SuperSpeed USB test suite eliminates the need to integrate multiple suppliers’ system components

LeCroy has introduced a single-source lineup of test instruments that comprehensively support the USB (Universal Serial Bus) 3.0 standard. The test suite integrates a selection of test instruments and software that addresses all transmitter, receiver, TDR (time-domain-reflectometer), and protocol tests that the specification currently defines for the cabled, bidirectional, 4.8Gbps USB 3.0 bus, which can transmit data an order of magnitude faster than USB 2.0. Corp

The product line includes the SDA (serial-data-analyzer) 813Zi oscilloscope for PHY (physical)-layer transmitter-compliance verification and debugging; the PERT (protocol-enabled-receiver/transmitter)-tolerance tester for receiver testing; the WaveExpert ultrahigh-bandwidth sampling oscilloscope for critical characterization and TDR measurements; and the first USB 3.0 protocol analyzer-exerciser platform, the Voyager verification system, which addresses the protocol layer. Automated, easy-to-use QualiPHY compliance-test software and USB 3.0 test fixtures enable rapid debugging and provide accuracy and complete compliance testing.

According to the company, PERT the only tool that manages issues such as the insertion and deletion of skip symbols without losing lock during automated-testing programs, thereby enabling correct measurement of BER (bit-error rate). Because the PERT combines into one instrument the capabilities of a signal generator, BER tester, protocol editor, and SDA system, it simultaneously monitors signal integrity and fully characterizes the receiver’s tolerance envelope through the controlled introduction of various types and levels of signal stress, such as increased jitter.

The full-function Voyager system records and analyzes traffic among USB 2.0 and 3.0 devices. The integrated exerciser emulates USB 3.0 device behaviors to enable functional, reliability, and performance testing. The SDA 813Zi with QualiPHY suits physical-level compliance testing and debugging of USB 3.0 transmitters. As the SuperSpeed USB-compliance specification dictates, you can create the eye diagram and measure jitter after equalization at the reference-channel output and thus debug your signals after continuous-time linear equalization and channel emulation.

Unlike the home-brewed test setups that USB 3.0 developers previously had to create, LeCroy’s USB 3.0 test suite integrates high-performance instruments and software from one supplier.
