Chestnut Ridge, New YorkImagine one-button high-speed serial data compliance testing. If you can, check out this product from oscilloscope and test equipment maker LeCroy Corp.. It's introducing a hardware and software serial data compliance package called QualiPHY that can do just that.
For use with any of LeCroy's 2-GHz bandwidth (or higher) digital oscilloscopes, QualiPHY is for high-speed data applications such as SATA, FB-DIMM, UWB, ENET, USB, PCI Express, SAS, or HDMI. It makes optimum use of the company's fixtures, oscilloscopes, and scope probes.
QualiPHY establishes a highly-automated compliance test tool for developing and validating the PHY (electrical or physical layer) of a device, in accordance with the official documents published by the applicable standards organizations and SIGs (special interest groups).
QualiPHY is a Windows-based application designed with a common intuitive GUI (graphical user interface) across the industry's most popular serial data standards. It will run from one test to as many as all tests for any standard. Just push one button and watch the green bars to completion.
According to LeCroy filed application engineer Mike Hertz, QualiPHY leverages the expertise of his company's Protocol Solutions Group to provide this best-in-class compliance test. What's more, Hertz emphasizes that these tests are standards-certified and validated.
Addressing a variety of compliance test needs, QualiPHY offers complete automation for system level and pre-production tests. Hertz points out that his product ensures that all tests are standards-certified and validated, which will ensure success at official testing events and plugfests. QualiPHY compliance tests are PHY layer applications, yet they leverage protocol approaches with true traffic emulation and test-pattern generation.
Hertz also notes that QualipHY lets users configure limits for margin testing and fixture/probe de-embedding as required by a specific design.
QualiPHY was also developed with the global design environment in mind. For example, a dispersed development team can conduct tests anywhere in the world using IEEE-488/GPIB (General Purpose Interface Bus) or LAN/WAN connections (with an applicable oscilloscope, of course).
Using the Web, team members can also access live signals from oscilloscopes in remote locations. A LeCroy scope can act as both a data-acq system and a controller. You can run Windows either on the scope or on your PC, using GPIB as the cross-over.
Supporting LeCroy's compliance test packages, QualiPHY can be added to any of the firm's realtime or sampling scopes (with 2-GHz or more of bandwidth). It can also be used with LeCroy protocol analyzers, test fixtures, and probes for specific standard configurations.
QualiPHY also complements other tools used with LeCroy instruments, such as the company's D11000PS High Bandwidth Probing System, Jitter Wizard, filtered jitter measurements, and custom PLL (phase locked loop) configurations.
Naturally, measurement results need to be summarized and tabulated. QualiPHY goes beyond that by incorporating an application framework in which every experimental result can be saved to an XML-formatted record.
Test reports contain tabulated numerical values for each individual test result. That can be beneficial to IC developers who require comprehensive wafer/die characterization to define parametric performance and establish device performance capability. It can also be of benefit to system-level validation teams working in parallel development cycles that need to combine, study and interpret performance data and correlate test results with prior runs.
Likewise, manufacturing/production test environments can use these reports in which key performance parameters are monitored using control charts or other in-process indicators of product/process performance.
Finally, QualiPHY offers a choice of automatic, HTML, .PDF, or .RTF report generation formats. These various formats make sure your docs look good!
Low To Medium Speed Interfaces
For users with cost-driven product development constraints, LeCroy's recently-introduced SDA 3010 serial data analyzer brings QualiPHY's automation to low to medium-speed serial data interfaces, such as USB 2.0 and Ethernet 10/100/1000 Base-T applications.
Equipped with 20 million points/channel, 3-GHz bandwidth, and sample rates up to 20-Gsamples/s (on two channels; 10-Gsamples/s on four), the company's SDA 3010 comes with jitter analysis and debugging tools typically found in high-performance serial data analyzers, yet at a lower cost. The SDA 3010 is priced at about $34,500, but includes QualiPHY for USB 2.0 and Ethernet (that's a $6000 value).
For its part, QualiPHY also promises to be cost-effective. You can purchase only the modules you need, when you need them. You use hardware you already own.
Initially, LeCroy is offering modules for Ultra Wideband, SATA, and FB-DIMM applications. These will be followed by modules supporting compliance testing of PCI Express, SAS, Ethernet, and USB. Eventually, LeCroy will add a module for HDMI high-def video. The table indicates pricing for all of these.
