Introduction
How to Use This
Manual
This manual is organized to help you quickly find the information you need.
• Analyzing the PCI Express Bus chapter introduces you to the FS4400 and lists
the minimum equipment required and accessories supplied for PCI Express bus
analysis.
• The State Analysis chapter explains how to configure the FS4400 to perform state
analysis on your PCI Express bus.
• The Transaction Viewer chapter is a brief overview of this application software that
integrates with the FS4400 Protocol Decoder. For more detail on its operation refer
to the FS1150 User manual on the FuturePlus Systems documentation CD.
• The General Information chapter provides information on the operating
characteristics, and cable header pinout for the FS4400 probe.
Definitions
The following terms are used to describe aspects of the PCI Express bus:
• Channel - One differential signal (2 wires).
• PCIe Lane - A pair of differential signals running in opposite directions (4 wires).
• PCIe Link - A bidirectional interface made with two sets of unidirectional signals. A
Link consists of 1, 2, 4, or 8 lanes.
• Link - One direction of a PCIe link. The FS4400 handles 1 or 2 links at a time,
independently. This supports probing of both directions of a PCIe link, or probing of
a pair of unrelated one-direction links. Links may be merged when displayed on the
logic analyzer.
• Lane - One direction of a PCIe lane.
