Both commands set the trigger source for the LF sweep (alias commands). The trigger is triggered
by the command :SOURce:LFOutput:SWEep[:FREQuency]EXECute.
The names of the parameters correspond directly to the various settings under manual control. SCPI
uses other names for the parameters; these names are also accepted by the instrument. The SCPI
names should be used if compatibility is an important consideration. An overview of the various
names is given in the following table:
R&S name SCPI name Command under manual control
AUTO IMMediate
Auto mode
SINGle BUS
Single mode.
EXTernal EXTernal
Ext Single and Ext Step mode. The command LFO:SWEep:MODE
is used to select between the two sweep modes.
Parameters: AUTO | IMMediate
The trigger is free-running, i.e. the trigger condition is fulfilled continuously. As
soon as one sweep is finished, the next sweep is started.
SINGle
One complete sweep cycle is triggered by the IEC/IEEE-bus commands
.:LFOutput:SWEep:EXEC or *TRG. The mode has to be set to AUTO
(:SOURce:LFOutput:SWEep:MODE AUTO).
EXTernal
The sweep is triggered externally via the INST TRIG connector.
EAUTo
The sweep is triggered externally via the INST TRIG connector. As soon as
one sweep is finished, the next sweep is started. A second trigger event stops
the sweep at the current frequency, a third trigger event starts the trigger at
the start frequency, and so on.
Example:
TRIG:LSW:SOUR EXT
'selects triggering with an external trigger. The trigger is input via the INST
TRIG connector.
