:TRIGger:DURATion:WHEN
Syntax :TRIGger:DURATion:WHEN <when>
:TRIGger:DURATion:WHEN?
Description Set or query the trigger condition in duration trigger.
Parameter
Name
<when>
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
lower limit of the time.
Return The query returns GRE, LESS, or GLES.

:TRIGger:DURATion:TUPPer
Syntax :TRIGger:DURATion:TUPPer <NR3>
:TRIGger:DURATion:TUPPer?
Description Set or query the duration time upper limit in duration trigger. The default unit is s.
Parameter
Name
<NR3>
Explanation This command is available when the trigger condition (:TRIGger:DURATion:WHEN) is
LESS or GLESs.
Return The query returns the duration time upper limit in scientific notation.
