QPHY-SFI

The Teledyne LeCroy QPHY-SFI solution automates testing for SFI base on the SFF 8431 specifications. The test framework simplifies the test setup and execution of generic and common test requirements such as jitter separation, rise/fall time and transmitter equalization parameters. The guided wizard prompts the user to for specification required patterns and takes the measurements accordingly. The test report includes the test results pass/fail summary, margins and limits, as well as waveforms and measurements used during the test process.

  • Powerful SDA II analysis package helps to find the root cause of failures
10G-100G Ethernet

Challenges with testing 10G Ethernet lay not only in the complexity of the test setup but also the requirement for intuitive troubleshooting tools to solve the high speed induced signal integrity issues such as crosstalk, equalization and deterministic jitter break down. Teledyne LeCroy's total solution for 10G Ethernet covers multiple standards associated with 10G interface with the flexibility to easily upgrade to higher lane density testing and higher bitrate testing for 100G architectures. Combined with QPHY automated test environments, the user can minimize redundant test setups and result collection efforts, and stay more focused on compliance, characterization, and debug testing.

Figure 5: Automated Test Frame Work

QualiPHY is designed to reduce the time and effort needed to perform compliance testing on a wide array of high-speed serial buses. QualiPHY is the most intuitive and efficient tool available for performing serial data compliance testing. Selecting a new standard or test setup is done without leaving the main screen, and the user can start testing with a single button press.

Figure 6: Test Report Generation

Measurement results often need to be summarized and tabulated to quickly verify specifications. This information, together with instrument and signal acquisition/test condition setups, results in a fully documented record. QPHY-SFI streamlines this process by incorporating an automatic HTML report generation engine. The created test reports contain tabulated numerical values for each individual test result, including PASS/FAIL and specification limit columns. Reports can also be saved as PDF, HTML or XML.
