Patent ID: 6937040

Claim:
A probe module electrically coupled to a terminal of a device under test for sending and/or receiving a signal to and/or from said device under test, comprising: a first substrate; a probe pin provided on said first substrate to be in contact with said terminal of said device under test; a first signal transmission pattern formed on said first substrate, said first signal transmission pattern being electrically coupled to said probe pin, with a gap formed at said first signal transmission pattern not to transmit any electric signal; a first switch means for short-circuiting or open-circuiting said gap of said first signal transmission pattern; a second signal transmission pattern formed on said first substrate, said second signal transmission pattern being electrically coupled to said probe pin, with a gap formed at said second signal transmission pattern not to transmit any electric signal; and a second switch means for short-circuiting or open-circuiting said gap of said second signal transmission pattern, wherein said probe pin is coupled to a joining point of said first and second signal transmission patterns, and wherein the first switch means and the second switch means are controlled such that a first signal on the first transmission pattern does not interfere with a second signal on the second transmission pattern.
