23:00 Solutions Summary
USB4 was released in 2019 and based on the Thunderbolt 3 protocol. USB4 adds significant complexity by doubling the data rate of USB 3.2 x2. It is expected that USB4 will be adopted in many devices. These faster signals require ultra-low noise test instruments. We will review the latest information about the USB4 test specification, challenges with implementing USB4, and Keysight test solutions.
