To define event actions and sequencing:
Step 1
Open the Recording Options dialog.
Step 2
Define event settings on the Events tab. For information about event settings,
please see “Event Options” on page 29.
Step 3 Select the Actions tab.
By default, all events are set up as triggers.
Step 4 Associate events with actions and other events by left-clicking on an event,
then moving the mouse pointer to the desired action or event. A thick, black
arrow will follow the pointer as you drag the mouse. Complete the
connection by clicking on the target action or event.
Step 5 Click OK to apply the settings and close the Recording Options dialog.
Trigger
This action designates an event as a recording trigger. If more than one event is designated
as a trigger, the recording will trigger on the first one that is detected.
Filter
Events can be filtered in or filtered out of a recording. This allows you to focus on just the
packets you're interested in on heavily loaded buses. If Filter Out is selected, packets that
match the events associated with the filter action are excluded from the recording. However,
if Filter In is selected, only the packets that match any of the events specified on the Events
tab will be recorded.
To change the filter polarity:
Step 1
Click on the light blue circle in the upper left of the Filter box.
A menu will pop up.
Step 2
Choose Filter In or Filter Out from the menu.
The name on the Filter box will change to reflect your choice.
Restart
This action works in conjunction with the counters and/or a sequence of two events. When
an event with the Restart action occurs, all the counter values are reset to initial values and
the event sequences are restarted to the “wait for the first event in sequence” state.
Count1 and Count2
The Count action allows the specified events to happen a specified number of times before
the trigger is generated. You can connect several events to a counter. Each time one of these
events comes across the bus, the value of the counter is decreased by one. When the counter
value reaches zero, the trigger is generated. If there are one or more events linked to each
counter, then the trigger will be generated by the first event that causes a counter value to
reach zero.
