Figure 2.71: 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 when a trigger occurs. Under Setup
select External Trig Setting to choose 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.
