Teledyne LeCroy’s legendary Voyager analyzer platform provides the industry’s most accurate and reliable capture of USB 3.2, USB4 and Thunderbolt™ 3 protocol for fast debug, analysis and problem solving. Leveraging Teledyne LeCroy's cutting-edge T.A.P.4™ probe technology and industry-leading analysis software, the newest Voyager is the ultimate, all-in-one test solution for USB.
The Voyager M4x features the industry’s highest fidelity probe design and provides unmatched reliability when testing devices at the full USB4 Gen3x2 (40Gb/s aggregate) speed. Designed to sit inline between host and hub, the M4x will non-intrusively record all USB Type-C signaling including USB 3.2 / USB4 / TBT3 data, side-band and CC (PD) messages. Hot plug any combination of USB4 host and hub and the Voyager system will record the speed negotiation handshake and lock at the specified rate. Full support for capturing USB 3.2 bonded traffic (20 Gb/s aggregate) over Type-C also fills a critical need for developers targeting Superspeed USB 3.2 applications.
The Voyager utilizes the legendary CATC Trace - the industry's de facto standard display and shows all packets labeled and interleaved in a single view. Traffic from the logical USB4 and side-band channels can be individually filtered, searched or exported from the trace. The Transfer level can be expanded and collapsed to show the logical layer including all ordered sets and control packets. While in line, it will record and display all register reads and writes to provide an unambiguous picture of the router and path configuration space. The HopID window allows precise hiding of traffic based on Hopid and Protocol Defined Function (PDF). Isolating traffic on specific paths provides a coherent picture of the full configuration sequence for each PCIe, USB or DP adapter within the network.

The front-end of the Voyager analyzer features USB4 rated connectors that support the full 40Gb/s data rate for loss-less capture of traffic from all active links simultaneously. The Voyager M4x platform includes 32GB of recording memory plus USB 3.0 and Gigabit Ethernet links for uploading recorded traffic to the host PC. The Voyager is fully compatible with both active and passive cable environments. Field upgradeable firmware ensures future support for new features or changes to the USB specification.
The Voyager provides hardware triggering to pinpoint protocol events of interest. Trigger events can be specified at the lowest levels including bus states and ordered sets (TS1/TS2, De-Skew, CL2_ACK). Updates will address header fields including hop ID. For packet types (tunneled, control, credit_sync, etc..). Triggering on CC events including Alt-mode and PD messages, VBUS and CC voltage levels are also supported.
USB4 Exerciser Option
The exerciser adds a flexible traffic generation capability for USB4 and Thunderbolt™ 3 to the Voyager M4x platform. It allows users to transmit custom packets over standard USB Type-C cables with low-level control of headers, payloads, timing, and link states. Seamlessly integrated with the protocol analyzer, the M4x exerciser can emulate host or device router operations while recording the real response from the DUT. Leveraging the same proven architecture developed for SuperSpeed USB, the M4x exerciser adds Gen3x2 and Gen2x2 support allowing users to perform initial power-on, functional and compliance testing for next generation USB4 chipsets.
Future Exerciser Capabilities
A comprehensive exerciser and compliance test capability for PD 3.0 and USB 3.2 will be available as optional enhancements in the future. Script-based APIs will allow users to transmit any arbitrary sequence of USB and PD messages for functional and conformance testing.
The Teledyne LeCroy Voyager can detect and flag real USB4, USB 3.2 and PD protocol errors. At the lower layers, training sequences, SCR content and CRC values are automatically checked for errors. Configuration Packet Timing is verified along with many USB 3.2 / USB4 logical layer timing requirements.
Find the Issues Fast
The Voyager software provides many mechanisms to measure and report on USB & PD protocol. With the Traffic Summary display, users can evaluate statistical reports at a glance or navigate to individual events. Users may select packets or link commands then jump to each occurrence with a single keystroke. Higher-level events are also tracked and reported at the logical transport layer.
USB4 Tunneled Protocol Decoding
For Tunneled PCI Express, Data Link Layer Packets (DLLP) and Transaction layer events are decoded allowing users to see critical fields like address and Requester ID. When capturing tunneled DisplayPort, AUX messages are separated from the video main data stream for easier interpretation. All fields for tunneled USB packets are fully decoded. Higher layer USB events including device class transactions will be decoded in a follow-on release.
Measure and verify VBUS and CC voltages with PowerTracker
The Voyager M4x Power Tracker option monitors and displays vBus power and current graphically in a time-line format. The voltages are synchronized to trace events allowing users to verify power state transitions at the protocol and electrical layers. Separate power graphs are provided for CC and VCONN making it easy to debug logical Type-C state transitions.
The Voyager system features countless innovations in data analysis to help reduce time-to-market for USB systems and devices. Combined with future enhancements bringing exerciser and compliance testing, the Voyager platform is well suited for low-level USB4 silicon validation as well as system and software level verification.
