Figure 55: Two-State Trigger Example
Three-State Triggering
The Arm and Trigger option has three states, Pre-Armed, Armed, and Triggered. You can define
one transition to arm and another to trigger. This allows you to specify a condition for arming the
analyzer and a second condition for stopping the analyzer. You can use the
Timeout template to
specify a time-out value for the Trigger.
The Arm, Trigger or Rollback option has three states, Pre-Armed, Armed, and Triggered. The user
selects one transition to arm then another to trigger along with an else if transition for the rollback,
which resets the capture to Pre-Armed. This allows you to set a condition that causes the Xgig
Analyzer to go back to waiting for an Arm condition if the selected rollback event occurs. You can
use the
Timeout template to specify a time-out value for the Trigger or the Rollback Condition.
You can use the Timer template for the Trigger or the Rollback but not both.
You can select and define trigger or rollback conditions. You may use any or all of the Bit Errors
as triggers. You can trigger on an ordered set, primitive, or a frame by highlighting the Arm state’s
Trigger or Rollback transition bubble and dragging a template from the
Available Templates
Browser
tree into the
Wait For Any Of These/And NOT These
panes of the Transition Editor. To
define a specific frame or frame type that you want to trigger on, you may drag Any Frame from
the
Viavi Library
folder to the
User Library
folder and double-click it to change its content using
the Template Editor . Finally, you can rename the template by right-clicking it and selecting
Rename
.
