state. Tests and experiments show that this pulse deflection amplifier is a very effective measurement of static deflection light spot.
