The Keysight U3042AM20 is a 26.5 GHz mechanical test set that expands the port capacity of 4-port network analyzers to deliver 24-port full crossbar measurement capability in a single connection. This 20-port multiplexing module integrates with PNA, PNA-L, and PNA-X series instruments, enabling simultaneous characterization of multiport devices across the entire microwave frequency spectrum.
Technical Specifications
Frequency Range
• Maximum Frequency: 26.5 GHz

• Combined System Ports: 24 (when connected to a 4-port network analyzer)
• Measurement Capability: Full crossbar configuration
– Key Features
• Mechanical switching architecture for deterministic port sequencing
• Single-connection measurement approach eliminates reconfiguration overhead
• Direct integration with established Keysight network analyzer platforms
• Maintains calibration and measurement integrity across all 24 ports
– Typical Applications
• Multiport RF and microwave device characterization
• High-frequency passive component testing (switches, filters, couplers)
• Antenna and connector validation across multiple ports
• Automated production test of port-intensive assemblies
• S-parameter acquisition across large port matrices
– Compatibility & Integration
The U3042AM20 connects directly to Keysight PNA, PNA-L, and PNA-X series network analyzers equipped with four measurement ports. No external controllers or proprietary interfaces are required. System configuration requires a single network analyzer connection, enabling rapid setup and deployment in both laboratory and production environments.
