Setup:

For System 1, Port 1 of Initiator connects to the Host DUT by a mini-SAS cable. Using Jammer allows
error injection on Port 1. Using Analyzer allows analysis on Port 1 before and after error injection.
For System 1, Port 1 of Target connects to Port 2 of the Initiator port of System 2 by a mini-SAS cable.

For System 2, Port 2 of Initiator connects to Port 1 of the Target port of System 1 by a mini-SAS cable.
For System 2, Port 1 of Target connects to a Device Under Test (DUT 1) by a single octopus cable.
For System 2, Port 2 of Target connects to a Device Under Test (DUT 2) by a single octopus cable.
Using Jammer allows error injection on Port 2. Using Analyzer allows analysis on Port 2 before and after
error injection.

Description:

Port 1 of System 1 is configured to jam the incoming traffic and output it back. In addition, the system
is internally connected so that one analyzer on Port 1 is capturing the incoming (and pre-jammed)
traffic, while another analyzer on Port 1 can capture the outgoing (post-jammed) traffic of physical Port
1.

Port 2 of System 2 is configured to jam the incoming traffic and output it back. In addition, the system
is internally connected so one analyzer on Port 2 is capturing the incoming (and pre-jammed) traffic,
while another analyzer on Port 2 can capture the outgoing (post-jammed) traffic of physical Port 2.

This configuration allows impairing traffic on both physical ports of DUT1 and DUT2, while capturing
pre-jammed and post-jammed traffic on each.

Ports 3 and 4 on both systems are not used.
