:TRIGger:PATTern:QUALifier
(see page 1428)
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.
