Patent number: 8339121Abstract: An oscillograph can identify signals of a serial data bus. The signal identifying method triggers communication channels of the oscillograph, measures a rise time and a fall time for each captured signal, and sets a sender terminal (ST) and a receiver terminal (RT) for each of the captured signals according to the measured results. The signal identifying method determines the ST and RT for each of the captured signals after the oscillograph is triggered. If the determined ST of each of the acquired signals is identical to the set ST and the determined RT of the each of the acquired signals is identical with the set RT, the signal identifying process is completed and a report is generated to record the signal identifying result.Type: GrantFiled: December 23, 2009Date of Patent: December 25, 2012Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Wang-Ding Su, Jui-Hsiung Ho
