Abstract: In a low voltage differential signal (LVDS) timing test system and method, a clock signal waveform and a data signal waveform are obtained. Clock cycles are selected from the clock signal waveform. Data bits transmitted within the selected clock cycles are identified from the data signal waveform. Accordingly, bit positions of the data bits are determined.

Abstract: A test system includes a main selector, a first and a second switching connectors, a first and a second sub-selectors, and a processor. The main selector includes a number of first switches, a number of first contacts, and a number of second contacts. Each sub-selector includes a second switch, a third contact, and a fourth contact. The processor sends a first instruction and a second instruction to correspondingly control the main selector and a selected sub-selector.

Abstract: 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.

Abstract: 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.

Abstract: An electronic device includes a video signal detection system to measure video signals. A measurement method can measure the video signals by using the electronic device. The measurement method sets measurement parameters that are used to measure video signals. Furthermore, the measurement method generates measurement results that each corresponds to a video signal transmission channel between the electronic device and a video signal processing device. In addition, the measurement method generates a measurement report according to all the measurement results.

Abstract: 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.
