For example：

:TRIG:LEV 2
:TRIG:LEV?
:TRIGger:LEVel:LOW
Command format：

:TRIGger:LEVel:LOW <level>
:TRIGger:LEVel:LOW?
Functional description：

This command is used to set low level value of slop trigger. Nuerical value of <level> must be set after the
conversion according to the amplitude volts/div scale and screen information.
Return format：

Query returns the <level> setting value, unit is V.
For example：

:TRIG:LEV:LOW 2
:TRIG:LEV:LOW?
:TRIGger:LEVel:HIGH
Command format：

:TRIGger:LEVel:HIGH <level>
:TRIGger:LEVel:HIGH?
Functional description：

This command is used to set high level value of slop trigger. Nuerical value of <level> must be set after the
conversion according to the amplitude volts/div scale and screen information.
Return format：

Query returns the <level> setting value, unit is V.
For example：

:TRIG:LEV:HIGH 2
:TRIG:LEV:HIGH?
:TRIGger:SOURce
Command format：

:TRIGger:SOURce <source>
:TRIGger:SOURce?
Functional description：

This command is used to set signle trigger source, input channel (CHANnel1, CHANnel 2, CHANnel 3,
CHANnel 4), external trigger (EXT), AC Line (main electricity). EDGE/ PULSe only support AC Line, EXT and
EXT5 source. VIDeo only support EXT and EXT5 source.
<source> represents trigger source, take value from as follows,
CHANnel<n>|EXT|EXT5|ACLINE, <n> take value from 1, 2, 3, 4.
