Trigger Trouble
 
• Verify the channel connections are secure.
 
• Connect at least one ground channel to the test circuit's ground.
 
• Verify the threshold levels are valid for the input signals.
 
• Use the activity indicators to verify the input signals are changing.
 
• Use the "Immediate" TriggerForm to capture a quick trace and verify the signals behave as expected.
 
• Trigger events cannot occur during the Pre-fill Period.
 
• The Custom TriggerForm must use the "Trigger" action on at least one level.
 
• The Custom TriggerForm must reach the "Trigger" action.
 
• Be careful when using the "!=", "<=", or ">=" Trigger Qualifiers. For example, the anything "x" character matches all input values. However, no data input matches an "x" character which also has a "!=" qualifier. Likewise, no data input matches a zero value which also uses the "<=" qualifier.
