Driving down the cost of test is a key challenge in high-volume component manufacturing. The trend towards adding more ports on components such as antennas, cables, and frontend modules (FEMs) increases the need for accurate and fast multiport network analysis. Minimizing operator intervention and reducing connection and calibration times is essential to increase measurement throughput. Optimizing your vector network analyzer (VNA) configuration is critical to minimizing the cost of test in manufacturing. That’s when the multiport and multisite testing concepts come in, but there are challenges.
