In this video, Subbaiah Pemmaiah, Technical Director at Copper Mountain Technologies, showcases the advantages of 1-Port USB VNAs, including powerful software capabilities and real-world RF applications. The 1-Port VNA Series (reflectometers and cable/antenna analyzers) delivers lab-grade measurement accuracy in a compact, handheld form factor.

These VNAs feature direct connection to the DUT (no test cables required), Time Domain Analysis, Distance to Fault (DTF) measurements, and multi-platform software support. With license-free CMT software, teams can easily share and scale testing workflows. Ideal for field and lab use, these solutions provide accurate, efficient RF measurements for cables, antennas, and more.

For 15 years, Copper Mountain Technologies has provided innovative & high-performance VNA solutions developed for production lines, R&D, and lab environments - empowering engineers worldwide with accurate, scalable, and cost-effective RF testing. Headquartered in Indianapolis, Indiana (USA), we maintain manufacturing, research & development, applications engineering and service operations in both the United States and Paphos, Cyprus (EU), with additional regional offices in Singapore, London, and Miami. We offer a broad range of USB vector network analyzers, calibration kits, and accessories for 50 Ohm and 75 Ohm impedances to 330 GHz. Our VNAs use software for Windows®, Linux® macOS® operating systems on an external computer, PC, or tablet. Every CMT VNA includes robust application and automation support, backed by years of RF engineering expertise dedicated to customer success.

See how Copper Mountain Technologies'' embedded S-parameter modules bring VNA measurement capabilities into OEM products and specialized test systems. Designed for integration into application-specific equipment, these modules provide accurate S-parameter measurements in a compact format. CMT works with OEMs to adapt the measurement solution to their hardware, software, and system requirements. CMT VNA software is natively supported with use on Windows, MacOS, Debian Linux, and ARM-based operating systems, such as Raspberry Pi, for maximum adaptability and an ultra-minimized footprint.

SN0904 4-port Vector Network Analyzer (VNA) is 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. Developed 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.

This video demonstrates how to perform time domain measurements using a vector network analyzer (VNA), specifically illustrating the process with a Copper Mountain Technologies'' 2-Port VNA. The presenter, Brian Walker, walks through the setup required for time domain reflectometry (TDR), explaining the significance of using a lowpass time domain measurement with a step function, as well as what bandpass and impulse functions can be used for.
