:TRIGger:DURATion:WHEN 
Syntax  :TRIGger:DURATion:WHEN <when> 
Set or query the trigger condition in duration trigger.  
Parameter 
Explanation    GREater: you need to specify a time (refer to :TRIGger:DURATion:TLOWer). The 
oscilloscope triggers when the duration of the pattern is greater than the preset time. 
  LESS: you need to specify a time (refer to 
:TRIGger:DURATion:TUPPer). The 
oscilloscope triggers when the duration of the pattern is lower than the preset time. 
  GLESs: you need to specify an upper limit of the time (refer 
to 
:TRIGger:DURATion:TUPPer) and lower limit of the time (refer 
to 
:TRIGger:DURATion:TLOWer). The oscilloscope triggers when the duration of the 
pattern is lower than the preset upper limit of the time and greater than the preset 
Return
