Agilent/Keysight M9156C

The Keysight M9156C is a PXIe hybrid dual transfer switch module that routes RF and microwave signals in automated test equipment systems. It integrates two L7222C coaxial transfer switches in a 2-slot PXIe form factor, enabling signal routing between two inputs and two outputs across DC to 26.5 GHz. The module delivers exceptional mechanical reliability with 0.03 dB insertion loss repeatability guaranteed over 2 million cycles, extending to 5 million cycles typical operation. Isolation reaches 94 dB at 8 GHz and 60 dB at 26.5 GHz, critical for minimizing crosstalk in dense ATE environments.
