QPHY-PCIE3 Testing
Test Preparation
Before beginning any test or data acquisition, the oscilloscope should be warmed for at least 20
minutes.
Calibration is automatic under software control and no manual calibration is required. This
procedure will be run again if the temperature of the oscilloscope changes by more than a few
degrees.
Required Test Modes
The QPHY-PCIE3 script requires that you place the DUT in the required test modes. The script
will prompt you to do so before each test, but it is recommended that you ensure the DUT is
capable of being placed in the required test modes before beginning testing.
Physical Setup
See the description of each test configuration for specific set up information.
QPHY-PCIE3 Test Configurations
Test configurations include variable settings, limit sets, and test selections.
For detailed descriptions of calibration and testing, please refer to the Teledyne LeCroy
PCIE Gen3 test procedure on PCISIG.com and the official test specification, PCI Express
Card Electromechanical Specification, Rev. 3.0.
Empty Template
This configuration includes all tests and default variable settings specified in the PCIe3
standard. It is meant to serve as a basis for creating custom configurations. Copy and save it
with a unique name, then follow the steps in
Customizing QualiPHY to modify the new
configuration.
CEM Compliance Eye 8 GT/s (Add-in Card)
This configuration generates the CEM Compliance Eye (without SSC) for a PCI Express Gen3
Add-In Card operating at 8 GT/s. The limit set in use is Compliance Limits. All of the variables
are set to their default settings, except that De-embed Fixture Breakout Channel is set to No
and Product Type is set to Add-In Card. Test 1.4 – Compliance Eye 8 GT/s is performed.
