The Keysight M9165C is a PXIe solid-state switch matrix module engineered for RF and microwave signal routing in automated test systems. Built on a 2×8 full cross-bar architecture, it delivers fast switching speeds and ultra-long cycle life while maintaining exceptional isolation to suppress crosstalk in dense ATE environments. The module operates across 300 kHz to 18 GHz with inherent temperature stability, making it ideal for multiport vector network analyzer implementations, large-scale multi-DUT measurements, and 5G massive MIMO antenna characterization. Its flexible design supports construction of custom switch configurations, providing a cost-effective approach to complex signal routing requirements.
