:TRIGger:RUNT:WHEN 
:TRIGger:RUNT:WHEN <when> 
:TRIGger:RUNT:WHEN? 
Set or query the qualifier in runt trigger.   
{NONE|GREater|LESS|GLESs} 
  NONE: do not set the trigger condition in runt trigger.   
  GREater: trigger when the runt pulse width is greater than the lower limit of the pulse 
width (refer to :TRIGger:RUNT:WLOWer).   
  LESS: trigger when the runt pulse width is lower than the upper limit of the pulse 
width (refer to :TRIGger:RUNT:WUPPer).   
  GLESs: trigger when the runt pulse width is greater than the lower limit (refer 
to :TRIGger:RUNT:WLOWer) and lower than the upper limit of the pulse width (refer 
to :TRIGger:RUNT:WUPPer). Note: the lower limit of the pulse width must be lower 
than the upper limit. 
The query returns NONE, GRE, LESS, or GLES.   
:TRIGger:RUNT:WHEN LESS /*Set the qualifier to <*/ 
:TRIGger:RUNT:WHEN?                /*The query returns LESS*/ 
 
 
:TRIGger:RUNT:WUPPer 
:TRIGger:RUNT:WUPPer <NR3> 
:TRIGger:RUNT:WUPPer? 
Set or query the pulse width upper limit in runt trigger. The default unit is s.   
When the qualifier is LESS, the range is from 8ns to 
10s; when the qualifier is GLESs, the range is from 
16ns to 10s. 
  This command is only available when the qualifier (refer to :TRIGger:RUNT:WHEN) is 
LESS or GLESs.   
  When the qualifier is GLESs, the upper limit of the pulse width must be greater than 
the lower limit of the pulse width (:TRIGger:RUNT:WLOWer). 
The query returns the pulse width upper limit in scientific notation.   
:TRIGger:RUNT:WUPPer 0.02 /*Set the pulse width upper limit to 20ms*/ 
:TRIGger:RUNT:WUPPer?            /*The query returns 2.000000e-02*/
