本文讨论航天飞机数据总线结构的分析和性能验证。讨论了拟定字错误率模式的分析方法。并给出了典型结果。为验证这些分析结果,证实多路传输系统的性能,用多个MLA和航天飞机数据总线电缆构造了几种航天飞机数据总线,并成了包括WER和波型保真度的测试。同时取得了字错误率数据,这一数据随上升时间、内部阀电压。rms(有效值)噪音电平、信、补偿,温度和信号幅值这样一些参数的改变而变化。
This article discusses the space shuttle data bus structure analysis and performance verification. Discussed the formulation of the word error rate analysis method. And gives the typical result. To verify the results of these analyzes, demonstrate the performance of the multiplex transmission system, several Space Shuttle data buses were constructed with multiple MLA and Shuttle data bus cables and became tests that included WER and wave fidelity. At the same time made the word error rate data, this data with the rise time, the internal valve voltage. rms (rms) The noise level, signal, offset, temperature, and signal amplitude change in some of these parameters.
