The FS4320 Fibre Channel Protocol Analysis Probe provides two functions:
1) Provides an electrical and mechanical interface from up to 6 Fibre Channel
optical links to an Agilent Technologies logic analyzer
2) Provides software to set up the Agilent logic analyzer and to allow powerful
protocol analysis of the Fibre Channel transactions.
Protocol Analysis Mode
The software included with the FS4320 contains complete configuration files
and a FuturePlus Fibre Channel Protocol Decoder for your Agilent logic analyzer.
The Agilent logic analyzer is used in state analysis mode, where the analyzer
master clock is derived from the Fibre Channel Protocol. The Fibre Channel
serial data is converted to parallel data in the analysis probe. This allows
easy triggering, store qualification and performance monitoring of the Fibre
Channel. The FS4320 Protocol Decoder translates the incoming data into a readable
display that lists the Fibre Channel format of Header, Payload, and CRC.
Triggering, Filtering and Store Qualification
The Agilent logic analyzer may be triggered or qualified on any of the ordered
sets such as SOFx, EOFx, IDLE, etc. Additionally, triggering on frame header
fields, such as Frame Type, the Source Node ID, or the Destination Node ID
is possible. Predefined condensed acquisition modes can be chosen to prevent
Idles and recurring Primitive Sequences from being acquired, thus saving
trace memory and providing an easier to read state display.
The FS4320 Fibre Channel Analysis Probe accepts 6 pairs of fibre optic
cable. Each pair consists of a fibre that carries data to the analysis
probe (the input or receive fibre) and a fibre that carries data from
the analysis probe (the output or transmit fibre). The data must conform
to the Fibre Channel FC0 and FC1 layers (physical and signaling). The
analysis probe converts the data in each Receive fibre to electrical
signals and de-multiplexes the bit-serial data to a 32 bit parallel representation.
The parallel data and other signals are made available on the front panel
for connection to an Agilent logic analyzer. Probe generated control
signals are available on separate connectors, one set of optional signals
for each three input fibres. Some of these signals are necessary for
protocol decode, and others carry information that is associated with
the input fibres passed in through a rear-panel connector from other
user provided sources.
Cross-Domain Analysis
Are you analyzing data in multiple domains? Simply use this analysis probe
to monitor a Fibre Channel link, and then use another FuturePlus Systems
analysis probe to monitor other buses. We have analysis probes for many other
buses, including AGP, PCI, ISA, VME, VXI, PMC, SCSI, USB, Rambus, DIMM and
SIMM. You can create your own custom measurement system, trigger between
buses, and view data from multiple buses simultaneously in the same display.
In a similar fashion, you could connect an analysis probe for your host processor
to another logic analyzer card.
