:TRIGger:PATTern:QUALifier
(see page 1088 )
Command Syntax
:TRIGger:PATTern:QUALifier <qualifier>
<qualifier> ::= {ENTered | GREaterthan | LESSthan | INRange | OUTRange
| TIMeout}
The :TRIGger:PATTern:QUALifier command qualifies when the trigger
occurs:
• ENTered — when the pattern is entered.
• LESSthan — when the pattern is present for less than a time value.
• GREaterthan — when the pattern is present for greater than a time
value. The trigger occurs when the pattern exits (not when the
GREaterthan time value is exceeded).
• TIMeout — when the pattern is present for greater than a time value. In
this case, the trigger occurs when the GREaterthan time value is
exceeded (not when the pattern exits).
• INRange — when the pattern is present for a time within a range of
values.
• OUTRange — when the pattern is present for a time outside of range of
values.
Pattern durations are evaluated using a timer. The timer starts on the last
edge that makes the pattern (logical AND) true. Except when the TIMeout
qualifier is selected, the trigger occurs on the first edge that makes the
pattern false, provided the time qualifier criteria has been met.
Set the GREaterthan qualifier value with the
:TRIGger:PATTern:GREaterthan command.
Set the LESSthan qualifier value with the :TRIGger:PATTern:LESSthan
command.
Set the INRange and OUTRange qualifier values with the
:TRIGger:PATTern:RANGe command.
Set the TIMeout qualifier value with the :TRIGger:PATTern:GREaterthan
command.
Query Syntax

qualifier.
Return Format
