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 3.2 / USB4 / TBT3 / TBT4 data, side-band and CC (PD) messages. Hot plug any combination of USB4 host and hub and the Voyager system will record the sideband discovery plus the speed negotiation sequence 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 provides hardware triggering to pinpoint protocol events of interest. Trigger events can be specified at the lowest levels including bus states, ordered sets, VBUS & CC voltages, PD messages, protocol errors or header fields including address or packet types. For USB4 Tunneled traffic, trigger on any data pattern within the first 5 DWORDS of a frame.
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 is available with up to 32GB of recording memory plus USB 3.0 and Gigabit Ethernet links for uploading recorded traffic to the host PC. Field upgradeable firmware ensures future support for new features or changes to the USB specification. Economical USB 3.2 configurations are available today that support bonded USB traffic (20 Gb/s aggregate) over Type-C while allowing future upgrade to USB4 analysis.
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.
All the logical link sub-states are recorded and displayed including SLOS1/SLOS2, TS1, TS2, and deskew ordered sets. Sideband registers are parsed to automatically assign protocols to HopIDs. Register Read Request / Response transactions are fully decoded. The configuration space viewer populates router, adapter and path entries dynamically to provide an easy to read (32-bit table) view of the adapter configuration process. For DP alt-mode testing, DP Aux commands are captured and decoded. More extensive decoding is available by exporting the tunneled traffic to Teledyne LeCroy PCI Express or DisplayPort analyzer applications.
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.
The Voyager software provides many mechanisms to measure and report on USB and 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 USB4 transport layer.
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.
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 can be exported to a standard USB trace with full decoding including all device class traffic.
For comprehensive tunneled decoding, the Voyager M4x allows instant export of tunneled traffic to the full featured Video Protocol Suite and PCIe Protocol Suite applications. These are the same full-featured, market-leading applications developed by Teledyne LeCroy’s video and PCIe groups and include a vast array of analysis and debug tools (available as a free software download).
The exerciser option adds a flexible traffic generation capability for USB4, Thunderbolt 3, and USB 3.2 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 system 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 & USB 3.2 chipsets.
The Voyager M4x offers broad support for USB Compliance testing including USB Type-C, PD (SPR only), USB4, USB 3.2 Link Layer, and DP Alt-Mode. Utilizing Teledyne LeCroy’s Voyager exerciser capability, the Compliance Suite is an automated application that utilizes emulation scripts to mimic USB, PD, and Type-C link behaviors. The exerciser is used to initiate and respond to USB and PD commands like a real device while analyzing the response from the DUT. It communicates directly over Type-C cabling, records and analyzes every protocol exchange to determine correct behavior. For Type-C and PD Compliance, the exerciser leverages a comprehensive library of high-level commands to emulate Type-C source, sink and DRP behaviors.
The Voyager M4x offers exclusive support for USB 3.2 10Gps and 20Gbps link layer testing. It’s also the foundation for performing USB4 protocol and logical layer conformance. The only solution capable of testing USB4 and USB 3.2 link layer, each compliance option is sold separately allowing users to scale up testing as needed.
