Digital retiming is currently supported in FC, GE and SAS/SATA Analyzer ports. For SAS/SATA
Analyzer ports, Digital Retime is only available for the 6G Wide-Port and Narrow Blades and the
LX and LXP fixed-port systems. The Xgig5000 16G FC blade only supports Digital Retime.
However, the Xgig1000 systems with 16G FC functionality support Digital Retime and Analog
Passthrough, and the Xgig1000 PCIe system supports Analog Passthrough only.
The signal regeneration option is set for each port-pair or link.
Warning: Changing the signal regeneration from Analog Passthrough to Digital Retime may
cause loss of data on the network.
When you have a configuration that is different from the current hardware settings, a warning

Multiplexing for SAS/SATA
Multiplexing is only supported for analog passthrough in SAS/SATA. To analyze multiplexed
signals, select the ports that have multiplexed signals and choose the
Multiplexed
for the 6G SAS/SATA blades and systems.
SAS/SATA Multiplexing in the analyzer context means that the analyzer ports will be able to
correctly interpret and decode the signal when two logical links exist within a single physical link
(port-pair). The Dwords for each logical link are interleaved on the wire.
The logical links within a multiplexed signal can be analyzed as with any other link within the
analyzer. For example, you can trigger or search on the data contained within a single logical link
that is being transmitted within a multiplexed signal. Domains within TraceControl are still
comprised of physical ports selected in the

Segments
twice the number of buffer segments and half the buffer size per logical port.
If multiplexing is enabled for a state machine, the ports appear in the
Template
port name to indicate the logical link. You can select or deselect the checkbox for a link to choose
which logical link you want to trigger on.
