A probe module electrically coupled to a terminal of a device under test for
sending
and/or receiving a signal to and/or from the device under test, includes a first
substrate, a probe pin provided on the first substrate to be in contact with the
terminal of the device under test, a first signal transmission pattern formed on
the first substrate, the first signal transmission pattern being electrically coupled
to the probe pin, with a gap formed at the first signal transmission pattern not
to transmit any electric signal, and a for short-circuiting or open-circuiting
the gap of the first signal transmission pattern.
