U4612A USB 3.0 Jammer

Overview

Developers and integrators of SuperSpeed USB technology verifying design robustness and error recovery of their systems are facing a challenging task. Getting to the root of a problem can be especially challenging when it is difficult to duplicate test cases and customer issues. Troubleshooting is further complicated by the wide range of devices encountered in an USB environment, ranging from HD video to human interface devices such as keyboards and mice. The Keysight Technologies, Inc. U4612A USB 3.0 Jammer gives developers the ability to insert a variety of errors into live data, testing the system’s real-time error handling system recovery as well as the duplication of errors seen in the field.

The U4612A USB 3.0 Jammer provides the ability to create random and defined line errors such as CRC or 8b10b encoding errors, and modify or replace Link Commands, protocol packets, packet data, and ordered sets so that the system under test can be quickly stressed to its limits. Used in conjunction with the Keysight U4611A/B USB 3.0 Protocol Analyzer, the system’s response to the issues created by the jammer can easily be isolated and identified. The GUI provided for the U4612A is integrated with the Analyzer’s USB SuperSpeed Analysis software provid­ing an integrated system seamlessly linking error generation with analysis of the system’s response.

The Keysight U4612A USB Jammer front panel’s activity and status LED indicators give the user confidence the jammer and DUT is set up cor­rectly and functioning as desired. Additional test equipment such as Keysight logic analyzers and mixed signal oscilloscopes expand the view of the total system under test by means of the U4612A trigger capabili­ties. For example, the jammer can be commanded to insert errors into the USB data at a specific point in the operation of the DUT by either the logic analyzer or oscilloscope, giving the user the ability to trace system operation across many phases of the DUT operation.
