"USB 3.0 introduces low latency flow control and aggressive power management policies that will require thorough testing as part of the USB 3.0 compliance program," says Jim Kuo, Senior Digital Design Manager at JMicron. "LeCroy's Voyager verification system provides visibility to the logical SuperSpeed packets. The Exerciser option gives us precise link layer control, allowing us to test marginal timing conditions that simply can't be done using a real USB 3.0 host controller."
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(TM) 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.
"SuperSpeed USB presents developers with certain new challenges posed by the significantly greater speed and more complex features," said Graef. "LeCroy is the first to provide a single-source comprehensive SuperSpeed USB test suite solution that addresses the increasingly sophisticated measurement and analysis capabilities that are required."
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.
