Abstract:
1. An impedance measurement system that measures an impedance of a power source of an electronic apparatus, the impedance measurement system comprising: an input device configured to input information of the electronic apparatus and a measurement condition; a measurement operation program device configured to select a predetermined program that operates the electronic apparatus based on the information of the electronic apparatus and the measurement condition input from the input device and to execute the selected predetermined program by the electronic apparatus; a voltage measurement device configured to measure a voltage variation of the power source of the electronic apparatus while the predetermined program is executed by the measurement operation program device; a wave form calculating device configured to calculate frequency characteristics of voltage of the power source from the voltage variation of the power source measured by the voltage measurement device; an impedance calculating device configured to calculate an impedance from the frequency characteristics of the voltage of the power source calculated by the wave form calculating device and current characteristics of current generated when the predetermined program is executed by the measurement operation program device; and an output device configured to output the impedance calculated by the impedance calculating device, wherein the electronic apparatus comprises a Large-Scale Integration (LSI) board operated by the selected predetermined program.
