Claim 14:
15. 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, each contact element being a pogo pin, the body including:
a casing having a first surface and a second surface; and
an elastic member, in the casing, having a first end connected to the first end portion of the contact element and a second end connected to the second end portion of the contact element;

at least one guide including a plurality of guide holes configured to house the contact elements,
wherein the at least one guide comprises:
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 corresponding first contact elements, of the plurality of contact elements, 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 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 to the first type of signal,
wherein the first conductive portion and the second conductive portion are 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, at least one of the first surface and second surface of each casing being configured to abut onto the at least one guide;
wherein an electrical connection between the first contact elements and the first conductive portion is in a pressing contact with at least one of the first surface and the second surface of the casing, and an electrical connection between the second contact elements and the second conductive portion is in a pressing contact with at least one of the first surface and the second surface of the casing.
