pattern. When all the channels are set to X, the oscilloscope will not trigger.)
Return
Format
The query returns the currently set pattern of all the channels. The channels are
separated by commas.
Example :TRIGger:DURATion:TYPE L,X /*Sets the patterns of "CH1 to CH2" to L,X. Other
channel pattern remains unchanged.*/
:TRIGger:DURATion:TYPE? /*The query returns
L,X, X,X,X,X,X,X,X,X,X,X,X,X,X,X,X,X.*/

GREater
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.

800 ps to 10 s
2 μs
Remarks

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