Granite River Labs (GRL), a global leader in engineering services and test solutions for connectivity, today announced major enhancements of their second generation USB Power Delivery (USB PD) and USB Type-C® comprehensive test solutionGRL-USB-PD-C2 (GRL-C2). With these new enhancements, GRL-C2 is the only USB-IF approved USB PD solution for all three of the Communications Engine MOI, Deterministic MOI, and USB PD Specification Revision 3.0 USB-IF compliance program.

GRL-C2 automates all required USB PD compliance tests for power providers (chargers), consumers, dual-role ports, and cable and adapter E-Markers. GRL-C2 also incorporates analyzer capability to sniff PD traffic.

“We are very pleased that our latest generation USB PD test solution has been officially approved for the major USB PD 3.0 and 2.0 compliance test items,” said Johnson Tan, GRL Co-Founder and CEO. “GRL-C2 successfully underwent extensive correlation and validation with the USB-IF to achieve this status.  GRL-C2 customers can rest assured that they made a sound investment in the most proven and full-featured USB PD solution available.”
