Mode
Selects the mode for list processing.
For detailed information on the sweep modes and the triggering, see Chapter 6.1, "Sig-
nal Generation and Triggering in the Sweep and List Modes", on page 156.
"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 619
[:SOURce<hw>]:LIST:MODE on page 618
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 188.
Remote command:
[:SOURce<hw>]:LIST:DWELl:MODE on page 615
Global Dwell Time
Sets the dwell time for Dwell Time Mode > "Global".
Note: In case of considerable overrun conditions, the R&S SMA100B turns off the list
mode.
See also "Dwell time" on page 168.
Remote command:
[:SOURce<hw>]:LIST:DWELl on page 615
Trigger Slope
For "Mode = Extern Step/Single", selects the polarity of the active slope of an applied
instrument trigger.
Trigger signal is expected at the Inst Trig connector.
"Positive"
The rising edge of the trigger signal triggers the instrument.
