Internal Loopback Test 内部回路测试
Additional features with the SP505 include internal loopback that can be initiated in either single-ended or differential modes.
SP505还包括内部回送在内的一些其它特性，内部回送可以在单端或差分模式被启动。
While in loopback mode, driver outputs are internally connected to receiver inputs creating an internal signal path convenient for diagnostic testing.
在回送模式中，驱动器输出在内部与接收器输入相连，建立一个内部信号通路以方便诊断测试。
