Patent number: 8370685Abstract: An electronic device includes a serial signal test system to test serial signals generated by a serial signal generator. A test method tests serial signals using the electronic device. The test method sets test parameters that tests serial signals. Furthermore, the test method identifies an error bit from coded bits of each of the serial signals, and identifies abnormal attribute data of each of the serial signals. In addition, the test method generates a test report according to all identified error bits and abnormal attribute data.Type: GrantFiled: April 14, 2010Date of Patent: February 5, 2013Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Wang-Ding Su, Jui-Hsiung Ho, Yung-Cheng Hung

Patent number: 8219338Abstract: A testing system for bus parameters includes a wave displaying unit and a control module connected to the wave displaying unit. The control module includes a decode unit, a testing unit connected to the decode unit, and an output unit connected to the testing unit. The decode unit is connected to the wave displaying unit. The wave displaying unit is configured for receiving an electronic signal from a bus to be tested. The decode unit is configured for decoding the electronic signal to determine if the electronic signal is valid. The testing unit tests parameters of the bus. The output unit displays testing results for the parameters.Type: GrantFiled: October 29, 2008Date of Patent: July 10, 2012Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Wang-Ding Su, Yung-Cheng Hung, Hsien-Chuan Liang, Po-Kai Huang, Mi-Wen Tsai, Chi-Ren Kuo

Publication number: 20110057643Abstract: A oscillograph and a signal integrity test method are provided. The oscillograph measures a serial data bus to obtain captured signals transmitted by each communication channel of the oscillograph. By identifying a time sequence for the captured signals transmitted by each communication channel, a test signal is determined. The oscillograph measures a clock frequency of the test signal, sampling a part of the test signal, and testing the part according to pre-set test items. If a predetermined number of samples of the test signal is tested, the oscillograph constitutes a completed signal integrity test of the serial data bus and a test report is generated.Type: ApplicationFiled: December 13, 2009Publication date: March 10, 2011Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: WANG-DING SU, JUI-HSIUNG HO, YUNG-CHENG HUNG
