On May 21st, GRL and Anritsu jointly held the USB4 & PCIe 5.0 online seminar, to take you through all the technical details at home. The quota is limited, please register as soon as possible.

"USB4 is a new generation of Thunderbolt protocol led by Apple and Intel. It is backward compatible with the USB protocol. The USB4 transmission rate is increased to 40 Gbps, and the bandwidth can be dynamically shared. When a USB Type-C cable is used, it is compatible with Thunderbolt 4 and Display Port 2.0 series products on the market. It is a more convenient media for consumers. But for product developers, USB4 is a relatively big challenge. In addition to the differences in the architectural between product design and previous USB3 products, together with the attenuation of high-frequency signals on PCBs and connectors, they must pay more attention to high-frequency impedance matching. And they should ensure the quality of transmitted signals during the development stage. The requirements for copper wire transmission will become more stringent after the rate increases. With questions about these test challenges, let's discuss together.
