基于音频控制电路测试中PLC技术和模拟测试系统的应用

摘要

传统的音频控制电路测试所采用的系统是一种数模混合测试，此系统涉及模拟信号测试与数字信号测试两个方面，频率覆盖了从Hz到上GHz的范围，但缺乏结构化的可测试性设计，测试时间长也较为昂贵。本文研究引入全新的音频控制电路测试方案，是基于单片机的基础上，利用单片机功能强、集成度高、可靠性高及编程开发灵活等特点，并采用PLC技术和模拟测试系统等方式测试音频控制电路，进一步加深了对模拟电路测试系统的利用率。%Conventional audio control circuit used in the test system is a digital-analog hybrid test, this test system involves the analog signal and digital signal test two aspects,covering frequencies from a few Hz to the GHz range,but the lack of structure of design for testability,test for a long time also more expensive.This paper introduces a new audio control circuit test program is based on single-chip based on the use of single-chip features high integration,high reliability and flexible features programming development and use of PLC technology and simulation test system to test audio controls,etc.circuit, further deepened the utilization of analog circuit test systems.
