The Trigger Tab
• OR Trigger
When the logic analyzer is armed by another instrument (as specified in
the Intermodule window), this trigger function becomes true when a
pattern occurs a specified number of times OR when the arm signal is
received.
See Also “To specify a label pattern event” on page 66
“To specify a label edge event” on page 66
“To break down a trigger function” on page 67

General State Trigger Functions
The following general trigger functions are found in the Trigger
Functions tab when the logic analyzer is in the state sampling mode.
You can edit most of the trigger functions to specify particular pattern
events.
You can break down a trigger function to see how many advanced
sequence levels are used.
• Find pattern n times
Becomes true when the specified pattern occurs in the specified number
of samples (eventually).
• Store range until pattern occurs
Becomes true when the specified pattern occurs in the specified number
of samples (eventually) and only stores samples in the specified range
until then.
• Store pattern2 until pattern1 occurs
Becomes true when the first specified pattern occurs in the specified
number of samples (eventually) and only stores samples with the second
specified pattern until then.
• While storing pattern2, find pattern1
