Logic Analyzer Connectivity
The serial buses have Midbus pads (TMS818 probe) for visibility of SerDes lines using a
pre-processor. Each probing pad provides access to the RX and TX segments of a x1 link.
To access the PCI bus, a Nexus PCI interposer card can be used with Tektronix mictor cables. The card
can be plugged into any PCI edge slot, or in-line with the device under test.
