{GREater|LESS|GLESs}
GREater
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
Format
The query returns GRE, LESS, or GLES.
Example
:TRIGger:DURATion:WHEN LESS /*Set the trigger condition to <*/
:TRIGger:DURATion:WHEN? /*The query returns LESS*/
:TRIGger:DURATion:TUPPer
Syntax
:TRIGger:DURATion:TUPPer <NR3>

2μs
Explanation
This command is available when the trigger condition (:TRIGger:DURATion:WHEN) is
LESS or GLESs.
Return
Format
The query returns the duration time upper limit in scientific notation.
Example
:TRIGger:DURATion:TUPPer 0.000003 /*Set the duration time upper limit to 3μs*/
:TRIGger:DURATion:TUPPer? /*The query returns 3.000000e-06*/
