(一)载波机通讯设备1、312 载波机限幅器偏流值的优选一、问题的提出与分析:312载波机电路的振幅特性,不容易调到部颁标准,造成电路质量较低,影响通讯.我们配合整治设备工作,对限幅器偏流值,运用优选法,进行调整,取得了满意效果.试验方法:用10ΚΩ电位计调整并臂偏流为3.5ma,限幅不够,调整为2.5ma,限幅过早、运用0.618法在2.5～3.5ma之间进行优选.
(A) Carrier Communication Equipment 1,312 preferred carrier wave limiter bias value One, the problem raised and analyzed: 312 carrier circuit amplitude characteristics, not easily transferred to the ministerial standards, resulting in lower circuit quality, the impact Communication.We work with the remediation equipment, the limiter bias current value, the use of optimization method, to adjust, and achieved satisfactory results.Experiment method: 10KΩ potentiometer and the arm bias current is 3.5ma, the limit is not enough, adjusted to 2.5ma, Limitation of premature, the use of 0.618 method between 2.5 ~ 3.5ma preferred.
