1. An interposer for a test system, the interposer comprising:
coaxial cables, each of the coaxial cables being configured to transport a first current originating from a current source;
printed circuit boards (PCBs), each of the PCBs being connected to a set of the coaxial cables in order to receive the first current from each coaxial cable in the set and to transport a second current; and
a spring leaf assembly comprising spring leaves, each of the spring leaves being connected to a PCB in order to transport a third current obtained from the PCB to a device interface board (DIB) that connects to devices under test (DUTs) to be tested by the test system, each of the spring leaves having one of a plurality of polarities defined by the third current;
wherein the coaxial cables on each PCB are arranged in parallel, the PCBs are arranged in parallel, and the spring leaves on each PCB are arranged in parallel; and
wherein on each PCB, a set of the spring leaves is arranged such that adjacent spring leaves have different polarities.
