Claim 0:
1. A testing head configured to verify the operation of a device under test integrated on a semiconductor wafer, the testing head comprising:
a plurality of contact elements, each including a body that extends between a first end portion and a second end portion, the plurality of contact elements being a buckling beam type; and
at least one guide including a plurality of guide holes configured to receive the contact elements,
wherein the at least one guide includes:
a first conductive portion that includes and electrically connects a first group of guide holes, of the plurality of guide holes, to each other and is configured to contact first contact elements, of the plurality of contact elements, the first contact elements being configured to carry a first type of signal; and
a second conductive portion that includes and electrically connects the holes of a second group of the guide holes, of the plurality of guide holes, to each other and is configured to contact second contact elements, of the plurality of contact elements, the second contact elements being configured to carry a second type of signal that is different from the first type of signal,

wherein the first conductive portion and the second conductive portion are formed on a first face of the at least one guide and are physically and electrically separated from each other by at least one non-conductive zone.
