The Trigger Tab
This trigger function has been replaced by the "Store range until pattern
occurs" and "Store pattern2 until pattern1 occurs" trigger functions.
• Store nothing until pattern occurs
Becomes true when the specified pattern occurs one time and doesn't
store any samples until then.
• Run until user stop
Sets up to never trigger. You must select the stop button to view the
captured data.
• Find pattern2 occurring immediately after pattern1
Becomes true when the second specified pattern occurs in the sample
immediately after a sample in which the first specified pattern occurs.
• Find pattern1 eventually followed by pattern2
Becomes true when the second specified pattern occurs in a sample
(eventually) after a sample in which the first specified pattern occurs.
• Find pattern2 occurring too soon after pattern1
Becomes true when the second specified pattern occurs within a specified
time after the first specified pattern.
• Find pattern2 occurring too late after pattern1
Becomes true when the second specified pattern does not occur within a
specified time after the first specified pattern.
• Find too few states between pattern1 and pattern2
Becomes true when the second specified pattern occurs within a specified
number of samples (states) after the first specified pattern.
• Find too many states between pattern1 and pattern2
Becomes true when the second specified pattern does not occur within a
specified number of samples (states) after the first specified pattern.
• Find n-bit serial pattern
Becomes true when a specified serial pattern of N bits is found on the
analyzed line.
• Find pattern n consecutive times
