Copper Mountain Technologies’ VNAs are used for various test and measurement applications. A fundamental requirement of most test systems is to have a good RF coaxial cable. RF coaxial cables are transmission lines which help transfer energy from one end to the other. So, it is critical to have the best performing cable which transfers the most energy possible. Copper Mountain Technologies also manufacture Automatic Calibration Modules (ACMs), which are primarily used to obtain highly accurate automated calibrations. The purpose of this seminar is to focus on how to test a cable accurately using an ACM.
