Reports with Margin Analysis

In addition to providing you with

measurement results, the PCI Express

electrical test software provides a report

format that shows you not only where your

product passes or fails, but also reports

how close you are to the limits specified

for a particular test assertion. You can

select the margin test report parameter,

which means you can specify the level at

which warnings are issued to alert you

to electrical tests where your product is

operating close to the official test limit

defined by the PCI Express 2.0, 1.0a or 1.1

specifications.

Figure 9. The PCI Express electrical test software results report documents your test, indicates the

pass/fail status, the test specification range, the measured values, and shows how much margin

you have.

Figure 10. The HTML report provides additional details including test setup conditions, graphical results,

and test limits (where appropriate).
