Abstract
PURPOSE: To make it possible to shorten the length of a probe by providing a folded coaxial line, and a probe connected to the core at the folded point, and terminating both ends of the coaxial line with characteristic impedance of the coaxial line.
CONSTITUTION: A coaxial lines 6 is folded and the core and a probe 3 are connected to each other at this folded point, and a terminal resistance is mounted on the end of the coaxial line. The value of the terminal resistance is made equal to the characteristic impedance, whereby even at the end part of the line, multiple reflction of signal pulses can be prevented. By this procedure, the length of the probe can be reduced to about 1mm, and hence it is possible to obtain a probe most adapted to the measurement of the high-frequency characteristic.
