20140365826 | AUTOMATIC TESTING METHOD AND SYSTEM FOR ELECTRONIC DEVICES - An automatically testing system includes a control device and a testing instrument. The control device initializes a first Input/Output (I/O) interface, and the testing instrument initializes a second I/O interface and a third I/O interface. The testing instrument receives test parameters of an electronic device to generate test data and transmits the test data to the control device. The control device receives the test data and transmits the test data to a data analyzing unit. The data analyzing unit analyzes the test data and determines whether the test data are valid. The data analyzing unit transmits the test data which are determined to be valid to a test result display unit to display the test data. The data analyzing unit stores the test data which are determined to be valid in a data storage unit, and the control device determines whether the testing instrument has completed testing the electronic device. | 12-11-2014 |
