Copper Mountain Technologies announced the launch of its new SN0904 4-port Vector Network Analyzer (VNA), designed to simplify the characterization and validation of multi-port RF components and systems by providing comprehensive 4-port S-parameter measurements in a compact, high-performance instrument. 

Designed for demanding RF and microwave applications, the new 4-port VNA delivers full matrix characterization, providing engineers with deeper insight into complex multi-port devices and systems. Its architecture is optimized for precision, efficiency, and scalability in modern RF test environments. 

The new SN0904 4-port Vector Network Analyzer (VNA) enables complete 4-port S-parameter characterization without the need to reconnect the device under test or perform multiple two-port measurements. This streamlined approach improves measurement efficiency, enhances repeatability, and simplifies automated test workflows, making the SN0904 well suited for RF component manufacturing and engineering applications across telecommunications, automotive, IoT, aerospace, medical devices, defense, and quantum computing research. Common applications include: 

• Differential and high-speed signal integrity measurements  
• Phased array and beamforming systems  

• RF switches and multi-port device characterization  

• MIMO and wireless infrastructure testing  

The maximum software capabilities come to standard and are available without a paid license for all customers. They include linear and logarithmic sweeps, power sweeps, time domain conversion with gating. SCPI Automation is supported through LabVIEW,C+++, VBA, Python, MATLAB, .NET, and other programming environments, and a Manufacturing Test Plug-in is available as an add-on to support incorporating VNA software into existing automated manufacturing and QA processes.
