Teledyne LeCroy Voyager M310e USB Analyzer

Teledyne LeCroy’s Voyager M310e performs USB Power Delivery 3.1 specification testing

  • Teledyne LeCroy’s Voyager M310e test platform integrates a SuperSpeed USB 10Gbps protocol analyzer and exerciser in a single instrument.
  • It now supports the new USB Power Delivery 3.1 specification as well as the full range of features required for USB compliance testing.

USB Power Delivery technology allows laptops, mobile phones and peripheral devices to be powered and charged through USB-C ports. The newly released USB PD 3.1 specification more than doubles the power range available, stretching it from 100W to 240W, enabling USB Type-C cables to power high-performance laptops and to charge devices faster.

“USB Power Delivery 3.1 higher wattage capabilities will continue to strengthen adoption by consumer electronic devices and support the industry’s goal of reducing electronic waste by increasing re-usability of power adapters and chargers,” said Jeff Ravencraft, USB Implementers Forum (USB-IF) President and COO.

“The introduction of the Voyager M310e means that USB PD developers and test labs can eliminate redundant test tools and partial implementations from their USB PD test bench and instead rely on the Teledyne LeCroy test platform to provide the widest coverage of official USB-IF compliance specifications”, said Joe Mendolia, vice-president of Marketing at Teledyne LeCroy.

The Voyager M310e replaces the Voyager M310P analyzer and exerciser for validating USB designs with the USB-IF compliance test specifications. In addition to SuperSpeed USB 10Gbps Link Layer, Hub, and USB Type-C support, the Voyager M310e fully supports USB PD 3.1 functionality. The exerciser port of the Voyager M310e is also enhanced to capture side band use (SBU) and auxiliary (AUX) messages for USB Type-C devices that support USB4 or DisplayPort Alternate modes.

Using Teledyne LeCroy’s industry-standard USB Protocol Suite software, the M310e provides thorough protocol analysis and traffic generation for SuperSpeed USB 10Gbps links and serves multiple roles during USB system validation. The compliance test option connects to devices over standard USB Type-C cables and utilizes emulation scripts to mimic link partner behaviors. It captures message exchanges and automatically verifies the correct protocol and power behaviors. The Voyager M310e also features improved connectors and other components designed to provide better low frequency periodic signaling (LFPS) detection as well as more robust control for voltage and current.
