:TRIGger:EDGe:LEVel
Syntax
:TRIGger:EDGe:LEVel <level>
:TRIGger:EDGe:LEVel?
Description
Sets or queries the trigger level of Edge trigger. The unit is the same as the current amplitude unit of the
source channel.
Parameter
Name Type
<level> Real
Remarks
The range of <level> is related to the type of the source channel of Edge trigger.
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).
Wherein, VerticalScale is the vertical scale of the source channel, refer to the :CHANnel<n>:SCALe
command; Offset is the vertical position of the source channel, refer to the :CHANnel<n>:OFFSet
command.
External trigger channel (EXT or EXT/5)

The range of <level> is from -800 mV to +800 mV (EXT) or from -4 V to +4 V (EXT/5). The unit is the
same as the current amplitude unit of CH1.
AC line

You do not need to set the trigger level.
Return Format
The query returns the trigger level in scientific notation.
:TRIGger:EDGe:SLOPe
Syntax
:TRIGger:EDGe:SLOPe <slope>
:TRIGger:EDGe:SLOPe?
Description
Sets or queries the edge type of Edge trigger.
Parameter
Name Type
<slope> Discrete
Remarks
POSitive: indicates that the oscilloscope triggers at the crossing point where the rising edge of the

input signal meets the preset trigger level.
