The document outlines a proprietary Type-C USB-PD testing platform designed for rapid deployment and validation of power delivery over CC lines. It supports USB-PD specifications, including functional validation, protocol testing, and user-defined tests, and features a modular architecture with APIs for integration. The platform is tested on USB-PD integrated circuits and chargers, offering R&D and production test capabilities.

TYPE-C USB-PD Port Functional Test and
Parametric Measurement Platform
• Instantiable, Rapid-Deployment PXI Based Solution to
Validate/Measure
• BMC Baseband Modem TX and RX Eye Diagram, Cable
Idle Detection and Noise Rejection capabilities for the
CC Lines for any Type-C Downward Facing Port.
• Power Contract Negotiation over CC Line- Functional
Validation
• Protocol Layer, Policy Engine and Power Supply Tests
• Supports Rev-2 and Rev-3 of the USB-pD Spec.
• APIs Available for callability from Test Sequencers
• Does not include USB3 Data Lines Protocol Validation
(Includes Power Delivery Lines only). But PXI platform is
scalable for this kind of enhancement.
• Both R&D and Production Test Features available.
• Solution tested on USBPD ICs and on PD Chargers
