Summit T3-8 Components
Summit T3‐8 components used in the installation are:
 iPass Y‐Cable: The cable supports eight lanes from two directions. Side A of the
probe cable connects to the Upstream port on the Analyzer (on the left in the
photo above), and Side B of the probe cable connects to the Downstream port
(on the right).
 Summit T3‐8 x16 Slot Gen2 Active 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 x16 PCI Express slot on a motherboard, a PCIe
female connector that accepts a x16 PCI Express device, and two Interposer
cable connectors that connect the Interposer to the Analyzer (only one is used).
Note: Edge reducers are required for lane widths less than x16.
Installing the Gen2 Active Interposer
To install the Interposer, perform the following steps.
1. Insert the gold male connector on the Interposer probe into a x16 PCI Express slot in
the motherboard. Use edge adaptors for x1, x4, and x8 slots.
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 the host machine’s enclosure. If you are working with a motherboard
that is not in the host machine’s enclosure, 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
Connecting the Probe Data Cable
x8 recordings require one cable. To connect a single Interposer data cable, connect the
probe data cable to the Interposer card at [7:0]. Connect Side A of the probe cable to the
Upstream [7:0] port on the Analyzer, and connect Side B of the probe cable to the
Downstream [7:0] port.
Power On Analyzer and then DUT
1. Power on the Summit T3‐8 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.
