The Agilent/Keysight 87050A is a multiport test set that characterizes multi-port devices in conjunction with a two-port 50 Ω network analyzer. It enables comprehensive testing of multiple signal paths with a single DUT connection, dramatically reducing tune and test time while minimizing operator fatigue and connector wear.
Technical Specifications
• Impedance: 50 Ohms (75 Ω versions available as 87075 series)
• Switching Technology: Electromechanical (“A” models) or solid-state (“B” models); mechanical switches provide lowest loss and best isolation
• Port Configurations: Fully customizable from 6 to 24 ports with full crossbar measurement capability; specific options include 6, 8, 10, 16, 24, and 22-port configurations
• Internal Termination: All unused test ports terminated internally to minimize unwanted reflections
• Power Rating: Up to +30 dBm at test ports 1 & 2 (Option H47 for 8753C/D compatibility)
– Key Features
• Single-connection testing eliminates repeated DUT connections and reduces fixture stress
• Full crossbar switching architecture enables arbitrary port-to-port measurements
• Multiple switching technologies optimize for loss, isolation, or cost requirements
• Internal port termination minimizes reflections from unused paths
• Flexible configurations support 6 to 24 port devices in standard and custom layouts
– Typical Applications
• Duplexers and directional couplers
• Circulators and transmitter combiners
• Receiver multicouplers and distribution amplifiers
• Cable-television multitaps and splitters
• Broadband and wireless communication component characterization
– Compatibility & Integration
Designed for integration with 50 Ω network analyzers including Agilent 8719D/ES, 8720D/ES, and 8722D/ES. Option H47 specifically supports the 8753C/D analyzer. The 87050A accommodates existing test infrastructures while enabling parallel multi-port measurements that would otherwise require multiple setups or manual reconnections.
