Signal Regeneration
The signal can be digitally retimed. See
about signal regeneration settings. Select the

Digital retiming is currently supported in FC, GE (except 40G Ethernet) and SAS/SATA Analyzer

Warning: Changing the signal regeneration between Analog Passthrough and Digital Retime
may cause loss of data on the network. Changing the link speed when the signal is digitally
retimed may also cause data loss.
Scrambling
This setting applies only to the 8G Fibre Channel ports and PCIe ports. However, the scrambling
setting for PCIe ports is on the

When capturing data using analyzer ports on the Xgig1000 with 16G FC functionality, you can set
the link speed so that the capture will include or not include scrambled data. By default, scrambled
data is turned on for 8.2500 Gbps captures and turned off for 4.2500 Gbps captures.
If you toggle between the scrambling and the non-scrambling mode for the same link speed, you
will not get a warning message since scrambling does not affect the data path but only how the
data is written to the buffer.
