Rapid-Deployment PXI based Solution to Validate/Measure the following aspects of the USB-Power Delivery v3 or v2 specification:
- 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, Power Supply, VDM tests
- APIs Available for callability from Test Sequencers.
- Different Levels of Abstraction.
- GUI, Test, Driver, Message and Packet Formation Layers.
- Does not include USB3 Data Lines Protocol Validation. But PXI platform is scalable for this kind of enhancement.
- Both R&D and Production Test Features available. Tested well on USBPD ICs and on PD Chargers.
