Next steps for USB; transmitter testing configuration for USB 3.1

October 16, 2014 // By Graham Prophet
Keysight Technologies has introduced transmitter (TX) test support for the USB 3.1 specification with the U7243B USB 3.1 transmitter performance validation and compliance test software.

The test software allows authorised test centres to certify SuperSpeed USB and SuperSpeed USB 10-Gbps devices and gives in-house test and performance validation engineers the tools to ensure their devices comply with the USB 3.1 specification. The Keysight USB 3.1 solution provides accurate test results to reduce development costs and simplify measurement processes for test engineers in the consumer electronics, cable manufacturing and semiconductor industries.

The test software operates on Keysight's 90000 X-, Q- and Z-Series Infiniium real-time oscilloscopes with bandwidths of 16 GHz and higher. Access to the test signals through a USB test fixture is required.

Jeff Ravencraft, USB-IF president and COO, comments, “As we move towards higher speeds, the measurement and physical layer compliance solutions that companies like Keysight provide are essential for the USB-IF testing and certification program to ensure a seamless computing experience.”

The Keysight USB 3.1 test solution for transmitter and receiver test gives:

- Comprehensive and accurate transmitter testing.

- Signal generation and analysis capability for a variety of bus standards, including USB, PCI Express, SATA and DisplayPort.

- Configurability and flexibility for debugging devices.

Engineers can use the solution with the USB Implementers Forum (USB-IF) approved fixtures or the Keysight U7242A fixture, which has also been used for USB 3.0 testing.
