PETracer Summit or Summit T2-16 Bit Tracer Recording
Note: For more information, see BitTracer Recording “Link Configuration” on page 167.
Link Width: Sets the physical width of the link. (The Auto option is not available for
Bit Tracer Recording.)
Upstream and Downstream: Gives you low-level control over each link direction. The
heading for these boxes indicates the port and/or unit to which the following options are
applied based on the current Analyzer configuration:
• Inhibit Channel: See above.
• Reverse Lanes: See above.
• Invert Polarity: See above.
Use External Reference Clock: If the PCI Express link under analysis uses
spread-spectrum clocking, then the Analyzer must use the external reference clock from
the host machine. If the host machine does not supply a reference clock, the internal
reference clock in the Analyzer module is used instead for link analysis

(Not available for Bit Tracer Recording.) Only the standard PCIe reference clock is
supported.
