Agilent/Keysight M9161D

The Keysight M9161D is a PXI Solid State Dual SP4T Switch Module that routes RF and microwave signals across a 50 MHz to 20 GHz frequency range in automated test environments. This single-slot module integrates into PXI, CompactPCI, and Hybrid chassis platforms, delivering 60 µs switching speed, 100 dB isolation at 6 GHz, and ultra-long cycle life to minimize total cost of test and crosstalk in dense ATE systems.
