Command List:
 :TRIGger:PATTern:LEVel
 :TRIGger:PATTern:PATTern
 :TRIGger:PATTern:SOURce
:TRIGger:PATTern:LEVel
Syntax
:TRIGger:PATTern:LEVel [<chan>,]<level>
:TRIGger:PATTern:LEVel? [<chan>]
Description
Sets or queries the trigger level of the specified channel of Pattern trigger. If <chan> is omitted, the
command sets or queries the trigger level of the current channel (refer to the :TRIGger:PATTern:SOURce
command). The unit is related to the type of the channel.
Parameter
Name Type Range Default
<chan> Discrete {CHANnel1|CHANnel2|CHANnel3|CHANnel4|EXT} CHANnel1
<level> Real Refer to Remarks 0
Remarks
The range of <level> is related to the type of the source channel.
 Analog channel (CH1-CH4
)
The range of <level> is from (-6 x VerticalScale - Offset) to (6 x VerticalScale - Offset) (relative to the
vertical center of the screen). The unit is the same as the amplitude unit of the specified channel.
Wherein, VerticalScale is the vertical scale of the specified channel, refer to the :CHANnel<n>:SCALe
command; Offset is the vertical position of the specified channel, refer to the :CHANnel<n>:OFFSet
command.
 External trigger channel (EXT)
The range of <level> is from -800 mV to +800 mV. The unit is the same as the current amplitude unit
of CH1.
Return Format
The query returns the trigger level in scientific notation.
