State
Activates the list mode and processes the currently selected list.
Note: Active RF frequency, RF level or RF combined sweep modes deactivate the LF
sweep or List mode and vice versa.
Remote command: 
[:SOURce<hw>]:FREQuency:MODE on page 454
Current Index
Sets the list index for list processing in "Step" mode. In the other modes, the index indi-
cates the current step.
Remote command: 
[:SOURce<hw>]:LIST:INDex on page 479
Mode
Selects the mode for list processing.
See Chapter 6.1, "Signal generation and triggering in the sweep and list modes",
on page 114.
"Auto"
Generates the signal by processing the frequency/level value pairs of
the list from the beginning to the end.
The list steps are performed automatically, controlled by the dwell
time. If you switch from any mode to "Auto", signal generation always
starts at the top of the list.
"Single / Extern Single"
Generates the signal by processing the frequency/level value pairs of
the list once from the beginning to the end after a trigger event.
The list steps are performed automatically, controlled by the dwell
time. If one cycle is completed, the instrument waits for the next trig-
ger event.
"Step / Extern Step"
Generates the signal by processing the frequency/level value pairs of
the list step-by-step, manually triggered.
Remote command: 
[:SOURce<hw>]:LIST:TRIGger:SOURce on page 481
[:SOURce<hw>]:LIST:MODE on page 480
Dwell Time Mode
Selects either variable dwell times or a fixed dwell time to perform signal generation in
list mode.
"Global"
Uses the same dwell time for all lists steps, set with Global Dwell
Time.
"From List"
Uses the dwell times from the list.
You can define the dwell time for each frequency/level value pair indi-
vidually, see Chapter 6.7, "List editor", on page 145.
