The Keysight P9165B is a 2×8 full crossbar solid-state switch matrix that routes RF and microwave signals across automated test setups from 300 kHz to 9 GHz. USB control and integrated 50 Ω termination on unused outputs simplify deployment in multi-DUT and multiport measurement systems, including 5G massive MIMO antenna testing.
