S46 and S46T Microwave Switch Systems are designed to simplify the automated switching needed to test a wide range of RF and telecommunication products and devices. The S46 can control 32 relay contacts in a package as small as a 2U high (3.5 in) full-rack enclosure. Choose the System 46T if your application requires a terminated configuration. It builds on the design technology of the unterminated System 46. The System 46T accommodates up to eight terminated SPDT coaxial microwave relays and four terminated multi-pole coaxial microwave relays.
