channels "D0 to D15".
In the parameter range, H indicates high level (higher than the threshold level of

the channel), L indicates low level (lower than the threshold level of the channel),
and X indicates omitting the channel (This channel is not used as a part of the
pattern. When all the channels are set to X, the oscilloscope will not trigger.)
Return The query returns the currently set pattern of all the channels. The channels are

:TRIGger:DURATion:TYPE?
:TRIGger:DURATion:WHEN
Syntax :TRIGger:DURATion:WHEN <when>
:TRIGger:DURATion:WHEN?
Description Sets or queries the trigger condition of Duration trigger.
Parameter Name
<when>
Remarks GREater: triggers when the set duration time of the pattern is greater than the preset

time.
LESS: triggers when the set duration time of the pattern is smaller than the preset

time.
GLESs: triggers when the set duration time of the pattern is smaller than the preset

upper time limit and greater than the preset lower time limit.
UNGLess: triggers when the set duration time of the pattern is greater than the

preset upper time limit and smaller than the preset lower time limit.
Return The query returns GRE, LESS, GLES, or UNGL.

:TRIGger:DURATion:TUPPer
Syntax :TRIGger:DURATion:TUPPer <time>
:TRIGger:DURATion:TUPPer?
Description
Sets or queries the upper limit of the duration time of Duration trigger. The default unit is
s.
Parameter
Name
<time>
Remarks
This command is only available when the trigger conditions are LESS and GLESs.
Return
The query returns the upper limit of the duration time in scientific notation.

Example :TRIGger:DURATion:TUPPer 0.000003 /*Sets the upper limit of the duration time to 3
