Single source comprehensive SuperSpeed USB test suite

Serial data test specialist, LeCroy has announced the launch of what is described as 'the industry's first single source lineup' of test instruments to comprehensively support the USB 3.0 standard, also known as SuperSpeed USB.

The LeCroy USB 3.0 Test Suite is an integrated selection of test instruments designed to address all transmitter, receiver, TDR and protocol tests currently defined in the Universal Serial Bus 3.0 specification.

The product line includes: the SDA 813Zi oscilloscope for physical layer transmitter verification, compliance and debug; the protocol-enabled receiver and transmitter tolerance tester, PeRT, for receiver testing; the WaveExpert sampling oscilloscope for critical characterisation and TDR measurements; and the world's first USB 3.0 protocol analyser exerciser platform, the Voyager verification system, addresses the protocol layer.
Automated QualiPHY physical layer compliance software, and USB 3.0 test fixtures are included for rapid debugging and unmatched accuracy as well as full compliance testing.

"Through LeCroy's leadership in oscilloscope and protocol analyzer technology, we have developed the first complete single-source suite of SuperSpeed USB test solutions for developers' physical and protocol layer testing needs," said LeCroy vice president and chief technology officer David Graef. "LeCroy's QualiPHY automated compliance test software is the only solution available that fully integrates transmitter and receiver testing, by simultaneously controlling both the SDA 813Zi oscilloscope and the PeRT to produce a full compliance report with transmitter and receiver results."

According to LeCroy PeRT is the only tool that can manage issues such as the insertion or deletion of SKP symbols without losing lock during automated testing programs and correctly measure BER (bit error rate). Because the PeRT combines the functions and features of a signal generator, bit error rate tester (BERT), protocol editor and serial data analysis system into one instrument, it is able to fully characterise the receiver tolerance envelope through the controlled introduction of various types and levels of signal stress (e.g., increased jitter) while monitoring signal integrity.

In addition, the LeCroy USB 3.0 Test Suite includes the preeminent solution for USB 3.0 compliance verification, the Voyager protocol analyzer exerciser system. A full function analyser, it is capable of recording and analysing traffic between both USB 2.0 or 3.0 devices. The integrated exerciser can emulate USB 3.0 device behaviors to allow functional, reliability, and performance testing.

The SDA 813Zi with QualiPHY USB 3.0 automated compliance test software is the perfect instrument for physical-level compliance testing and debugging of USB 3.0 transmitters. Developers can debug their signal after Continuous Time Linear Equalization (CTLE) and channel emulation by creating the eye diagram and measuring jitter after the reference channel and equalization as required by the SuperSpeed USB Compliance Specification.

Finally, the TDR analysis feature of the LeCroy WaveExpert 100H sampling oscilloscope measures Tx and Rx common mode, and differential mode impedance as required by the USB 3.0 specification. The measurements are integrated into the user interface along with a measurement wizard that guides the user through the set up and calibration process.

LeCroy has ensured that the components of its USB 3.0 Test Suite are as easy to order as they are to use. Test bundles include all necessary software, fixtures and cables, and are available for each of the component tests – transmitter, receiver, transmitter and receiver, TDR and protocol – as well as the all-inclusive USB 3.0 Test Suite. USB developers will find a significant cost savings when purchasing the bundles rather than the individual test instruments.
