PURPOSE: A PCI bus type system characteristics measurement system is provided to adjust parameters which it is possible to simulate, and to test a critical environment and a characteristics limit at an initial stage so that it can enhance a quality. CONSTITUTION: The system comprises an interface card(30), a controller(40), a display(50) and a setting module(60). The interface card(30) can be inserted into a PCI slot(20). The controller(40), installed in the interface card(30), reads or writes various offset value at a register of a main board(10). The display(50) displays the values read from the controller(40). The setting module(60) sets a register value of the main board(10) via the controller(40). The characteristics measurement system is inserted in the PCI slot(20), the controller reads the data stored in the register of the main board(10), and displays the read data on a screen. Then the user watches the offset value displayed on the screen, and changes the register value of the main board(10) via the setting module(60) if it is necessary to change the functions of peripherals.
