Command
:TRIGger:LEVel[:CHANnel] CHANnel<N>, <level>
Description The command specifies the trigger level when an analog input channel is
used as trigger source.
<N> An integer, 1-4.
<level> The trigger level in volts as a floating point number.

Command
:TRIGger:LEVel:IFMagnitude CHANnel<N>, <level>
Description The command specifies the Intermediate Frequency Magnitude trigger
level when an analog input channel is used as trigger source and the data
processing mode is DDC.
A trigger event is generated, when the power P
pair after DDC processing and decimation is above the specified trigger
level in dBm according to the following formula:
