<P>PROBLEM TO BE SOLVED: To provide a testing apparatus capable of easily extracting a simulation model of a transmission line. <P>SOLUTION: An I/O pin P<SB POS="POST">I/O</SB>is connected to a DUT via a transmission line 20. A driver DR generates a test signal to be supplied to the DUT. A driver-side switch 22 and an output resistance Ro are provided in series between the driver and the I/O pin P<SB POS="POST">I/O</SB>. A comparator CP, whose input terminal is connected to the IO pin P<SB POS="POST">I/O</SB>, determines the level of a signal from the DUT. A short switch 34 is provided between the I/O pin P<SB POS="POST">I/O</SB>and a ground terminal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
