Teledyne LeCroy Upgrades Voyager USB Platform to Addresses 100% of Required USB Power Delivery and USB Type-C™ Compliance Tests

Teledyne LeCroy's 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 increases the number of test specifications fully addressed by the Voyager M310P to four.

"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 Teledyne LeCroy's 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 extends the capabilities of the Voyager M310P to perform 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 as defined by the "PD Communications Engine" MOI.

In addition to the eye-diagram tests, the Voyager M310P also adds the USB Battery Charging (BC) 1.2 emulation mode required for specific USB Type-C compliance tests. The ability to source VCONN at 3V represents a new USB PD compliance check for Electronically Marked cables. The ability to source out-of-range of VBUS voltages (under 3.67V) is needed to verify that DRP devices correctly detect the un-attached state. The ability to sink VCONN current as low as 100 mW was added to verify source devices continue to provide VCONN current during suspend mode. Improved detection circuitry is required to verify devices properly enter the USB 'safe-state' on CC, SBU, and the USB 2.0 (D+/D-) lines. The analyzer mode of the Voyager M310P is also enhanced to support 4-lane DisplayPort signaling for USB Type-C devices that support Alternate Modes.
