Analyser upgraded for USB-C power delivery compliance testing

July 20, 2017 // By Nick Flaherty
Teledyne LeCroy has upgraded its USB analyser to provide 100% coverage of the required USB Power Delivery (PD) and USB Type-C functional compliance tests.

The Voyager M310P is a full-featured USB 3.1 protocol analyser/exerciser system that now supports eye-diagram capture and bit-error-rate test functionality to provide one-stop verification for PD and USB Type-C compliance.

The Voyager platform has been widely used at the USB-Implementers Forum (USB-IF) Compliance and Interoperability workshops for the last 8 years where it is an approved verification system for SuperSpeed USB 3.1 Link Layer and Hub compliance. The additional coverage of USB Type-C and USB PD compliance means four USB test specifications are fully addressed by the analyser.

"All USB Power Delivery enabled devices are required to use the USB Type-C connector which means they must pass tests verifying compliance with both the PD and the USB Type-C specifications," said Jeff Ravencraft, USB-IF President and COO. "Compliance Verification systems like the Voyager M310P play an important role in the USB-IF's efforts to ensure reliable and compatible USB end products."

"It's easy to see the advantages of the Voyager M310P, the only single-box solution designed to address every USB PD and USB-C test point, including several new assertions added in the most recent specification updates," said Joe Mendolia, vice-president of Marketing at Teledyne LeCroy. "The Voyager M310P now fully supports both USB PD 2.0 and USB PD 3.0 as well as Link Layer (Ch. 6 & 7) and Hub (Ch.10) compliance which makes it highly cost-effective for validation teams working on the latest USB technologies."

The Voyager M310P relies on built-in traffic emulation modes to perform the USB Power Delivery Compliance testing. The addition of eye-diagram capture and bit-error-rate test functionality allows signal integrity testing on the USB PD Communications Channel (CC).  To complete the noise immunity tests, the Voyager M310P incorporates an arbitrary waveform generator (AWG) designed to generate an aggressor signal that closely matches the frequency spectrum of the USB 2.0 signal.  These enhancements allow the Voyager M310P to fully support the USB-IF's USB PD Compliance Plan.
