Claim 21:
22. 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 comprising a body that extends between a first end portion and a second end portion,
a first guide including a first plurality of guide holes apt to receive the contact elements, and
a second guide spaced apart from the first guide, the second guide including a second plurality of guide holes apt to receive the contact elements, the contact elements being configured to extend through the first plurality of guide holes and the second plurality of guide holes,
wherein the first guide comprises:
a first conductive portion that includes and electrically connects a first group of guide holes, of the first 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 a second group of guide holes, of the first 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 first guide and are physically and electrically separated from each other by at least one non-conductive zone.
