Warning: The Voyager M4120 Power Delivery (PD) Exerciser allows the customer to set Voltages and Current levels to be delivered to/from Devices and Hosts and their connecting cables which may exceed their capabilities.
-
This can cause damage to the devices under test and their cables. Use caution when writing scripts so that these limitations are not exceeded.
-
Power-cycle the M4120 unit after PD usage to insure that the go back to their default Voltage and Current states.
The Voyager M4120 is a USB4 v2 protocol analyzer designed to capture and analyze all forms of USB4, including USB4 120 Gbps Asymmetric Link operation. It provides high-fidelity acquisition and deep protocol visibility into Gen 2, Gen 3, and Gen 4 traffic—from link training to tunneled flows—using Teledyne LeCroy’s T.A.P.6™ technology. The Voyager M4120 also offers backward compatibility and broad protocol coverage that includes USB 2.0, USB 3.2, Thunderbolt™ 3-5, and USB Power Delivery 3.2 (EPR).
See the Release Notes for the latest on host machine requirements and supported operating systems.
USB4, USB 3.2, and USB 2.0 Features
The system can monitor traffic between USB 2.0 links using standard high-speed compliant cables. USB 3.2 SS Gen 1 (5Gbps) and USB 3.2 SS+ Gen 2 (10Gbps) links require using compliant USB Type-C™ connector cables. USB4 requires USB4-compliant cables.
If configured for USB4 testing, the system supports monitoring between links using USB4 Type-C™ connector cables. Analysis of 80 Gbps traffic requires the use of short, low-loss, high quality cables, as provided by Teledyne LeCroy with your M4120 product. Use of other cables may compromise the signal quality and prevent capturing of the traffic. Electronically Marked cables may be used in either of the connectors marked “Left” and “Right”. The E-Marked cable should be connected to the Downstream Facing Port (typically a host connector), as opposed to an Upstream Facing Port, to allow for Alt-Mode negotiation.
