Keysight Technologies Updates Step-by-Step Guide for USB Type-C Connector and Cable Assembly Compliance Testing

December 17 2015, 03:00

Keysight Technologies announced the availability of a newly updated Method of Implementation (MOI) document for cable and connector assembly compliance tests defined in Rev. 1.1 of the USB Type-C specification and Rev. 1.0 of the USB Type-C Compliance Test Specification (CTS). The step-by-step document provides measurement procedures for compliance testing USB Type-C cables and connectors in the time and frequency domains, using  the ENA Network Analyzer.

The USB Type-C MOI, together with a test package such as Keysight’s state file, works with the ENA Series network analyzer’s enhanced time domain analysis option (E5071C-TDR) to provide the compliance test solution for USB Type-C cable and connector assemblies. This step-by-step guide of measurement procedures for time and frequency domains simplifies USB Type-C cable-connector compliance setup and testing. As part of Keysight’s Type-C total solution set, the ENA-TDR is ready for complete testing of the standards converging on this universal interface.
Driven by increasing demand for more bandwidth, USB continues to evolve. One such evolution is the move to Type-C connector, with its’ 24-pins and a symmetric form factor that enables users to plug it in either way. The smaller connector results in tougher requirements for the physical layer to ensure interoperability. While Keysight currently offers a MOI for these smaller connectors, it is based on version 1.0 of the USB Type-C specification and CTS draft. The newly updated MOI, however, is based on the latest versions of both specifications: USB Type-C 1.1 and CTS 1.0.
“Keysight MOIs are available for a number of different high-speed digital applications such as HDMI, Ethernet and PCI Express,” explains Akira Nukiyama, vice president and general manager, Keysight’s Component Test Division. “Our newest addition to this list, the updated USB Type-C MOI, is yet another example of how we are working to give our customers the functionality they need to address high-speed measurement challenges and meet their time-to-market goals.”

The newly updated USB Type-C MOI for use with the E5071C-TDR is available now at Additional information on the MOIs available for E5071C-TDR is available at

The E5071C ENA-TDR is a software application embedded in the ENA network analyzer that provides a one-box solution for high-speed serial interconnect analysis.
