A single differential pair (two signals) that transmit data in one direction of a PCI Express Link. A unidirectional lane. Printed circuit board System under test. This is the system/circuit board(s) you intend to test with the serial analyzer. P6700 Series Serial Analyzer Probes Instruction Manual...
Getting Started Product Description Tektronix offers three types of probes for the TLA7S08 and TLA7S16 Serial Analyzer modules: Midbus probes Slot interposer probes Solder-down probes Midbus Probes A midbus probe connects to a retention mechanism installed on your circuit board.
A slot interposer probe connects to a PCI Express slot on your SUT. Each probe has a x16 connector for a PCI Express card device. Tektronix offers the following (bidirectional) slot interposer probes: P6701S PCI Express x1 Slot Interposer probe...
(P75TLRST). Up to four probes (one differential pair each) can be installed in Probe each signal connector to the serial module. (See page 61, Adding Probes to the P6701SD Probe Connector.) Figure 3: P6701SD Solder-Down probe P6700 Series Serial Analyzer Probes Instruction Manual...
Choose one or the other, based on the footprint on your platform. To capture signals from a bidirectional X16 link, you will need two serial analyzer modules connected to a slot interposer probe. (See page 12, Connecting a Probe to a Bidirectional X16 Link.) P6700 Series Serial Analyzer Probes Instruction Manual...
3. Insert the retention mechanism into the holes in the footprint on the PCB. NOTE. The following two steps are important to ensure that the retention mechanism is correctly mounted and that the probe makes proper contact with the PCB. P6700 Series Serial Analyzer Probes Instruction Manual...

This section provides guidelines for designing a system to be tested with a P6700 series probe(s). Probe Dimensions The following figure shows dimensions of the P6700 series probes. Both the P6708 and P6716 have the same cable lengths. Figure 14: P6716S dimensions...

Immersion gold over nickel (immersion silver and hot air solder level (HASL) also acceptable) NOTE. Tektronix recommends that the holes made for the retention mechanism posts remain unconnected to a ground plane. This prevents overheating the ground plane and promotes quicker soldering of the retention posts to your PCB.
NOTE. The via hole size in the following table is a minimum size, based on the assumption that the circuit board is 2.36 mm (0.093-inch) thick. P6700 Series Serial Analyzer Probes Instruction Manual...
The solid white pads shown in the diagram are the ground pads. Figure 22: Recommended trace routing on primary surface layer Tektronix recommends that you design your footprint so that there are no traces or vias in the two spaces designated in the following diagram. If your design requires the use of these two spaces, Tektronix recommends that you fully solder mask these areas.
