Testing the higher, dynamically variable power provided by the USB Type-C power delivery (PD) system requires extensive verification and testing to achieve compliance with USB Type-C standards. End-to-end USB Type-C connections between devices are made through configuration channel (CC) lines. Cable orientation — a critical factor for Type-C connectors — is also determined through the CC line. During compliance testing, important design parameters for PD that must be measured include: voltage level, device charging, cable functionality, and determination of provider versus consumer device status.
When a Type-C consumer device requests a specific power profile, verification that the connected provider sourced the right voltage, current, or wattage profile is needed. The CC lines CC1 / CC2 are monitored with a 300 kHz signal and measured for proper protocol, generated voltage, and current. The resulting eye diagram is analyzed with an oscilloscope. Verifying the PD circuit layout requires performing power integrity measurements of key parameters like supply drift, periodic and random disturbances (PARD), programmable power rail response, and high-frequency transient and noise.
