Scenario Actions Teledyne LeCroy
However, in the case of combined events and/or actions, the separate counters provide
flexibility in designing test cases. For example, consider the case where Event_1 OR
Event_2 leads to Action. If Event_1 has a counter of 5, then the Action triggers either
when Event_1 has repeated five times or when Event_2 happens the first time, whichever
occurs first.
But if the event counters are set to 1 and the Action counter is set to 5, then the Action
happens after five occurrences of EITHER Event_1 or Event_2.
Capturing a Data DWORD
InFusion provides the ability to capture individual data DWORDs and provides four
different registers to store captured DWORDs (DWORD #0, #1, #2 and #3).
To capture a data dword, select Capture Data DWORD from the Action Properties screen,
as shown below. Select the register to be used to store the DWORD from the drop ‐ down
menu under the Capture Register property.

Using Captured Data DWORDs
Captured data DWORDs can be used in creating events for data that match the captured
DWORD(s), or in creating actions to substitute the captured DWORD(s) into the data
stream.
To create an event using the captured DWORD, in the Event Properties menu (see
Figure 4.21 on page 396 ), select SAS Data Pattern (or SATA Data Pattern ), and then select
any of the 12 DWORDs ( DWORD 0 Type through DWORD 11 Type ). The drop ‐ down menu
provides the choice of a custom DWORD or any of the four captured DWORDs. If you
select a captured DWORD, the
Value field beneath this selection is hidden (the Value field
