:TRIGger:PULSe:UWIDth
Syntax :TRIGger:PULSe:UWIDth <width>
:TRIGger:PULSe:UWIDth?
Description
Sets or queries the pulse upper limit of the Pulse trigger. The default unit is s.
Parameter
Name
Type
Range
Default
<width>
Real
Pulse lower limit to 10 s
2 μs
Remarks The set upper limit cannot be smaller than the lower limit, otherwise, the lower limit
will be automatically changed.
Return
Format
The query returns the upper limit of the pulse width in scientific notation.
Example
:TRIGger:PULSe:UWIDth 0.000003 /*Sets the upper limit of the pulse width to 3 μs.*/
:TRIGger:PULSe:UWIDth? /*The query returns 3.000000E-6.*/
:TRIGger:PULSe:LWIDth
Syntax :TRIGger:PULSe:LWIDth <width>
:TRIGger:PULSe:LWIDth?
Description
Sets or queries the pulse lower limit of the Pulse trigger. The default unit is s.
Parameter
Name
Type
Range
Default
<width>
Real
800 ps to pulse upper limit
1 μs
Remarks The set lower limit must be smaller than the upper limit, otherwise, the upper limit
will be automatically changed.
Return
Format
The query returns the lower limit of the pulse width in scientific notation.
Example
:TRIGger:PULSe:LWIDth 0.000003 /*Sets the lower limit of the pulse width to 3 μs.*/
:TRIGger:PULSe:LWIDth? /*The query returns 3.000000E-6.*/
:TRIGger:PULSe:LEVel
Syntax :TRIGger:PULSe:LEVel <level>
:TRIGger:PULSe:LEVel?
Description Sets or queries the trigger level of Pulse trigger. The unit is the same as that of the
current amplitude.
Parameter
Name
Type
Range
Default
<level> Real
(-5 × VerticalScale - OFFSet) to
(5 × VerticalScale - OFFSet)
0
Remarks  For VerticalScale, refer to the :CHANnel<n>:SCALe command; for OFFSet,
refer to the
:CHANnel<n>:OFFSet command.
 Only when the selected source is an analog channel or an external trigger,
can this setting command is valid.
Return Format
The query returns the trigger level in scientific notation.
Example :TRIGger:PULSe:LEVel 0.16 /*Sets the trigger level to 160 mV.*/
:TRIGger:PULSe:LEVel? /*The query returns 1.600000E-1.*/
