The Teledyne LeCroy Gen2 x16 Active Interposer provides an
economical means to probe PCI Express traffic between a host and
PCIe® expansion card. The interposer assures reliable data
transmission while providing 100% capture of all data traffic flowing
through the PCIe slot interface. Connecting the interposer to a
Teledyne LeCroy analyzer allows decoding and display of data flowing
in both directions and across all lanes, and will display data traffic using
the industry-standard CATC Trace™ data display, along with a wide
range of traffic and error reports.
The Gen2 x16 Active Interposer supports data rates of 2.5 GT/s (Gen1)
and 5.0 GT/s (Gen2), and lane widths up to x16 (the PCIe connector on
the card will support PCIe expansion cards up to x16—if a x8, x4 or x1
card is inserted, the connection will automatically negotiate to the lesser
lane width). The interposer can be used with host PCIe expansion slots
as small as x1 by using card edge reducer adapters (see diagram on
following page—again, the connection will automatically negotiate to the
lesser lane width).
The new Gen2 x16 Active Interposer is a powerful and versatile tool for
all developers working with Gen2 PCIe expansion cards.

Connecting the Gen2 x16 Active Interposer
1. Install the Interposer into the host system PCIe connector, using a card edge reducer adapter if needed (for x8, x4
and x1 PCIe slots only).
2. Install the PCIe expansion card under test (DUT) into the connector on the interposer. Note that PCIe expansion
cards with edge connectors up to x16 can fit the connector on the interposer, but if x8, x4 or x1 expansion cards are
inserted, the connection will negotiate to the lesser lane width.
3. Connect 12V DC using the AC adapter supplied with the interposer. Make sure that the AC adapter is turned on.
4. Connect the Summit T3-16 Analyzer (or other compatible Teledyne LeCroy analyzer) to the interposer using one (for
up to x8) or two (for x16) iPass Y-cables, as indicated in the diagram above. The “A” connector goes to “Upstream”.
5. Connect the analyzer to a host machine using the USB 2.0 port on the back panel of the Summit T3-16 analyzer.
6. Install the software on the host machine.
System Compatibility
7. Power on the analyzer.
8. Power on the host system.
9. Use the Teledyne LeCroy software application to monitor, record and view PCI Express
