100 Sierra M122 SAS/SATA Protocol Analyzer User Manual
Pack training sequence
Checking this option allows hiding the details of the Training Sequence, which can take up
large portions of the trace unless packed.
ALIGN Transmission Period (differs for SAS and SATA)
Choose the ALIGN Transmission Period for SSP and STP by clicking the corresponding
option button, then open the Protocol Error Mask dialog.
Protocol Error Mask
Click the Protocol Error Mask button to open the Protocol Error Mask dialog.
Figure 2.70: Protocol Errors Dialog
Check the Protocol Errors that you want the Analyzer to ignore.
When “RD Error” and “Code violation Error” are set as trigger events: 
“RD Error” or “Code violation Error” can occur right after the OOB sequence.
“RD Error” or “Code violation Error” can occur right after the recovery from the PM state.
These errors are mainly caused by the long synchronization time of the analyzer. If these
errors, caused by the Analyzer, become triggers, you cannot detect some other errors
that you really need to detect. To NOT detect the above two errors, enable the software
setting Disable ‘Disparity Error’ and ‘Symbol Violation’ during Speed negotiation. After
this, the code violation is not triggered during the speed negotiation phase, but is
triggered if the violation happens after the speed negotiation phase.
External Trig Out Setting
The Analyzer can send a Low or High external signal anytime a trigger occurs. Select the
External Trig Out Setting: High Active, Low Active, or Toggle from High to Low or Low to
High once (3.3 V output). Enter the External TrigOut pulse width.
The pulse width is programmable in the software. The Voltage level is 0 to +3.3 Volt. The
trigger out is derived by NL17SZ126 buffer. The delay for OOB traffic external trigger out
is 190 ns. The delays for non OOB external trigger out are:
 12G ~ 380 ns
