CASE ANALYSIS
Scenario
A test engineer needs to repeatedly connect and disconnect a USB-C dock under test while measuring VBUS power and verifying PD negotiation, automating cycles via host software.
Key decisions
- Use a programmable mux switch to break both power and SuperSpeed data
- Separate PD negotiation path from the switched power/data path
- Monitor VBUS power at the dock to capture inrush and disconnect events
When to reuse this
Reusable for any USB-C dock or hub qualification rig where automated connect/disconnect cycling and power monitoring are required.
