1 Type-C Connectivity Solution - Overview10 Keysight Type-C Connectivity Solution User GuideHow the Type-C Test Fixtures Work TogetherA high level overview of how these Type-C test fixtures work together is provided below. For details,refer to the individual chapters in this guide dedicated to these fixtures.The N7015A test fixture connects to a DUT and a compatible oscilloscope to break out fourdifferential lanes of Type-C high-speed signals from the DUT to the oscilloscope. These high-speedsignals can be monitored and analyzed using the Keysight Infiniium software installed on theoscilloscope.For low-speed power and control signals access, the N7015A test fixture connects to the N7018Atest controller or the N7016A test fixture and passes the Vbus, SBU, and CC lines to the N7018A /N7016A via a USB Type-C (plug style) cable. There are probe points for Vbus, SBU, and CC lines onthe N7018A or N7016A to allow you to probe these low-speed signals at these fixtures.The USB Type-C cable that connects the N7015A to the N7018A also serves as the connectionmechanism between the N7018A and DUT with the N7015A test fixture in between. Using this cable,the N7018A establishes a Type-C connection and a standard 5V PD contract with DUT andadvertises the user-selected mode of operation (ALT Mode) and power delivery role to the DUT.Once the connection is established, the N7018A can negotiate a new PD contract with the DUT onthe selected CC line using the USB PD protocol. This PD contract is as per the settings that youconfigured for the N7018A.When USB PD negotiations are complete, the N7018A enables the appropriate power path andnegotiates and enters the user-selected ALT Mode. It enables, discovers, configures, andenters/exits the selected Alt Mode with the DUT via a USB PD protocol handshake.All these configurations and control of the N7018A test controller including connection, power role,ALT modes, and power delivery contract settings are done using the N7018A software (see page 72).To provide power to the N7016A / N7018A test fixtures and control and configure these fixturesusing their software, you connect these to an oscilloscope or a host computer via the supplied USBcable. An external power supply is needed if the N7018A / N7016A is acting as a power deliveryprovider to DUT.If you are using the N7016A, a power delivery controller is also needed. If you are using the N7018A,then you do not need a power delivery controller as the N7018A acts as a power delivery controlleras well.Besides signals monitoring and analysis, characterization, and debugging, these test fixtures alsoallow you to run various compliance tests. The N7018A / N7016A test fixtures are integrated with anumber of Keysight compliance applications software to allow you to do automated compliancetesting when using these test fixtures.
