The Keysight M9146A is a PXIe RF multiplexer module that routes high-frequency signals within automated test equipment systems. Built as a dual 1×4 switch configuration, it delivers bi-directional RF switching up to 3 GHz with exceptional signal integrity through low insertion loss and controlled VSWR. Unused channels terminate to 50 Ω loads, preserving measurement accuracy across dynamic test scenarios.

– Key Features
The M9146A maintains outstanding dynamic range for RF signal routing applications. Each path is engineered to deliver consistent performance without signal degradation. The dual 1×4 architecture enables flexible channel management in complex test setups, while integrated 50 Ω termination on inactive channels eliminates crosstalk and reflection.
– Typical Applications
This module addresses RF signal routing in multi-channel ATE systems, including production test environments requiring repeatable switching performance and measurement equipment interconnect.
– Compatibility & Integration
The M9146A occupies a single PXI module slot and operates in hybrid PXIe, PXI-1, or standard cPCI J1 connectors. Full software support includes LabVIEW, Visual Studio environments (C, C++, C#, Visual Basic), and MATLAB through AgMSwitch and LabVIEW G drivers (version 1.1.x or later). Integration requires Keysight IO Libraries Suite 16.0 or later, plus IVI programming support and Soft Front Panel control.
Product Status: Discontinued with continued support available.
Environmental testing per IEC 60068-2 (MIL-PRF-28800F class 3 equivalent) confirms performance across temperature, humidity, shock, vibration, altitude, and power line stresses. EMC: Class A for professional electromagnetic environments.
