Transmitter Testing and Debug

QPHY-USB3.2-Tx-Rx offers a fully automated test package for USB 3.2 transmitter compliance testing, characterization, and debug. With QPHY-USB3.2-Tx-Rx USB 3.2 testing can be performed on both Gen1 (5 Gb/s) and Gen2 (10 Gb/s) devices under test according to the latest USB 3.2 specifications.

QPHY-USB3.2-Tx-Rx can control the PeRT3 communication with the DUT on the protocol layer by sending a specific number of Ping.LFPS commands in order to stimulate it to output the required CPs for each test. This enables fully automated transmitter compliance testing.

SigTest is the official software written by the USB-IF for compliance testing. By integrating SigTest into QPHY-USB3.2-Tx-Rx pre-compliance testing can be confidently performed prior to attending a USB-IF workshop. QPHY will automatically pass waveforms to SigTest and incorporate the results in the complete QualiPHY report.

SDAIII-CompleteLinQ is capable of simultaneously analyzing multiple lanes. Four “lanes” of analysis are available, allowing users to analyze data streams from different locations in their USB channel(s). For example, Lane 1 can show the Tx output, Lane 2 can show the signal at the far end of an emulated channel, Lane 3 can show the equalized far end signal, and Lane 4 the far end signal with a different CTLE/DFE equalization scheme.

Receiver Tolerance Test

PeRT3 Phoenix System is the first protocol aware receiver test solution for USB 3.2 Gen2 (10 Gb/s). At 10 Gb/s, USB3.1 uses a more efficient data encoding scheme and delivers more than twice the effective data rate of USB 3.0, presenting new challenges in receiver testing. The Teledyne LeCroy PeRT3 Phoenix System simplifies these challenges.

All signal source and jitter parameters can be swept during BER testing. For example, by sweeping the de-emphasis and pre-shoot values, the user can identify the optimized equalization window. Each connect sequence provides the user with a list of options to customize the test criteria and debugging conditions. Pass/Fail information is plotted against the stress parameters under test. See what happened for every test case — in real-time.

PeRT3 Phoenix System supports all the jitter and equalization generation required of USB 3.2, as well as the protocol level handshake that is critical to put the device under test into proper test modes and optimal equalization conditions. PeRT3 Phoenix System also offers true SKP symbol injections and SKP filtering during BER testing, as well as 128b/132b pattern generation and detection.

With a single integrated system, the PeRT3 replaces up to 6–8 other instruments. PeRT3 greatly simplifies experimental setup, increases the ease of designing and conducting fully automated testing. It provides specific test suites to ensure receiver compliance to USB 3.2 specifications. The simple, intuitive interface for creating automated test scripts can, with a few clicks, set up automated tests that initialize the DUT and record error rates while sweeping through any user defined range of jitter parameters.

Protocol Compliance Testing and Verification

The USB Voyager systems provide users with a multifunction platform with integrated exerciser. The Voyager currently supports the Type-C, 3.1 and Power Delivery 2.0 specifications providing the industry’s comprehensive solution for testing next-generation USB devices and systems.

Analyzer supports capture of Power Delivery protocol over the CC wire in USB Type-CTM cables. By utilizing the Exerciser users have the ability to emulate both Sink and Source behaviors. The Power Tracker option provides a time based graphical display of VBus measurements of voltage, current and power.

Utilizing the Voyager with integrated Exerciser and the USB Compliance Suite, users gain comprehensive link layer test coverage to verify hosts and devices properly implement link training, link recovery and power management behaviors. The USB Voyager is a certified Link Verification System (LVS) used at official Compliance Workshops.

The USB Software Suite boasts numerous views and reports including error and traffic summaries, bus utilization, LTSSM and detail views. Software includes comprehensive Device Decoding - SCSI Mass Storage, Hub, PTP, MTP and all popular USB device classes.
