:TRIGger:SPI:CLEVel
Syntax :TRIGger:SPI:CLEVel <level>
:TRIGger:SPI:CLEVel?
Description Set or query the trigger level of the SCL channel in SPI trigger. The unit is the same as the
current amplitude unit.
Parameter
Name
Type
Range
Default
<level> Real
(-5 x VerticalScale - OFFSet) to
(5 x VerticalScale - OFFSet)
0
Explanation  For VerticalScale, refer to :CHANnel<n>:SCALe. For OFFSet, refer
to
:CHANnel<n>:OFFSet.
 This command is only available when the signal source of the clock line is an analog
channel.
Return
Format
The query returns the trigger level of the SCL channel in scientific notation.
Example
:TRIGger:SPI:CLEVel 0.16 /*Set the trigger level of the SCL channel to 160mV*/
:TRIGger:SPI:CLEVel? /*The query returns 1.600000e-01*/
:TRIGger:SPI:DLEVel
Syntax :TRIGger:SPI:DLEVel <level>
:TRIGger:SPI:DLEVel?
Description Set or query the trigger level of the SDA channel in SPI trigger. The unit is the same as the
current amplitude unit.
