Abstract
A probe for measuring signals with a narrow contact pitch comprises an end section having a main tip member and a sub-tip member, each of which passes through one of two holes in a housing. The sub-tip member is electrically connected to the housing and the main-tip member is insulated from the housing by an insulation member. The sub-tip member is pivotally connected to the housing. The subtip member is asymmetric with respect to the pivot and therefore, its sharpened end can trace a circular orbit when the sub-tip member turns on its pivot. The distance between the two end sections of these tip members (that is, the contact pitch) can be set to a desired length by positioning sub-tip sharpened end section to any point on this orbit.
Claims18
A probe for measuring signals comprising:
- a coaxial probe body for conveying signals between a device under test and an electronic measuring unit;
- and
- an end section, electrically and coaxially coupled to said probe body, said end section comprising:
- a housing having portions defining a first hole and a second hole;
- a first tip member inserted in said first hole, said first tip member and electrically insulated from said housing for conveying a first signal between said device under test and said measuring instrument;
- and
- a second tip member inserted in the second hole and electrically coupled to said housing, said second tip member having a first end rotationally held therein and a second end having an asymmetric shape with respect to its rotation, said second tip member electrically insulated from the first tip member and for conveying a second signal between said device under test and said measuring instrument;
- wherein the distance between a sharpened end of the first tip member and said second end of the second tip member is determined by rotating said second tip member to a specific position.
