Keysight-Infiniium 90000X26 November 2014 – Keysight Technologies 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 authorized test centers 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 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.

“Keysight actively supports the USB-IF and USB implementers by providing measurement solutions early and by consistently participating in the compliance workshops,” said Jeff Ravencraft, USB-IF president and COO. “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.”

Benefits of the Keysight USB 3.1 test solution for transmitter and receiver test include:

  • Comprehensive and accurate transmitter testing.
  • Investment protection by providing 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 been used for USB 3.0 testing.
