Keysight is active in next-generation USB4 specifications implemented by the USB Implementers Forum (USB-IF). A wide range of products, including smartphones, laptops, desktop computers, tablets and digital cameras, rely on next-generation high-speed digital standards. USB4, a plug and play interface for inter-digital communication, is based on the Thunderbolt protocol specification and offers significant advantages in bandwidth, power and data delivery.
"Billions of devices worldwide rely on Synopsys DesignWare USB IP for connectivity, demonstrating our commitment to providing designers with high-quality IP for the most advanced protocol standards," says John Koeter, senior vice president of marketing and strategy for IP at Synopsys. "As the industry's only provider of a complete USB4 IP solution, Synopsys utilizes Keysight's comprehensive USB4 test and debug solution to help ensure that our IP adheres to the USB-IF specifications, enabling designers to deliver compliant, interoperable products to the market faster and with significantly less risk."
To enable manufacturers and brands to design debug and test, Keysight offers USB4 solutions, including test software and hardware interfaces to debug and decode signals and protocols. The Keysight D9040USBC USB4 Transmitter Test (Tx) Software is designed to rapidly test, debug and characterize complex USB4 designs, while the N5991U40A USB4 Receiver Compliance Test Software enables automation of complex stress signal calibration and receiver test procedures to ensure consistency and repeatability.
On the hardware front, Keysight offers the N7019A USB Type-C Active Link Fixture, which provides access to all Type-C signals in a live link to debug or decode acquired signals, complemented with the D9010USBP USB4 Protocol Trigger and Decode device, which can be used in conjunction with the Keysight's N7019A USB Type-C Active Link Fixture to add configurable protocol-level searches and software-based triggering to debug and decode USB4 low-speed and high-speed traffic.
"To enable the end-to-end communications ecosystem, we're proud to deliver test and measurement solutions that accelerate the development of designs like USB4," says Joachim Peerlings, vice president and general manager of Keysight's network and data center solutions group.
In accordance with the USB standard and to ensure the interoperability of USB4 devices, Keysight also offers a comprehensive portfolio of high-speed digital instrumentation including its UXR real-time oscilloscope, which provides accuracy in waveform representation across a wide frequency range, a range of Vector Network Analyzers, which use a generated signal to analyze a network or device to deliver the accuracy needed to perform both linear and nonlinear device characterization, and highly integrated Bit Error Ratio Testers (BERTs), which identify errors introduced into the system when data is received, a critical capability in physical layer characterization, validation and compliance testing.
