You can easily add an analyzer to the configuration above by placing it between the SAS
InFusion box and the DUT or the box and the host controller.

Connection
with
Analyzer: 2
Channel
Configura-
tion
With a two channel analyzer, you can set up the analyzer so that it records traffic before
and after modification by the SASInFusion box (Figure 17).
The host controller sends unmodified traffic to the analyzer. The traffic is recorded by the
analyzer and then sent to the SASInFusion box where it is modified. Afterwards, the
modified traffic is looped back into a second channel on the analyzer and recorded again.
From there, the traffic passes back through to the device. The result will be a
two-channel recording.

ions using
"Octopus"
Cables
To use internal "octopus" cables with the SAS InFusion box you will also need to use
LeCroy-provided junction boards and two external SATA cables.
Junction boards function as an interconnect between the external cables and the octopus
cables.
