信号完整性是指信号在传输路径上的质量,是信号在电路中能以正确的时序和电压作出响应的能力。信号完整性验证会用到很多专业的仪器,其中最常用到的是示波器,它能将肉眼看不到的电信号变换成看得见的图像,便于我们研究和分析电信号的变化过程。下面是PCIE信号验证及优化的例子。PCIE信号验证及优化PCIE是服务器产品中重要的扩展接口,很多外接板卡都是通过PCIE接口扩展的,如RAID卡、SAS卡、网卡等。PCIE信号质量会直接影响到外接板卡的性能、稳定性及可靠性。
Signal integrity is the quality of a signal on the transmission path and is the ability of the signal to respond in the circuit at the right timing and voltage. Signal integrity verification will use a lot of professional equipment, the most commonly used is the oscilloscope, it can not see the naked eye can transform the electrical signals into visible images, allowing us to study and analyze the changing process of electrical signals. The following is an example of PCIE signal verification and optimization. PCIE signal verification and optimization PCIE is an important expansion of the server interface, a lot of external boards are extended through the PCIE interface, such as RAID cards, SAS cards, network cards and so on. PCIE signal quality will directly affect the external board performance, stability and reliability.
