Teledyne LeCroy Port Configuration for InFusion
344 Sierra M6‐4 SAS/SATA Protocol Analyzer User Manual
 JA (Host Side): Analyzer captures Host to Jammer and Jammer to Host. Ana‐
lyzer is before and after Jammer on Host side. See
Figure 4.10 .
Figure 4.10: 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 4.11 .

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 4.10 ) will give the
most accurate recordings of Host behavior, though the Jammer delays will accumulate in the
round trip. When the Unit Under Test (UUT) is the Device, using JA (Device Side) (see
Figure 4.11 ) will give the most accurate recordings of Device behavior, though the Jammer
delays will accumulate in the round trip. The After Jammer configuration (see Figure 4.9 on
page 343 ) 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.
