Testing solutions for USB4 - Universal Serial Bus 4
2020-08-20 | 3 min read
Overview
The USB Implementers Forum (USB-IF) announced USB4 in March 2019 and released the specification in September 2019. Based on the Thunderbolt 3 protocol, USB4 uses a Type-C connector, which enables bonding of two independent 20 Gb/s links into one logical 40 Gb/s link. USB4 supports other standards through ALT mode. The host implements USB 3.2 at 5G / 10G, USB 2.0, and DisplayPort (DP) and can tunnel USB, DP, and PCIe®. Keysight offers a suite of hardware and software tools to help you design and implement USB4.
USB4 has seen significant changes compared with USB 3.2. These are some of the testing differences in the USB4 implementation:
Figure 2 provides a comprehensive overview of hardware and software needed to complete transmitter and receiver tests for USB4 Type-C.
The USB4 Type-C solutions matrix uses the following tools:
Conclusion
Keysight offers a suite of testing solutions that will help you implement your USB4 design, including testing all supported technologies:
• protocol
• USB power delivery
• channel characterization
• sideband testing
• Thunderbolt
• DisplayPort
As described, Keysight offers instrumentation, software, and fixtures for testing and characterizing the entire USB4 Type-C ecosystem.
