March 26, 2015 – Teledyne LeCroy Korea (Country Manager Woon-Jae Lee, teledynelecroy.co.kr) today announced the QPHY-USB3.1-Tx-Rx package, a special USB 3.1 test suite for automated USB 3.1 transmitter (Tx) and receiver (Rx) compliance testing, characterization, and debugging. In accordance with the recently announced USB 3.1 specifications, both Gen 1 (5Gbps) and Gen 2 (10Gbps) devices can be measured using the newly announced USB 3.1 test tool package. Tx testing is performed using a high-bandwidth 16 GHz oscilloscope, while Rx testing is performed using the PeRT3 (Protocol Enabled Receiver and Transmitter Tolerance Tester). The new QPHY-USB3.1-Tx-Rx software is a tool based on the Qualiphy automated test framework, which provides measurement diagrams, automatic oscilloscope operation, and automatic test report generation.

Integrated Transmitter/Receiver Test Solution

The powerful specifications of Teledyne LeCroy oscilloscopes are combined with the special specifications of PeRt3 to create an integrated Tx/Rx solution. For example, QPHY-USB3.1-Tx-Rx software fully automates Tx testing by requiring the DUT to change the compliance pattern for each test, and the receiver calibration process is fully automated through direct communication between the oscilloscope and PeRt3. This combination simplifies the testing process and saves time. QPHY-USB3.1 Tx-Rx software provides a single unified interface for performing both Tx and Rx testing. Competitive solutions require different test environments, complexes, and multi-equipment setups, which complicate the testing process and add costs.

Beyond USB 3.1 Physical Layer Test

Teledyne LeCroy is the only provider of a complete USB 3.1 test solution capable of handling transmitter, receiver, protocol, and cable/connector compliance testing, characterization, and debugging. All USB 3.1 testing can be completed on Teledyne LeCroy equipment capable of securing and supporting all devices. In addition to the transmitter/receiver test solution, the test suite includes the Voyager M310C protocol analyzer and the SPARQ network analyzer.

The Voyager M310C is a platform equipped with the USB Exerciser option that can emulate both host and device at transfer speeds of up to 10 Gbps, allowing users to generate and send user-defined packets by inserting headers, payloads, timings, link conditions, and errors. The Voyager M310C supports a Type-C connector and power delivery in analyzer and exerciser modes, allowing it to be used as a sink, such as a power source or power delivery endpoint.

The Teledyne LeCroy SPARQ signal integrity network analyzer can be used to measure insertion loss, impedance, and crosstalk in USB 3/1 transmitters, receivers, and cables. SPARQ is a TDR/TDT-based analyzer that is lower in price than a VNA and allows for easy S-parameter measurement with just a single button.

Teledyne LeCroy's USB 3.1 test solution ensures support for development, debugging, and compliance at every stage.
