A novel measurement fixture for characterizing USB 3.0 radio frequency interference

USB 3.0 running at 5 Gbps can radiate and interfere with the wireless communication technologies integrated in mobile computer designs. The interference degrades the wireless performance such as data throughput and results in bad user experience. It is important to define compliance test methods to ensure good designs in both system and component levels. In this paper, a new and simple test fixture and the measurement methods for USB 3.0 radio frequency interference compliance testing are proposed.
