Abstract
Embodiments of the present invention provide an improved two-cable connection system for connecting electrical test instrumentation to a device under test (DUT). In one embodiment, a single pair of equal-length triaxial cables each has a desired characteristic impedance. Each cable has a center connecter, intermediate conductor, and outer conductor. The proximal end of each cable is connected to the test instrumentation, and the distal ends are located at the DUT. At the distal end, the center conductors are connected to the DUT, the intermediate conductors are allowed to float, and the outer conductors are connected to each other. The proximal end of each cable is connected to the device using an appropriate connection for the test that will be performed. This allows the test instrumentation to perform different types of tests without changing connections to the DUT.
