Edge Trigger
:TRIGger:EDGE:SLOPe
 Command format：
:TRIGger:EDGE:SLOPe {POSitive|NEGative|ALTernation}
:TRIGger:EDGE:SLOPe?
 Functional description：
Set edge trigger mode，POSitive, NEGative and ALTernation.
 Return format：
Query return edge trigger mode { POSitive | NEGative | ALTernation }.
 For example：
:TRIGger:EDGE:SLOP POS set edge trigger mode as POSitive
:TRIGger:EDGE:SLOP? query return POSitive
Pulse Width Trigger
:TRIGger:PULSe:QUALifier
 Command format：
:TRIGger:PULSe:QUALifier {GREaterthan | LESSthan | EQUal}
:TRIGger:PULSe:QUALifier?
 Functional description：
Set the term of pulse time, GREaterthan, LESSthan and EQUal.
 Return format：
Query return { GREaterthan | LESSthan | EQUal }.
 For example：
:TRIGger:PULSe:QUALifier GRE set the pulse term as GREaterthan
:TRIGger:PULSe:QUALifier? query return GREaterthan
