Fibre Channel Compliance Theory
The Fibre Channel Compliance Tool utilizes the Known Pattern with Marker tool for the measurements. In
addition to the data signal to be analyzed, this tool requires a pattern marker to be connected to the Arm
Channel. If your SIA-3000 is equipped with the PM-50 option, the marker signal will be generated on the
card and no additional input signals are required for making a measurement. The Marker signal has an
edge relative to the same bit of the pattern each time the marker occurs. Since no bit-clock is used,
analysis of jitter is independent of clock-jitter effects, and because the Arm is not a trigger, any jitter on
the marker will not transfer to the measurement of the Data.
For an in depth description on Known Pattern with Marker Measurement Theory, refer to the Known
Pattern With Marker quick reference guide.
