Sierra M6‐2 SAS/SATA Protocol Analyzer User Manual 345
Port Configuration for InFusion Teledyne LeCroy
 JA (Host Side): Analyzer captures Host to Jammer and Jammer to Host. Analyzer
is before and after Jammer on Host side. See Figure 4.8.
Figure 4.8: Jammer and Analyzer Host Side
 JA (Device Side): Analyzer captures Jammer to Device and Device to Jammer.
Analyzer is before and after Jammer on Device side. See Figure 4.9.

The setup options are the same whether Jammer modifies traffic from Host to Device or
from Device to Host.
Note: When the Unit Under Test (UUT) is the Host, using JA (Host Side) (see Figure 4.8) will give the
most accurate recordings of Host behavior, though the Jammer delays will accumulate in the
round trip.
Note:
When the Unit Under Test (UUT) is the Device, using JA (Device Side) (see Figure 4.9) will give the
most accurate recordings of Device behavior, though the Jammer delays will accumulate in the
round trip.
Note: The After Jammer configuration (see Figure 4.7 ) is useful when debugging a system, as the
tapping points are balanced to account for Jammer delays. Note that when SATA traffic is
recorded, this configuration might show out of order HOLD/HOLDA primitives, due to the special
handling of these primitives by the Jammer.
Note: When running InFusion in an AJ port configuration a "FIS Signalling Latency Error" message
displays due to the delay through the InFusion Jammer. This can prevented by turning off the
detection of this error using the Protocol Error Mask dialog from the Settings tab.
