我所高12路载波机曾使用单孔记忆磁芯导频控制电路.因该电路比较复杂,调测和维护比较困难,同时某些元件也不好解决,后决定采用场效应管控制电路.本导频控制器参照505厂电路,在试制中发现该电路调节电位器W_1输出电压变化不灵敏,不便调节输出电压,因而对扩张放大部分作了修改.另外告警电路参考了本所的单孔记忆磁芯导频控制电路的相应部分,并根据本导频控制器的不同特点和材料来源作了一些修改.实际测试结果表明,记忆性能方面本控制器比本所生产的单孔记忆磁芯控制要好些,其他指标基本相同.
I am using a high carrier 12-channel single-hole memory core pilot control circuit has been used because of the complexity of the circuit, commissioning and maintenance more difficult, while some of the components are not good to solve, after the decision to use FET control circuit. The pilot controller reference 505 plant circuit, found in the trial of the circuit to adjust the potentiometer W_1 output voltage change insensitive, inconvenient to adjust the output voltage, thus expanding the enlarged part made a modification of another alarm circuit reference to the single hole Memory core pilot control circuit of the corresponding part, and according to the pilot controller of different characteristics and material sources made some changes.The actual test results show that the memory performance of the controller than the production of single-hole memory core Control is better, other indicators are basically the same.
