A vector network analyzer (VNA) is a key instrument in the evaluation of radiofrequency (RF) devices and coaxial cables, as it analyzes how high-frequency signals are transmitted and reflected through a device under test (DUT). <\/p>\n\n\n\n

Copper Mountain VNAs are known for their precision and portability, with models covering a wide frequency range from 9 kHz to 330 GHz. They are ideal for applications in telecommunications, research, and development.<\/p>\n\n\n\n

A USB VNA<\/strong>, such as those from Copper Mountain<\/a>, generates RF signals that are applied to the DUT to measure transmitted and reflected signals, separating signals traveling in opposite directions on a transmission line. The bridges in the VNA split these signals between two ports, and its receivers analyze the incoming and outgoing waves. By normalizing magnitudes and phases, the VNA can predict the DUT's behavior under various impedance conditions, which is essential for accurate and reliable evaluation.<\/p>\n\n\n\n
