QPHY-PCIE3-TxRx 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-TxRx 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
If using a PeRT3 device with an oscilloscope, set it below the oscilloscope to keep the
connection cable length as short as possible.
See the description of each test configuration for specific set up information.
QPHY-PCIE3-TxRx 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.
Demo Add-in Card Tx
This configuration runs all transmitter tests using saved waveforms located on the oscilloscope
in the D:\Waveforms\PCIE3\TX\Demo directory on the oscilloscope. It is meant to easily
demonstrate the QPHY-PCIE3-TxRx capabilities when live signals cannot be tested.
You can also select saved waveforms to be used in the demo. The files must be named:
“"M1_L_DEMO_8G_Ln0_P7_00000.trc"” and "M2_L_DEMO_8G_Ln0_P7_00000.trc” and
placed in the folder path above.
