LeCroy Corporation Trigger Setup
96 Sierra M6 ‐ 2 SAS/SATA Protocol Analyzer User Manual
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.
External Trig In Setting
An external Low or High input signal can cause triggering. Select the
External Trig In Setting: High Active, Low Active, or Toggle from High to Low or Low to
High once (3.3 V output).
Choose Port Speed
The default speed is Autospeed. You can also select the port speed from the

drop ‐ down list: 1.5 Gbps, 3.0 Gbps, or 6.0 Gbps.
Note:
If a Port ID check box has no check, the analyzer does not capture any patterns for that port. The
system allocates trace memory for that port to its adjacent port, for example: I1, T1 < ‐ > I2, T2.
