Chapter 4, Xgig TraceControl Capture Configuration
General Settings

Xgig Analyzer User’s Guide
Select the
Digital Retime
option in the TraceControl Configuration Editor to retransmit the signal
using the analyzer's clock. Jitter is eliminated and fill characters are added or deleted in
compliance with the specification of the network data.
The default option is
Analog Passthrough
. The received signal is buffered and retransmitted
unmodified. The signal is amplified and link jitter is increased by <100psec. An
Analog
Passthrough Multiplexed
option is available for Analog Passthrough when analyzing SAS/
SATA. See
“Multiplexing for SAS/SATA” on page 100
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.
When you have a configuration that is different from the current hardware settings, a warning
message appears. Press
Change
to proceed with the signal regeneration or link speed change and
send the new configuration to the hardware. Check the
Always overwrite the hardware settings
with the configuration and do not display this dialog again
box to stop receiving this warning
message. Use the Options dialog in the
Tools > Options
menu to directly set the option for this
dialog box. See Figure 47 above.
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
Analog Passthrough
Multiplexed
option from the
Signal Regeneration
drop-down menu. This option is only available
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
Domain Creation Dialog
box.
Setting the
Analog Passthrough Multiplexed
option affects the
Trace Size
and
Number of
Segments
options. Multiplexed signals are separated into two logical links, and therefore require
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
Ports Selection for Current
Template
section of the Capture Filter and Transition Editors with a zero or a one following the
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.
Warning:
Changing the signal regeneration from Analog Passthrough to Digital Retime may
cause loss of data on the network.
