Fully-Automated Compliance Test Process

GRL-USB-PD software automates USB-PD Compliance Testing using GRL's Automation Framework. Compliance testing is streamlined by importing device capabilities from a user-created 'Vendor File'. Device Capabilities are then validated against the device's USB-PD Vendor Defined Message (VDM). The test plan is automatically created and executed, based on device capabilities. After testing is complete, the report is created in multiple file formats for further data analysis. Reports can be shared in industry or engineering group databases.

USB-PD ‘eMarker’ Cable Testing

The USB Type-C and USB-PD Specifications require all Fully Featured Cables and Adapters to have an eMarker Chip. Cable eMarker Compliance testing must be done at the component level and for end products. To perform Cable eMarker testing, simply plug one end of the Cable into Port A on the GRL-USB-PD-C1 Controller, and run the tests in the GRLUSB-PD software. The IR drop of a Cable can also be tested by applying a load current and measuring the Vbus drop between Port A and Port B.
