Test Modes
E2969-91020
Test Modes
The protocol test card provides three test modes:
• Add-In-Card test mode
• Known Endpoint test mode
• Topology test mode
The test software provides a list of tests for each of these modes. You can
select the mode and execute the tests from the graphical user interface.
NOT E
The current version of the PTC only supports the Add-In-Card test mode
and Topology Test Mode. Known Endpoint test mode will be supported by
one of the next releases.
Add-In-Card Test Mode
In the Add-In-Card test mode, the PTC acts as a switch device between
the target platform and another PCI Express add-in card (DUT). The DUT
is plugged into the PCI Express slot on top of the PTC.
NOT E
Though the upper slot of the PTC is capable of accepting up to x16 cards,
only x1 links are supported.
The tests in this mode check the correct behavior of the add-in card. The
test software communicates with the PTC using PCI Express commands
and performs various tests with the DUT.
In this mode it is necessary to power the PTC through the external power
connector. Any standard ATX Power Supply can be used for this purpose.
