The Model 7153-Factory Refurbished is designed to switch low level, high voltage, and high impedance signals for applications such as parametric tests on semiconductor devices. The 7153-Factory Refurbished allows signal levels up to 1300V while maintaining offset current of <1pA (typically 10fA) and path isolation >1013Ω. Each crosspoint is a 2-pole relay to switch both signal and guard. Interconnect between the matrix and instruments such as the Model 237 SMU is done with the 7153-Factory Refurbished-TRX cable. This cable has an M-series connector for the matrix and five 3-slot male triax connectors at the opposite end. The cable will mate with the row or column connectors of the Model 7153-Factory Refurbished.
