Keysight M9156C is a dual Transfer PXI hybrid switch module, which integrates two Keysight L7222C coaxial transfer switches. It is a 2 slot wide size module. M9156C operates from DC to 26.5 GHz, providing a low-cost operation switching solution for measurement and automation of Automatic Test Equipment (ATE) systems without compromise in the RF performance. It is being used in applications such as ATE, RF communications measurement and RF parametric measurements where a rugged switching module is needed for signal routing. Keysight M9156C transfer switches can be used in many different applications to increase system flexibility and simplify system design. For example, switch between two inputs and two outputs, or bypass an active device. The M9156C provides an exceptional 0.03 dB insertion loss repeatability throughout 2 million life cycle, unmatched isolation required to maintain signal integrity, with a low SWR that minimizes measurement uncertainty.
