electronic attenuator meaning in Chinese

电子式衰减器
电子衰减器

Supervisor point is behind the postposition of power amplifier , optic signals coming from a tap of 99 : 1 enter into optic spectrum scan module , then the power levels which have been calculated by iterative algorithmic are sent to power control module to guide a set of tunable electronic attenuators
此方案将监测点放在后置功率放大器的后面，从分束器中分出99 ： 1的光进入光频谱扫描模块，传给功率控制模块的光功率值经过选代算法后计算出均衡后的功率值送到功率控制模块的控制中心去调节电可调节衰减器。
