:TRIGger:RUNT:WHEN <when>
:TRIGger:RUNT:WHEN?
Description
Set or query the qualifier in runt trigger.
Parameter
Name
Type
Range
Default
<when>
Discrete
{NONE|GREater|LESS|GLESs}
NONE
Explanation
 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.
Return
Format
The query returns NONE, GRE, LESS, or GLES.
Example
:TRIGger:RUNT:WHEN LESS /*Set the qualifier to <*/
:TRIGger:RUNT:WHEN? /*The query returns LESS*/
:TRIGger:RUNT:WUPPer
Syntax
:TRIGger:RUNT:WUPPer <NR3>
:TRIGger:RUNT:WUPPer?
Description
Set or query the pulse width upper limit in runt trigger. The default unit is s.
Parameter
Name
Type
Range
Default
<NR3>
Real
When the qualifier is LESS, the range is from 8ns to
10s; when the qualifier is GLESs, the range is from
16ns to 10s.
2μs
Explanation
 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).
Return
Format
The query returns the pulse width upper limit in scientific notation.
Example
:TRIGger:RUNT:WUPPer 0.02 /*Set the pulse width upper limit to 20ms*/
:TRIGger:RUNT:WUPPer? /*The query returns 2.000000e-02*/
