The S46 and S46T microwave switch systems are designed to simplify the automatic switching required for testing various radio frequency and telecommunications products and equipment. The S46 can control 32 relay contacts within a 2U high (3.5 inches) full-rack enclosure. If your application requires termination configuration, choose the 46T system. It is built on the design technology of the non-termination system 46. The 46T system can accommodate up to eight terminated SPDT coaxial microwave relays and four terminated multi-pole coaxial microwave relays.
