Double Ended Sockets Overview

Double-ended sockets are comprised of a standard socket with a special interface probe permanently attached to the tail of the socket. Double-ended sockets allow construction of fixtures with far shorter signal path lengths than conventional wire-wrapped designs. The shorter path length allows better control of the signal from the tester circuits to the Unit Under Test (UUT). Note: Top test probe is not included with double ended sockets and should be ordered separately (see applicable product series)
