Note Using the Active-High setting requires care because the Trigger Input signals on
external interface board are pulled up internally in the Analyzer. Your External
Trigger source should drive the input signal low before starting recording or the
Analyzer will immediately detect a Trigger Event due to the signal pull-ups.
Actions Recording Options
Use the Actions screen to set the Trigger, Filter Out/In, Restart, and Count
options that define the rules for data recording sessions.
The Restart and Count options allow you to configure and control the order in
which selected events trigger the Analyzer or filter the recording and to begin the
sequencing again.
Click the Actions tab on the Recording Options screen.
The Actions screen provides a graphic representation of the ways in which events
selected on the Event Groups screen are used during recording. The screen is
roughly divided into three fields:
• The field on the right displays the Trigger, Filter Out/In, and Restart Action
buttons, which are always present.
• The field in the center displays two Count Action buttons, which are always
present.
• The field on the left displays Event buttons representing any Events (Packet
Identifier, Token Patterns, and so on) you selected from the Event Groups list
on the Events Recording Options screen. Their presence is tied directly to
your selections.
