12 Summit T24 PCI Express Multi‐Lane Protocol Analyzer User Manual
Summit T24 Components
Summit T24 components used in the installation are:
 iPass x4 to x8 Straight cable: The cable supports four lanes from two directions
but allows connection to x8 iPass connectors. The smaller x4 end plugs into the
Summit T24 and the larger end plugs into the interposer
 Summit T24 x4 Slot Gen2 Passive Interposer: The slot Interposer provides the
point of attachment for the Analyzer to the Device Under Test (DUT). The Inter‐
poser is designed to fit between a motherboard and one of its device cards ‐ for
example, a LAN card. The Interposer has three sets of connectors: a gold male
connector that fits into a standard x4 up to x16 PCI Express slot on a mother‐
board, a PCIe female connector that accepts any PCI Express add in card.
Although the PCIe female connector will accept up to x16 male connectors, only
four lanes will be passed through the x4 interposer.
Note: If using X8 or X16 interposers, lane width reducers may be needed to analyze the link.
Installing the Gen2 Passive Interposer
To install the Interposer, perform the following steps.
1. Insert the gold male connector on the Interposer probe into a x4, x8 or
x16 PCI Express slot in the motherboard. If a X1 link is required, use edge adaptor
for x1.
2. Insert the PCI Express DUT into the Interposer’s PCIe female device connector.
3. The slot Interposer is shipped from Teledyne LeCroy with a metal face plate for
attachment to a PC case. If you are working with a motherboard that is not in a PC
case, you may prefer to remove the metal face plate so the Interposer can sit flat
with the motherboard. To remove the face plate, unscrew the two screws that hold
it onto the Interposer
Power On Analyzer and then DUT
1. Power on the Summit T24 Analyzer.
2. Power on the DUT.
3. Open the PETracer software on the host machine. The Analyzer is now ready for
PCI Express traffic recording.
