[:SOURce]:LIST:POWer <Val>{,{Val}}
Function: This command sets the amplitude of each sweep point in current list. If users need to set
different offset for each list point, it is necessary to enter the corresponding offset
value for each point in list, i.e. the amplitude offset of list sweep points in turn,
separated by commas. If the number of points input by users is less than that of the
current list points, the number of points where the list power offset is not entered uses
the current default.
Setting format: [:SOURce]:LIST:POWer <val>{,{val}}
Query format: [:SOURce]:LIST:POWer?
Parameter:
<Val> Ampl Offset of List Sweep Points.
Range: 0dBm [-100dB
，
+100dB].
Example: :LIST:POWer 1dB
，
0.2dB
，
1.3dB
，

[:SOURce]:LIST:RETRace <State>
Function: This command is used for setting RTC switch. After accomplishing the single list sweep,
the output frequency of the signal generator stays on the first or the last point of the list.
This command is only available in the single sweep mode.
Setting format: [:SOURce]:LIST:RETRace ON|OFF|1|0
Query format: [:SOURce]:LIST:RETRace?
Parameter:
<State> Boolean data is as follows:
ON | 1: RTC Switch ON; after accomplishing sweep, the output frequency stays on the
first frequency point of the list.
OFF | 0: RTC Switch OFF; after accomplishing sweep, the output frequency stays on
the last frequency point of the list.
Example: :LIST:RETRace 0 RTC Switch OFF; after accomplishing the single list sweep, the output
CW frequency of the signal generator will stay on the last frequency point of the list.
Reset status: 0

[:SOURce]:LIST:TRIGger:SOURce <Source>
Function: This command is used for setting the trigger source for initiating list sweep. The trigger
sources are available in four modes, namely, Auto, Bus, Ext and Key. For related
command, see the command ―
TRIGger[:SEQuence]:SOURce
‖.
Setting format: [:SOURce]:LIST:TRIGger:SOURce IMMediate|BUS|EXTernal|KEY
Query format: [:SOURce]:LIST:TRIGger:SOURce?
Parameter:
<Source> Discrete data. List Trig is as follows:
IMMediate, the trigger signal is always true, when a sweep is completed, the system
