Abstract
Disclosed is a test and measurement switch matrix. The test and measurement switch matrix includes a solid state switch to couple a test signal from a Device Under Test (DUT) to a test system. The solid state switch has a dual tee guard arrangement providing low leakage when off. The solid state switch also includes an optically coupled drive, which further improves isolation and reduces undesirable charge injection when changing switch states.
