13.1Probing PCI-X Signals

To ease the probing and debug of the PCI-X signals it is recommended to passively probe the PCI-X bus signals with a logic analyzer. This may be accomplished by placing six AMP* Mictor-38 connectors on the board or probing the bus with an interposer card such as the FuturePlus Systems* FS2007 that works with an Agilent Technologies* Logic Analyzer.

For ease of debugging the pin out of the AMP Mictor-38 connectors, the recommended pin-out matches the FuturePlus Systems* configuration setup, which allow ease of viewing the PCI signals on an Agilent Technologies* Logic Analyzer. Refer to the following test equipment that is used for this analysis:

•Two AMP 2-767004-2 surface mount connectors mounted on the target board and routed to the PCI-X Local bus.

•Two Agilent E5346A or E5351A High-Density Adapter Cables from FuturePlus Systems or Agilent Technologies.

•Four logic analyzer PODS.

•FS1104 Software from FuturePlus.

The equivalent for other analyzers may be substituted. A FuturePlus Systems configuration file with the FS1104 product that matches the pinout in Table 31.
