The Agilent/Keysight 87406B is a high-performance coaxial matrix switch for automated RF signal routing in demanding test environments. Operating from DC to 20 GHz, it delivers exceptional isolation (>100 dB at 20 GHz) and repeatable insertion loss performance across millions of switching cycles. The device supports both make-before-break and break-before-make switching modes, with configurable blocking matrix architectures (3×3, 2×4, 1×5) to match specific test requirements.
