The Keysight U7104E is a single-pole-four-throw (SP4T) electromechanical switch module for RF and microwave test applications spanning DC to 50 GHz. This latching, terminated multiport switch delivers the isolation and return loss performance required in automated test systems, signal routing, and multi-device measurement scenarios. Port count expansion becomes practical without sacrificing RF integrity, enabling cost-effective scaling of test architectures while maintaining measurement repeatability and system reliability.
Technical Specifications

– Key Features
• Low insertion loss and reflection reduce measurement uncertainty in complex switching matrices
• Opto-electronic current interrupts provide circuit protection and operational feedback
• High repeatability supports demanding automated test applications
• Latching design ensures stable, predictable switching behavior
• 50-ohm port termination maintains signal integrity across unselected paths
– Typical Applications
• Multi-DUT or multiport device testing
• Signal routing and monitoring in RF/microwave test benches
• Large, multi-tiered switching systems
