The Keysight P9165B is a 2×8 USB solid state switch matrix engineered for routing RF and microwave signals across automated test equipment systems. Operating from 300 kHz to 9 GHz, this full crossbar configuration delivers switch-based multiport VNA solutions with exceptional isolation and fast switching performance. The instrument handles high-density measurement scenarios, including 5G massive MIMO antenna characterization, with minimal crosstalk and ultra-long solid state switch cycle life.
