Set or query the trigger level in edge trigger. The unit is the same as the current 
amplitude unit of the signal source selected.   
(-5 x VerticalScale - OFFSet) to   
(5 x VerticalScale - OFFSet) 
  For VerticalScale, refer to the :CHANnel<n>:SCALe command. For OFFSet, refer to 
the :CHANnel<n>:OFFSet command.

The query returns the trigger level in scientific notation.   
:TRIGger:EDGe:LEVel 0.16 /*Set the trigger level to 160mV*/ 
:TRIGger:EDGe:LEVel?                /*The query returns 1.600000e-01*/
