ABSTRACT:
In a probe terminating apparatus, ground terminals, power supply terminals, and open terminals are provided on a print circuit board, and a ground potential applying terminal and a power supply voltage applying terminal are also provided on the print circuit board. In addition, a pull-down resistance apparatus is inserted to be connected between each of the ground terminals and the ground potential applying terminal, and a pull-up resistance apparatus is inserted to be connected between each of the power supply terminals and the power supply voltage applying terminal. Terminals of an evaluation microcomputer in an in-circuit emulator are connected to the ground terminals, the power supply terminals, and the open terminals by the connection of a probe and an IC socket, or connectors. The probe is connected to the terminals of the evaluation microcomputer, and the IC socket is connected to the ground, power supply and open terminals of the probe terminating apparatus.
