声纳前放模块幅度增益检测电路设计

摘要

Amplitude gain is one of the most important performance indexes of pre-amplifier module .Amplitude gain is important for a sonar performance whether it is normal or not .In order to improve the detection efficiency of the amplitude gain of the pre-amplifier module ,a measurement circuit is designed based on modern electronic measurement technology and micro controller .The detection circuit can automatically realize the measurement of the amplitude gain of the pre-amplifier module and the measurement accuracy can meet the requirements ,so as to shorten the testing time and improve the efficiency of equipment maintenance and support .%幅度增益是声纳前置放大模块最重要的性能指标之一，其正常与否对声纳装备整体性能至关重要。为了提高前放模块幅度增益的检测效率，基于现代电子测量技术和微控制器设计了一种幅度增益测量电路。该检测电路能够自动实现前放模块的幅度增益技术指标的检测且测量精度满足要求，从而缩短测试诊断时间，提高了装备维修保障效率。
