Command Description R&S SMB
1407.0806.32 6.100 E-2
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:
TRIG0:SOUR EXT
'selects triggering with an external trigger. The trigger is input via the INST
TRIG connector.
*RST value Resolution Options SCPI
SINGle - - Device-specific
TRIGger:FSWeep[:IMMediate]
The command immediately starts an RF frequency sweep cycle. The command is only effective for
sweep mode Single (SOURce:SWEep:FREQuency:MODE AUTO in combination with
TRIG:FSW:SOUR SING). The command corresponds to the manual-control command Execute
Trigger.
This command triggers an event and therefore has no *RST value.
Example:
SWE:FREQ:MODE AUTO
'sets the triggered sweep mode, i.e. a trigger is required to start the sweep.
TRIG:FSW:SOUR SING
'sets the Single trigger mode, i.e. a trigger starts a single sweep.
TRIG:FSW
'starts a single RF frequency sweep.

TRIGger:FSWeep:SOURce AUTO|IMMediate | SINGle | EXTernal|BUS | EAUTo
The command sets the trigger source for the RF frequency sweep.
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 :SWEep:FREQ: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.
