前言：USB3.0测试,测试，usb3.0 一致性测试,usb3.0测试规范,usb3.0 线材质量 测试
USB 3.0线缆测试包括：
1.阻抗(lmpedance)
2.差分对内时间偏差(Intra-pair Skew)
3.差分回损(Differential return loss)
4.差分插入损耗(Differential insertion loss)
5.差分近端串扰(Differential Near-end crosstalk)
6.差分共模转换(Differential to CM conversion)
7.USB 2.0和USB 3.0间差分串扰(Differential Crossalk between USB 2.0 and USB 3.0 pair)
