Type
Range
Default
<type>
Discrete
{EXIT|ENTer|TIME}
ENTer
Remarks
 EXIT: triggers when the input signal exits the specified trigger level range.
 ENTer: triggers when the input signal enters the specified trigger level range.
 TIME: triggers when the accumulated hold time after the trigger signal enters the
specified trigger level range is equal to the window time.
Return
Format
The query returns EXIT, ENT, or TIME.
Example
:TRIGger:WINDows:POSition ENT /*Sets the trigger position to ENT.*/
:TRIGger:WINDows:POSition? /*The query returns ENT.*/
:TRIGger:WINDows:TIME
Syntax
:TRIGger:WINDows:TIME <time>
:TRIGger:WINDows:TIME?
Description
Sets or queries the window time of Window trigger.
