摘要
分析了网络协议测试仪的串行通信接口功能,设计了一种可编程多协议串行接口电路.该电路以SP505多协议串行通信收发器和ispLSI2064E可编程逻辑器件为核心,通过CPU在线设定工作方式和接口协议.电路成功地应用于WPT-2000广域网协议测试仪,经美国安捷伦的J2300-E ADVISOR协议测试仪测试,功能完全满足广域网络测试要求.
The function of serial communication port in protocol tester was analyzed and a programmable multi-protocol serial communication interface circuit was designed.The circuit was mainly composed of sp505 multi-protocol serial transceivers and programmable logic device,and the work mode and serial interface protocol can easily be configured by CPU on line.It has been applied to WPT-2000 WAN protocol tester and the function can meet the demand of the tester through testing by J2300-E ADVISOR.
