Responding to an increasing market demand for fast development of USB 3.1 Gen 2 designs and designs using other high-speed signal standards that support the Type-C connector, Keysight Technologies introduced its N7015A high-speed test fixture, which the company says it’s the industry’s highest-signal-integrity Type-C test solution for high-speed differential bus probing.
More demands are being made on PCs, tablets and other consumer electronics, creating the need for faster data transfer and higher power delivery. With high-speed data rate support, the ability to support multiple industry-standard high-speed protocols, and a power delivery infrastructure with up to 100 watts, the Type-C connector is set to be a key feature in many upcoming products.
Keysight Technologies introduced the industry’s highest-signal-integrity Type-C test fixtures for high-speed differential bus probing. The Keysight N7015A high-speed test fixture provides best-in-class performance up to 30 GHz of bandwidth, enabling engineers to verify and debug USB 3.1 Gen 2 designs and designs using other high-speed signal standards that support the Type-C connector.
The N7015A Type-C high-speed test fixture separates out four lanes of high-speed protocol signals for signal measurement or injection and sends low-speed power and control line signals to a secondary fixture, the Keysight N7016A Type-C low-speed signal access and control fixture. The flexible fixture kit provides high-signal-integrity access to signals and enables engineers to probe the USB 3.1 device and host upstream and downstream ports.
The N7016A low-speed Type-C fixture manages power and control lines from the N7015A to support termination requirements and test configuration as well as connection to a third-party power delivery controller.
“Type-C is the future of connection technology in consumer electronics, and it has far reaching implications,” says Dave Cipriani, vice president and general manager of Keysight’s Oscilloscope and Protocol Division. “Our Type-C test fixtures are just the first piece of a larger, automated Type-C testing solution Keysight is developing to help our customers meet this revolutionary technology’s testing challenges.”
The N7015A fixture is reversible, meaning that engineers can flip the plug 180 degrees without affecting testing. It is designed so users can place two fixtures side by side or stacked one on top of the other. Whether connected side by side or stacked, the fixtures meet the minimum spacing allowed in the specification. The fixture’s durable design ensures multiple connections and disconnections without failure in an active test environment.
While the N7015A fixture has the highest signal integrity, it also comes with an S-parameter model that can be used to de-embed signal loss up to 30 GHz, giving engineers more accurate measurements of their device’s behavior. Designers can use the Type-C connector with technologies such as USB, DisplayPort, Thunderbolt and MHL. Keysight offers approved compliance test software for all of these technologies.
The N7016A Type-C low-speed signal access and control fixture is connected to the N7015A fixture through a captive Type-C cable, which conveys CC1, CC2, Vbus, SBU1, SBU2 and ground signals. It allows engineers to break out the USB 3.1 signals from downstream USB devices for system diagnosis and control. The fixture also allows for signal probing with a high-impedance passive probe for in-depth signal analysis.
The N7016A Type-C low-speed fixture requires the installation of a software controller. It comes with free controller software that can be installed on a PC or Infiniium oscilloscope. Keysight Type-C test fixtures are fully available for pre-order, with limited shipments forecasted to begin in December 2015.
