The Keysight M9155C is a dual SPDT PXI hybrid switch module, which integrates two Keysight 8765C coaxial switches. It is a 1 slot wide size module.

The M9155C operates from DC to 26.5 GHz, providing a low-cost switching solution for measurement and automation of Automatic Test Equipment (ATE) systems without compromising RF performance. It is used in applications such as ATE, RF communication and RF parametric measurements where a rugged switching module is needed for signal routing. Typical switching applications for SPDT coaxial switches include signal routing of a single input to dual instruments.

The M9155C provides an exceptional 0.03 dB insertion loss repeatability throughout a 5 million life cycle, unmatched isolation required to maintain signal integrity, and a low SWR that minimizes measurement uncertainty.
