Patent ID: 8081008

Claim:
A computer system for testing a characteristic impedance of at least one electronic component of an electronic device, the computer system being connected to a control computer and a time domain reflectometer (TDR) through a switch, and the computer system being further connected to a mechanical arm, the computer system comprising: a parameter setting module operable to set test parameters of the at least one electronic component on the electronic device, the test parameters comprising coordinates of the at least one electronic component, a standard characteristic impedance of the at least one electronic component, and a preset storing path to store measured data of the at least one electronic component; a parameter obtaining module operable to read the coordinates of the at least one electronic component; a command sending module operable to send a positioning command to the control computer according to the coordinates of the at least one electronic component on the electronic device, so as to drive a probe holder of the mechanical arm to position probes of the TDR to a position of the at least one electronic component on the electronic device; the command sending module further operable to determine if the probes are positioned accurately; a testing module operable to read measured data of the characteristic impedance of the at least one electronic component collected by the TDR, if the probes are positioned accurately; the testing module further operable to compare the measured data of the at least one electronic component with the standard characteristic impedance of the at least one electronic component, so as to determine if the measured data of the at least one electronic component is acceptable; the testing module further operable to generate a test report for storing the measured data and the determined result, and store the test report according to the preset storing path; and at least one processor to execute the parameter setting module, the parameter obtaining module, the command sending module, and the testing module.
