Notes on Electrical Testing

Troubleshooting Hi-Speed Test Failures

In the Configure tab’s Debug Mode, there are several options that can help

you troubleshoot hi- speed test failures:

• Marker Placement — Lets you manually adjust the markers around the

required packet/pattern before proceeding with the test analysis. When

“MANUAL” is selected, the automated search for the correct

pattern/packet to analyze is turned off.

• Data Eye Test Mode — Lets you perform the eye test without using the

MATLAB scripts. The oscilloscope will form the eye diagram using the

E2688A serial data analysis (SDA) and clock recovery software option.
